A re-examination of fertility transition in Pakistan.
Soomro, Ghulam Yasin
Pakistan is passing through an early stage of fertility transition.
The slow-paced transition has been analysed in an earlier study done by
Sathar and Casterline (1998), which concludes that the increase in the
levels of prevalence has accelerated the fertility transition in
Pakistan and as a consequence marital fertility has declined. However,
this claim is not supported by the relevant statistics. A re-examination
reveals that the effect of contraception is the lowest in the decline of
fertility. The rise in mamages and breastfeeding has played a
significant inhibiting role in the decline of fertility and marital
fertility has remained constant. The structural adjustment programme
(SAP), initiated in late 1980s, has led to more poverty and the
proportion of never-married has increased in Pakistan as revealed by the
Population Census 1998. Labour force participation by the females
increased in the post-SAP period. The new economic situation appears to
be indirectly responsible for the decline of fertility, and it appears
to be consistent with the Malthusian macro theory of fertility.
INTRODUCTION
Fertility transition is a transformation from a natural fertility regime to a regulated one depending upon the rate of decline in the
total fertility rate (TFR). The pace of this transition in Pakistan has
been very slow despite the fact that a family planning programme was put
in operation about 35 years ago to bring about a rapid decline in
fertility levels. The TFR remained constant through early 1960s to late
1970s [Farouqui and Farooq (1971); Population Planning Council (1976)].
However, a slight decline in TFR was revealed in the Pakistan
Contraceptive Prevalence Survey 1984-85 [Population Welfare Division
(1986)], where it shifted from the level of 6.3 to a new level of 6.0.
The onset of fertility transition has since been observed in the
succeeding surveys, which show very slow progress.
The problem of slow transition mostly relating to supply side, if
viewed at aggregate level, encompassed the entire social sector
including the family planning programme. The presumed latent demand for
fertility regulation was not crystallised through a strategic
implementation of the population policy. The unmet need repeatedly
revealed in the previous population surveys remains an unassailable task
for the management. The sustained level of widespread contraceptive
knowledge, unmet need, and the decline in fertility aspirations have not
capitalised to a level where a rapid pace in fertility transition
towards a regulated reproductive behaviour can be envisioned in the near
future. Many surveys have indicated that the use of contraception has
largely been for the limiting purposes among the high parity women,
indicating that the programme, after many years of operation, remained
at the infancy stage for a longer duration than the other Asian
programmes of similar age. The programme success can be gauged by the
amount to which it increasingly covers women who are at their prime
reproductive age and use methods for parity-specific restraint on
fertility.
The slow-paced fertility transition was analysed by Sathar and
Casterline (1998) arguing that "The decline is gentle but
nevertheless represents a genuine break from the past, most notably
because of the increasing use of modern contraception for the purpose of
limiting family size". The finding of the study that the increase
in contraceptive use led to the decline in marital fertility ("This
rise in [the] proportion of married women using contraception is the
most compelling evidence that marital fertility is declining") was
not supported by the data in that study. This unsubstantiated result
does not hold when analysed using the same data set. In the analysis,
Sathar and Casterline (1998) argued that "All demographic analyses
point to a decline in fertility in the 1990s". However, a plausible
explanation for the significance of the period of 1990s in the decline
of fertility was not offered, one that would be consistent with the
macroeconomic theory of fertility. These three weak areas of the study,
namely, dominant role of contraception in fertility transition, decline
in marital fertility, and the significance of the period of the 1990s,
are being re-examined here partially with the help of the Proximate Determinants of Fertility Model developed by Bongaarts. [Bongaarts
(1978).]
The TFR is a standard measure of fertility and is heavily
influenced by the proximate determinants that keep changing as time
progresses, and produce varied degrees of influence on TFR that remain
concealed if fertility transition is viewed simply by levels of TFR
alone. The TFR is heavily influenced by the changes in the timing of
births in a population even if completed fertility remains the same and,
therefore, is not used as an indicator for completed fertility.
Although one may observe an increase in the prevalence rate, it
cannot be concluded that it will produce a proportional decline in
fertility unless controlled for other proximate determinants, especially
when the prevalence levels remain low with a declining trend in the
breastfeeding levels in Pakistan.
The experience with the World Fertility Survey-75 (WFS) led
Bongaarts to redefine fertility transition in terms of the levels of TFR
ranging downwards from 6.0 and over to 3.0 and less into four phases,
each one delineated by compatible levels of proximate determinants that
would transform the transition from a natural fertility level to a
regulated one distinctly marked by higher prevalence levels [Bongaarts
(1984)].
