Intergenerational mobility and long-term socio-economic change in Pakistan.

INTRODUCTION
Development process may entail changes in the socio-economic positions of people from one generation to the other. In Pakistan, no
attempt has so far been made to study the lines on which people gain
upward mobility or the factors which are involved in this process. This
paper is an attempt in this direction. By using data from primary
sources, we aim at explaining the income and wealth positions of
Pakistanis from different generations in terms of their endowments of
social, human and physical capital and other socio-economic
characteristics. The assessment of incidence and nature of such mobility
would enable us to identify the processes through which different
socio-economic groups attempt to improve their positions in a changing
society.
To open up this new area of research in Pakistan, a nation-wide
survey was conducted, covering 1200 respondents in the major
industrialized cities of the country. This paper presents some of the
important findings of that survey. An exhaustive analysis of mobility in
Pakistan will be presented in a report which is to follow this paper
[4].
The paper is organized as follows. Section I outlines the
methodological framework of the paper. This is followed by a description
of the sample survey in Section II. Section III contains empirical
findings and their analysis. Section IV presents some tentative conclusions of the study.
I. METHODOLOGICAL FRAMEWORK
Theoretical Framework
A methodology suitable for analysing mobility needs a theoretical
framework which must take into account the two forms which mobility can
take: (a) intergenerational mobility and (b) intragenerational mobility.
In the case of intergenerational mobility, the focus of analysis is on
mobility between the past and the present generations, but in the case
of intragenerational mobility it is the mobility within one and the same
generation that constitutes the object of study.
For obvious reasons, the focus of the analysis should be on
mobility within families. There the mobility is determined by two types
of mechanisms: (a) the transmission of tastes, preferences and
socioeconomic positions within the family and (b) the influence of the
socio-economic development of the 'outside' environment.
Admittedly, these two mechanisms are, to a large extent, interconnected
and can hardly be disentangled. However, on theoretical grounds this
distinction needs to be made.
In principle, a comprehensive study of major socioeconomic mobility
trends in a society like Pakistan can be operationalized by including
the socio-economic profile of: (a) the father and the father-in-law of
the past generations, (b) the respondent and his wife and brothers, and
(c) the sons and daughters of the respondent. These 'actors'
in the mobility analysis are shown in Figure 1.
In this figure, the upper three boxes illustrate the interaction of
the socioeconomic positions among three generations of one family
resulting from their endowments of social, human and physical capital.
The lower box shows the influence of overall development, such as
political events, government policies, and technological, economic and
social trends on the positions of different generations.
[FIGURE 1 OMITTED]
Analytical Framework
In accordance with the theoretical framework, the pilot survey
gathered a wealth of information on socio-economic characteristics of
the 6 actors shown in Figure 1.
Within this framework, the paper would first try to describe the
profiles of father and sons in terms of their geographical, educational,
demographic, occupational and financial characteristics, and then point
out the changes in these profiles that have occurred from one generation
to the other. Elements of a profile may tend to be associated with one
another; for example, income level of a person may be associated with
his educational achievements. Such associations could provide a
stylization of the kind of environment in which an actor operates. The
analytical framework developed here will attempt to describe such
environment by using intercorrelations for two actors: (a) sons and (b)
fathers. By comparing the two types of intercorrelations, one could
monitor changes taking place over time in the socio-economic
environments faced by different generations.
Any study of long-term socio-economic changes in population groups
needs to define measures of mobility. In this respect, the unit of
analysis for defining mobility can be the family or the individual
within the family. In the first case, one can see how mobile the family
is as a whole in terms of its performance regarding wealth,
income', working status, occupation and place of residence. In the
second case, the focus is on the individual. It is also possible to
distinguish between intergenerational and intragenerational
performances. In the former case, we look into differences between the
past and the present generations, whereas in the latter case, mobility
is defined within one and the same generation.
These four levels of mobility analysis are presented in Figure 2.
The mathematical formulations of the four mobility indicators can
be expressed as follows:
[RI.sub.i] = [C.sub.ij]/[C.sub.kj] i = 1, 2 .... n; j = 1, ...., m
... (1)
[RF.sub.j] = [[bar.C].sub.ij]/[C.sub.kj]. i = 1, 2 .... n; j = 1,
...., m ... (2)
of which [[bar.C].sub.j] = [n.summation over (i=1) [C.sub.ij]/n
[AI.sub.i] = [C.sub.ij]/[C.sub.j] ... ... ... ... ... (3)
[AF.sub.j] = [[[([n.summation over (i=1)] [C.sub.ij] -
[[bar.C].sub.j]).sup.2] / n].sup.1/2] ... ... ... ... (4)
where C stands for a characteristics of mobility; i for the ith
individual (son) from the present generation; j for family; and k for
individual (father) from the past generation.
The relations (1) to (3)are ratios, whereas the fourth one is
standard deviation. The ratio (RI) measures the mobility of an
individual (son) of the present generation compared with that of his
father, whereas the second ratio (RF) expresses this relation between
the average performance of all individuals (sons) of the present
generation and that of their fathers. The third ratio (AI), however,
compares within one generation the average performance of all
individuals (sons) in a family against the performance of each
individual in the same family. Finally, the fourth relation (AF) is the
standard deviation of a characteristic within the same family.
With regard to the interpretation of the values of the four
mobility indicators, it is noted that in the cases of ratios (1) to (3),
upward (positive) mobility is observed when the values of the indicators
are above 1 and downward (negative) mobility is indicated when the
values of the indicators are below 1. In the case of the fourth
indicator (AF), which is in principle an inequality measurement, high
values signify high mobility and vice versa.
To estimate these indicators, one could, in principle, use a number
of characteristics of an individual, important among which could be
income, wealth, occupation, working status and place of residence of a
person. But not all of these characteristics can be easily expressed in
standardized units and made comparable with some degree of accuracy.
Income and wealth are perhaps the only two characteristics which can
easily be made comparable across individuals over time and space.
Therefore, this paper limits the analysis only to these two
characteristics. In the forthcoming report [4], an attempt will be made
to utilize the other characteristics.
To estimate the wealth of an individual, however, is not an easy
task. Not all forms of wealth can be accounted for, particularly when an
individual is asked to disclose his wealth. Experience has shown that
the individual is less reluctant to provide information on the
accumulated wealth in terms of land, houses and plots (residential and
commercial). Therefore the total wealth of the individual is estimated
from these three types of wealth. Moreover, the income of the individual
was estimated by totalling the incomes from his main job as well as from
other jobs and investment, to calculate total factor income.
Although this analytical framework has comprehensively discussed
the applicable mobility indicators by four levels of analysis, the focus
of this paper will be only on the intergenerational aspect of mobility.
Our mobility analysis will, therefore, focus on RI and RF.
II. DATA COLLECTION
Since ours is a pilot study, we are not interested here in
analysing the magnitude of mobility as such. Instead, our interest is in
studying the nature and shape of the transition process. In view of
this, we did not try to select an essentially random sample. Especially
in a country like Pakistan, which has experienced a gradual transition
from a traditional agrarian society to a modern industrialized and
service-oriented society in the last three decades, it is appropriate to
select those pockets of the labour market where mobility and social
changes are expected to have gained momentum. Therefore, the study makes
use of a selective sample and not a random sample: while selecting the
sample of respondents, we focused on male individuals engaged in the
modern, non-agricultural sector of the economy, and residing in the
major industrialized cities of Pakistan.