When viewed within the framework of Bongaarts' transition
model, the slow-paced fertility transition in Pakistan has been passing
through the earlier stage of transition phase one if looks at it by the
prevalence level, and in phase two if evaluated at the level of TFR,
where the registered decline in TFR may not produce a similar proportion
of downwards trend in marital fertility due to the momentum effect of
fertility-enhancing factors flowing in from the natural fertility
regime. This is probably the reason why fertility, when observed through
the TMFR, does not show a concurrent decline apparently witnessed in the
TFR.
The objective of this paper is to analyse the dynamics of the
proximate determinants which were considered mainly responsible for a 15
percent observed decline in the TFR during more than one generation long
period, and to quantify the amount of family planning programme
contribution in this decline. The aggregate measurement of the family
planning programme contribution will include both programme and
non-programme efforts. Moreover, the prevalence rate of 24 percent,
which includes traditional methods, was used in the calculations. The
benefit of the inflated programme effect will not be netted out in this
paper.
The secondary sources of data from various previous surveys
[Population Planning Council (1976); NIPS (1992); NIPS and LSHTM (1998)]
have been utilised in this paper. The data collection methodologies for
the surveys are explained in the first reports of the respective
surveys.
ESTIMATION OF FERTILITY DECLINE
The observed decline in fertility was registered as only 14 to 15
percent from the 1975 to 1996 (Table 1). The age-specific decline
witnessed in the first two age groups of 15-24 appears to be related
more to rising age at marriage than to a deliberate control of fertility
for spacing purposes. There appeared to be a gradual decline in
fertility between the age groups of 25-39 years. There is almost
non-existent decline in fertility for the age group of 40-44, and
interestingly an increase in the last age with a varying degree of
magnitude both in the Pakistan Demographic and Health Survey (PDHS)
1990-91 and the Pakistan Fertility and Family Planning Survey (PFFPS)
1996-97 surveys. Similar findings were also reached when fertility
trends were analysed using parity progression ratios (PRR) in a cohort
analysis which concluded that "there is also a substantial
proportion of women who have not participated in the fertility
transition, so that the higher parities continue to be sustained at a
high level". [Blacker and Hakim (1999).]
The total decline in TFR from the period between PFS-75 and DHS-91
appeared to be 14 and 15 percent when estimated in between PFS-75 and
PFFPS-97. The decline in the TFR is also estimated through the changes
in proximate determinants using the Jain and Adlakha (1982) method to
indirectly judge the consistency level between observed and derived
change in the TFR. The indirect estimates of the change in fertility
appear to be very close to the observed change in fertility (Table 2).
The inhibiting effect of non-marriages increased over time, whereas
the index of breastfeeding shows an opposite effect from the PFS-1975 to
the PFFPS-1997 and lost its inhibiting effect over time. Despite the
declining trend in breastfeeding, it still exerted the same level of
effect as compared to the effect of non-marriages. The inhibiting effect
of contraception increased over time, but not to the level observed for
the other factors (Table 2).
However, there appears to be a slight over-estimation in the
measurement of the magnitude of fertility decline as compared to the
observed decline that ranges in between 14 and 15 percent. The
overestimate of change in fertility in between 15 and 19 percent decline
is indicative that there was more than 10 percent of decline in
breastfeeding levels during the two time-periods. [Appendix Table A1].
[Jain and Adlakha (1982)].
INHIBITING EFFECT OF PROXIMATE DETERMINANTS
The observed fertility levels found in the three previous surveys
are adjusted with the total fecundity which provided the number of
births prevented per woman, and are prorated according to the indices
derived through the Bongaart's method to study the individual
effect of each proximate determinant in the reduction of births. The
total fecundity level used in the paper is 14.5 as established by the
previous research. [Sathar (1984)].
The impact of the rise in age of marriage played an important role
and its effect increased from 29 percent to 38 percent by the year 1996
and decreased by almost 3 births. The effect of contraception in the
decline of natural fertility also increased from a mere 6 percent in
1975 to 24 percent in the year 1996, or it increased from the reduction
of half a birth to two births by the year 1996. (Table 3.) However, the
effect of decline in breastfeeding levels contributed to a decline of
fertility with a declining trend in its inhibiting effect, with a
decrease from 65 percent in 1975 to 38 percent in the year 1996, or from
the reduction of 5 births in 1975 to 3 births in 1996. The continuous
decline in breastfeeding (1) implies the need for higher levels of
prevalence to compensate for the loss in inhibiting effect due to
declining trends in breastfeeding.
However, the effect of contraception appeared to be the lowest in
the decline of fertility when compared to the effect of other proximate
determinants, and this result is opposite to the one given in an earlier
study (Table 3). [Sathar and Casterline (1998).]
FERTILITY TRANSITION AND MARITAL FERTILITY
At the early stage of fertility transition, as is the case in
Pakistan, the decline in TMFR is preceded by the decline in TFR.