In all, 1200 respondents from 10 major city districts (1) were
selected to provide information about their own personal characteristics
as well as about the personal characteristics of other
'actors' of the family. The distribution of the urban and
rural non-agricultural male working force in the 10 city districts was
generated as a proxy for distributing the 1200 respondents. The focus on
the modern segment of the labour market was incorporated by selecting 70
percent wage-earners and 30 percent non-wage-earners within each
district, which is a reversion of the actual distribution of the overall
pattern observed in the labour market of Pakistan in 1982 [2;3]. The
distribution of respondents by sectors of production was derived from
the overall sectoral distribution in Pakistan by making the necessary
adjustment for the agricultural sector. This is to say, the agricultural
sector was dropped and the sectoral distribution was recalculated to one
hundred percent.
Finally, the survey was directed at respondents who were older than
40 years of age and they were interviewed at the places of their work.
The reason for going for a particular age group was to make sure that
the respondents had children of a mature age, and also that almost all
males of the second generation were actively engaged in the labour
force.
III. EMPIRICAL RESULTS AND ANALYSIS
Socio-economic Profiles of 'Actors'
The profile descriptions are based on the socio-economic
characteristics presented in Tables 1 and 2. In Table 2, a distinction
has been made between all sons and those whose fathers are alive and
working as well as between all fathers and those alive and working, a
distinction which is needed later in the analysis. In Table 1 this
discrimination is not incorporated because differences in these
characteristics of fathers are minor.
The profile of sons covers all males of the second generation who
are actively engaged in the labour market. This implies that they are
either working or looking for a job. Owing to the fact that only those
respondents were selected who were older than 40 years, most of the
second-generation males are included in this profile analysis of sons.
The sample covered a total of 3722 sons (including 1199 respondents), of
which 175 had died by the time of the survey. Looking at Table 1, one
finds that 38.9 percent of all sons originated from India as compared
with 42.9 percent of the respondents. This percentage is compensated for
by a higher percentage of sons originating from the four provinces of
Pakistan, particularly Punjab and Sind. By place of residence, the
sons' distribution in the four provinces of Pakistan is slightly
lower because 5.5 percent of the sons are working abroad and 1.4 percent
are still residing in India. Admittedly, the percentage of sons working
abroad differs from the generally observed level of sons working abroad
by 10 percent [3]. Moreover, it is observed that 19.8 percent of sons
(the same as for respondents) were born in rural areas.
Regarding the working status, the profile of 'all sons'
differs considerably from that of the respondent. Only 9-3 percent of
them had the status of an employer as compared with 16.3 percent of the
respondents. For the group of employees in the government sector, about
the same percentage (27.1 percent) is found for 'all sons'
case, but for the status group of employees in the private sector a
slightly higher percentage is observed (19.0 percent versus 17.2 percent
for all sons). From the above comparison it follows that the percentage
of the self-employed is higher (42.0 percent versus 38.8 percent) for
all sons. Moreover, 1.2 percent of 'all sons' are unpaid
family workers and 1.4 percent are unemployed. These results indicate
that the pattern of working status becomes more representative of the
actual pattern in the labour force. Moreover, the inference drawn
earlier still holds that in comparison with the pattern of fathers,
there is a transition from non-wage to wage employment.
As regards the descriptive statistics of 16 characteristics, the
focus will be on 'all sons' with a brief comparison with those
sons whose fathers are alive and working.
As expected from the selection of respondents 40 years or older at
the time of the survey, the average age of 'all sons' is
somewhat lower (46 years). The average education is slightly lower than
that of the respondents (12.5 years which is 4 percent lower). The
income from main job is Rs 5815, which is 7 percent lower than the
income of the respondent. To determine this income so that it could
correspond to that of fathers, we isolated the effect of the deceased sons. Also, the income from other jobs and investment (Rs 375) is lower
by 52 percent. The income from family
transfer (Rs 216) is lower by 56 percent. Looking at wealth
characteristics one finds that on average the value of the house owned
by sons was Rs 293, 558, which is 11 percent lower than that of the
respondents. The value of agricultural land (Rs 119,196) and residential
urban plot (Rs 16,135) are respectively 2 percent and 80 percent lower
than the values for respondents only. The number of children (3.9) is 18
percent lower and the percentage of those sons who performed Umra/Haj is
11 percentage points lower than that of the respondents. The average
number of years worked abroad is 0.8 years and the average number of
relatives in high positions is 0.7. Only 13.6 percent of the sons have
worked abroad with an average of 5.9 years. Although the percentage of
respondents who have worked abroad is the same as of the 'all
sons' subgroup, the average number of years for those who have
worked abroad is 3.5 years. The percentage of 'all sons' who
have relatives in high positions is 36.8 percent. This percentage was
43.6 in the case of respondents. However, the average number of
relatives of 'all sons' and respondents is the same (1.8).
Consequently, it would appear from the above that respondents are ahead
of their brothers in education, income from main job, property owned,
status and occupational indicators, by 4 percent to 13 percent.
When restricting the sample of all sons (3722 cases) to those sons
whose fathers are alive and working (1016 cases), one observes a general
decline in the performances of most characteristics. Only years of
education increase by one year to 13 years. This decline is primarily
caused by the younger age distribution of 'all sons', which in
turn causes wealth and income components to go down.
It is striking to observe that in comparing the fathers with
responding sons, it appears that in several respects there is an
improvement for the responding son by about 40 percent. A generational
progress of 40 percent can be noted for the number of educational years
(9 for fathers, 13 for sons), monthly income (Rs 4401 vs Rs 6199), value
of house owned (Rs 247,242 vs Rs 326,553), share of self-employment (38
percent vs 43.2 percent), and share of agricultural and production
workers (59 percent vs 39 percent).
Profile Associations and their Changing Patterns over Time
The interrelationships between the socio-economic characteristics
of fathers and sons and their changing patterns over time will be
analysed with Pearson correlation coefficient (r) matrices. Correlation
matrices of fathers and 'all sons' are presented in the upper
and lower blocks of Table 3, respectively. Before explaining these
results, let it be noted that the first 6 characteristics, namely value
of wealth and total factor income, age, years of education, years worked
abroad, and 'number of relatives in high positions are continuous
variables, whereas the last four variables relating to working status,
occupations, place of birth and place of residence are ordinal variables. Different ranks have been used to define these variables.
The occupational categories, for instance, have been ranked from 1
to 8 according to the first digit 'Standard Classification of
Occupations' of which the categories of production, agricultural,
service, sales, clerical, managerial, non-technical, and technical
workers have been set from 1 to 8, respectively. Here, it is noted that
the army personnel have not been included in the ranking, because of
their heterogeneity in military ranks and, hence, in socio-economic
positions.
The working status categories have been ranked from 1 to 6 for
unemployed, unpaid family worker, self-employed, employee in the private
sector, employee in the government sector, and employer, respectively.
The places of birth and residence have been ranked according to the
level of development of the province/country. That is, Baluchistan and
NWFP have been ranked 1, Punjab and Sind 2, and others which include
India, Middle East, Europe, USA/Canada, Bangladesh and Asia ranked 3.
1. After comparing the number of significant correlations [with
explaining variance above 1 percent (r [greater than or equal to] 0.10)]
between the characteristics of fathers and sons, the general impression
that emerges is that the socio-economic environment of the present
generation shows more coherent (i.e. stable and significant) patterns
for improvement of economic position in terms of income and wealth. (See
also points 3 and 4 below).
2. In the cases of both fathers and sons, one can observe the
labour market interrelationships between education, working status,
occupation and network. In addition, it is interesting to note that the
increased availability of educational institutions in Pakistan over time
has led to the absence of correlation between age and education in the
case of sons, while it is still negatively associated in the case of
fathers.
3. It is observed that all the labour market characteristics
mentioned under point 2 correlate significantly at an acceptable level
of correlation (i.e. r [greater than or equal to] 0.1) with the level of
income in the case of sons. However, in the case of fathers, these
correlations are absent. One might suggest that up to now the
improvement of the income positions of sons, as compared with those of
fathers, shows more coherent and stable patterns. Admittedly, only
through partial-correlation analyses can the direct correlation of each
labour characteristic with the level of income be ascertained. However,
on theoretical grounds, the correlations are justified.
4. Also, regarding the level of wealth, the labour market
characteristics (except education) show correlation only in the case of
sons. Again, the distinction in patterns of wealth accumulation between
fathers and sons shows that over time the improvement in economic
position (i.e. in terms of wealth) follows more coherent patterns.
5. As regards the correlations of the geographical characteristics
with places of birth and residence, the following can be observed. In
the cases of both fathers and sons, the correlation is observed between
places of birth and residence. This could be the result of the possible
facts that (a) fathers and sons originating from a place also reside in
the same place; and (b) those sons and fathers who migrated from India
moved mainly to Punjab and Sind. Moreover, the migration patterns
stemming from the employment of Pakistanis abroad (i.e. Middle East,
Europe and USA/ Canada) explains the correlation between the years
worked abroad and the places of residence of sons. Here also, the
positive correlation between sons' age and places of origin should
be mentioned because it could later emerge as an explaining factor in
the incidence of mobility, in our analysis. This last correlation
indicates that the ages of sons originating from India are, on average,
higher than the ages of those sons who originated from the four
provinces of Pakistan, the outcome of the migration of fathers to
Pakistan.
Intergenerational Mobility
The analysis of intergenerational mobility is done in three steps.
Firstly, the results are presented relating to the magnitude and
incidence of such mobility for both individual and family cases. This is
done by using wealth and income criteria separately. In the second step,
we study the relationship of mobility indicators (ratios) with
socioeconomic characteristics. This exercise, while complementing some
of the earlier analysis, should bring sharply into focus those variables
which have played a key role in intergenerational mobility in Pakistan.
In the final step, the incidence of upward mobility by places of birth
and residence, working status and occupations is considered, of which
the inferences are only summarized in Section IV.
1. Table 4 presents estimates of the occurrence (incidence) of
income and wealth mobility for sons individually and as
'families', compared with their fathers, as well as the
magnitudes of such mobility. As regards the magnitudes, these estimates
show that the individual sons, on average, have 4.15 times as much
income as their fathers but 5.3 times as much income as families. In the
case of wealth, they hold about 84 times and 88 times as much wealth as
their fathers, as individuals and as families, respectively. Even
without looking at standard deviations (SD) of these ratios, one can see
that wealth distribution among sons is far more skewed than income
distribution. It appears that in the case of wealth ratios, there were
certain cases of sons having many times as much wealth as their fathers,
which pushed the average of these ratios upward. Estimates of SD of
wealth ratios also convey a high degree of inequality of wealth
distribution among sons in our survey.
When turning to family level, it seems that income is more unevenly
distributed at the family level than at the individual level. This is
signified in particular by the high value of SD of the ratio based on
family income. An increase in the mean and SD of these ratios in the
case of family data indicates that at high levels of family income,
income distribution appears to become relatively more skewed within the
family. But we must remember that the above estimates are based on a
selective sample and their exact magnitudes may, therefore, change when
a pure random sample is used.
For the wealth indicator, the magnitudes at individual and family
levels are about the same. This signifies that the inequality in average
attained wealth of sons between families is still substantially due to a
minority of sons within a family attaining relatively high wealth as
compared with other sons. As regards the incidence of intergenerational
mobility, Table 4 indicates that at the individual level, using wealth
criterion only, 31 percent sons have done better than their fathers.
However, using income criterion, the incidence of upward mobility goes
up to 60 percent. It has also been observed (but not reported here) that
there were 56 percent cases in which wealth ratios were equal to zero.
Therefore, low cases of wealth mobility can be partly explained by the
fact that there was a large percentage of sons who did not have any
wealth at all. This, however, could not have been the case of income
where most of the sons were gainfully employed.
These results could also indicate that in the present generation
not many people accumulate wealth in the same forms in which the past
generation did. Furthermore, since age was observed to be one of the
most important factors associated with wealth, one should, not, in
general, expect the younger generation to accumulate as much wealth as
could be done by the older generation.
At the family level, on both wealth and income grounds, the
incidence of intergenerational mobility has increased. It is 38 percent
in the case of wealth and 65 percent when income criterion is used.
These results imply that, compared with individuals, in more cases
families as a whole performed better than the past generation. A simple
reason for increase in these percentages is that the analysis at the
family level incorporates dispersion of wealth and income within the
families of the present generation.
2. Table 5 presents coefficients of correlation between mobility
indicators (i.e. WR and IR) and different characteristics of
'fathers' and 'sons'. The main features of these
estimates are as follows:
(i) In almost every situation, ages of fathers and sons appear to
be very closely associated with intergenerational mobility. The ages of
these 'actors' were also observed to be closely associated
with their absolute income and wealth (Table 3). In the present context,
these results may imply that if ages in Pakistan go up, the income and
wealth mobility of the present generation may also go up.
(ii) As regards the labour characteristics in terms of occupation,
working status and education, it is the fathers' characteristics
which exert their influence on income and wealth mobility through a
significant and coherent pattern. At the individual level, it is, in
particular, fathers' occupation, working status and education that
influence income mobility and, in particular, fathers' occupations
and education which influence wealth mobility. At the family level, it
is again fathers' occupation and education which influence wealth
mobility and only fathers' working status which influences income
mobility. At the individual level, only two characteristics of sons,
namely "working status' and 'occupation', show
positive relationships with their wealth and income mobility. However,
these relationships do not seem to be very significant and coherent. In
terms of wealth mobility, the positive influence of sons'
occupation, even though positively correlated with WR, also does not
reach an acceptable level of correlation (r [greater than or equal to]
0.1). As regards income mobility, the sons' occupation shows a high
degree of association with it. In addition, it should be mentioned that
sons' network also exerts significantly positive influence on
wealth mobility.
(iii) Turning to the geographical characteristics, the 'places
of birth' of fathers and sons seem to play a significant role in
sons' wealth mobility. At both the individual and the family
levels, 'r' is greater than 0.1. This may indicate that those
sons whose fathers, or who themselves, originated from Punjab, Sind and
India stood greater chances of gaining wealth mobility.
The places of residence correlate with income mobility only in the
cases of sons. Through intercorrelations, brought out in the preceding
analysis, with sons' places of residence, one could also see the
'number of years worked abroad' correlating positively with
their income mobility. As a corollary of this, one might suggest that
sons living at present in the Punjab, Sind and abroad have a relatively
high chance of surpassing their fathers in incomes.
IV. CONCLUSIONS
The pilot survey on intergenerational mobility and long-term
socio-economic change was purposely biased to cover those families which
might have gained socioeconomic mobility. It is essential that we
reiterate this bias to set the background for the following concluding
remarks.
1. The analysis of correlations between the absolute level of
income and wealth vis-a-vis the fathers' and sons'
characteristics has shown that the improvement in the economic position
of sons follows a more stable and coherent pattern than the improvement
in fathers' economic position.
2. The analysis of the magnitudes of mobility indicators shows that
the dispersion of accumulated wealth is considerably higher than that of
income among individual sons. Moreover, when comparing the magnitudes of
mobility at the individual level with those at the family level, it was
observed that the income mobility indicator was higher at family level
than at the individual level. The wealth mobility indicator, on the
other hand, increased only slightly. However, in both cases it indicates
dispersion of income and wealth within the family, which increases with
the increase in the average income and wealth of the family. In
addition, it was observed that inequality in income increased when we
moved from the individual to the family level income.
3. The analysis of correlations between the wealth and the income
indicators vis-a-vis fathers' and sons' characteristics shows
that fathers' labour characteristics, in particular their
occupations, working status and education, provide significant and
coherent patterns for improvement of economic positions of sons. This
pattern could be discerned at both the individual and the family level.
In addition, it may be mentioned that the sons' social network also
exerts an important and positive influence on their mobility.
4. Additional analysis of the incidence of intergenerational
mobility shows that wealth mobility by places of origin and residence is
sensitive to influx of migrants' fathers from India. This is so
because they had less wealth at present than the average held by
'all fathers', probably due to loss of wealth associated with
their dislocation from India after the subcontinent's partition in
1947. It is also observed that the incidence of mobility differed
significantly across the four provinces (of Pakistan) by places of birth
and residence of sons and fathers. However, when performances of sons
are combined in terms of income and wealth mobility, one can not rule
out the tentative conclusion that sons from the NWFP and, to some
extent, Baluchistan did not move upward as much from their parents'
economic positions as was done by their counterparts in Sind and the
Punjab.
5. The analysis of incidences of upward wealth and income mobility
by working status and occupations has shown that the results are
sensitive to the transition process between fathers and sons in the
labour market, from non-wage to wage-employment, and from low-paid and
less skilled jobs to highly paid and more skilled jobs.
Comments on Intergenerational Mobility and Long-term Socio-economic
Change in Pakistan
The study aimed at describing the patterns of intergenerational
mobility with a view to discerning the causative factors and has come up
with some plausible concluding statements. I was unable to fully
appreciate its findings, partly because of the authors'
insufficient explanations, which may be due to the fact that this study
is part of a larger ongoing project. My more substantive objections
relate to poor methodology, data and statistical techniques/inferences.
i. Methodology: The present comparisons are for fathers and sons of
different ages at the same points of time. Logical comparisons can only
be made at .the same age on different points of time. Same reasoning
would apply to both individual and family mobility indices. Needless to
mention, there would be a need for discounting price increases and other
social development.
ii. Data: In Table 2, the average age of respondents is 49 as
compared with 46 of their sons; the too small gap of 3 years between two
generations reflects data problems. Similarly, a decrease in the average
education of sons, compared with the average for the respondents, is not
believable. Income and wealth descriptions in Tables 2 and 4 are
inconsistent. Similarly, other implausible statements point to the need
for checking the data and calculations for their correctness.
iii. Statistical Techniques:
a. The authors have used arbitrary measurements of variables like
social network, occupation, work status, province/region of residence
and birth in defining correlation coefficients, perhaps because without
this trick some of the calculations will not be supportive.
b. In spite of the foregoing trick, the statistical evidence is
very weak and most of the correlation coefficients are very small; e.g.
see Tables 3 & 5.
c. Despite their deliberate choice of a specific restricted
population/ sample, the authors have made liberal inferences about
national/ provincial characteristics of overall population, labour force
and mobility patterns. It is interesting to note the characteristics of
the selected sample which have been selected by the authors: only the
most progressive persons, 40 years or more, in the non-agricultural
modern sectors in major industrialized cities, majority of whom were
born in India, 25 percent of whom had performed Haj/Umra, one-third of
whom have high-position relatives, and who have income 3 to 5 times the
average level, etc., have been included in the sample. Certainly these
characteristics are not representative of the country or of any province
and hence the observed similarities are simple coincidence and not
significant inferentially.
Apart from the foregoing shortcomings,
a. the study has totally ignored females and family composition
(number; sex) which would a priori seem to be logical factors in
individuals' ability to save, for self-development and for
social/economic position.
b. somewhere in the analysis it is maintained that income/wealth
and age are not correlated. The weak correlation is a manifestation of
non-linear relationship between income and age. Given the age structure
of the sample, the relationship may have to be modelled with some
non-linear technique.
c. the analysis did not consider any variable which could be
brought under policy focus.
In view of the weaknesses mentioned above and the fact that the
study is only a pilot sutdy, its contribution is only marginal. The
study thus needs to be thoroughly revised on the lines mentioned above.