However, decline in TFR cannot be equated for a proportional decline in
natural TMFR unless the prevalence levels rise well above the other
lingering natural fertility-related neutralising effects. Bongaarts
observed from the experience of World Fertility Survey (WFS)
participating countries that marital fertility declines very slightly
during the initial phase of fertility transition [Bongaarts (1984)]. On
the other hand, research findings from India suggests that "time
series data also suggest that as use spreads within the population, it
may initially be accompanied by a constant or even increasing natural
marital fertility. Not possibly until 50 percent or more of women aged
35-44 are controlling fertility does observed marital fertility
decline". [Srinivasan, Jejeebhoy, Easterlin and Crimmins (1984)].
Because of this drawback of the stubborn nature of MTFR at the
initial stage of transition, marital fertility is not regarded as a good
indicator of the stage of a phase in fertility transition [Srinivasan,
Jejeebhoy, Easterlin and Crimmins (1984)]. The estimates of MTFR suggest
that marital fertility in Pakistan has remained well above 7.00 and the
observed fluctuations in the estimates across the surveys are probably a
result of the sampling errors.
The estimate of reported MTFR in the first report of the PFFPS-96
was 7.6 but no age-specific marital fertility breakup was given in the
final report. The estimate of MTFR was calculated again by inflating it
with the proportion of currently married women reported in Table 5.3a.
[PFFPS Final Report (1998)]. (2) The MTFR estimate of 7.9 from the
PFFPS-96 survey depicted a constant level of natural marital fertility
that is theoretically and empirically consistent with the experience of
other countries (Table 4). The finding of Sathar and Casterline (1998),
that decline in marital fertility has begun in Pakistan, is not
supported by the data. It is very surprising to note that the finding on
decline in marital fertility in Sathar and Casterline (1998) paper was
not based on any empirical evidence on the levels of MTFR in Pakistan
from different surveys.
The levels of contraceptive use at the later age groups, especially
at 35 and onwards, were not sufficient to produce an impact on marital
fertility (Table 5). The desired fertility transition witnessed in TFR
would reflect through the MTFR when higher levels of parity-specific use
of modern methods are reached in Pakistan.
SOCIOECONOMIC CONDITIONS IN 1990s
The Government policies relating to social sector and overall
restructuring of the economy were initiated during the fiscal year
1987-88 with the introduction of an economic austerity strategy which is
being implemented through Structural Adjustment Programme (SAP): This
has resulted in increased poverty levels both in urban and rural areas,
produced a high unemployment rate as a result of privatisation of the
economy, downsizing in the banking sector and other labour-intensive
projects, and reduction in remittances, coupled with a high inflation
rate that surfaced in early 1990s and virtually slowed down the entire
economy [Mahmood (1998)]. The experience of Pakistan and other countries
with SAP suggests that "structural adjustment programmes in some
countries in terms of better growth performance and improved
balance-of-payments position ... have been politically unpopular because
they result in aggravation of inequalities in society, enhance
unemployment and disproportionately hurt the lower and middle-income
groups" [Khan (2000)].
According to recent estimates, poverty has risen by 88 percent
since 1987-88, raising the number of poverty-stricken people from 17.8
million in 1987-88 to 43.9 in 1998-99 [Economic Survey (2000)]. The
slow-down of economy during these years produced shocks at the household
level by altering the available household resources through relative
changes in income and the price of goods and services that the household
consumed. The economic restructuring, therefore, altered the cost
structure of the household as a result of market responses, which also
affected, among other costs, the cost of raising children both in terms
of direct cost and opportunity cost of time to women.
It has been observed that the delay in marriages does not show any
differentials by education: "It is hard to conclude using
cross-sectional data that rise in age at marriage is caused by pursuit
of educational opportunities particularly because it is occurring even
among uneducated people" [Sathar and Kiani (1998)]. The
differentiating factor appears to be that economic hardship ensued with
the SAP and influenced the marriage rate downwards, where the normal
effect of socioeconomic variables disappeared among all the population
strata.
The neighbouring Sri Lanka underwent a similar demographic
situation in the 1970s to that which Pakistan appears to have been
experiencing since early 1990s. Economic hardships influence demographic
variables, as has been pointed out by De Silva (1990): "Marriages
were delayed as a result of economic hardship or increased mortality to
the mid-1970s, but once the overall economy improved after 1977, more
marriages took place". Namboodri (1983) observed that, initially,
it was the rising age at marriage that caused the total fertility rate
(TFR) to fall. The rising trend in marriage age in Sri Lanka stalled in
the latter half of the 1970s and at about the same time the TFR levelled
off and even began to show signs of going up.
It was found that the proportion of females remaining single at age
groups 15-19 and 20-24 rose from 45 to 79 percent and from 18 to 39
percent, respectively, from 1951 to 1998 (Table 6). The proportion of
persons remaining single revealed changes for men except for the age
group of 15-19. Sathar and Kiani (1998) observed that females were
experiencing more changes in marriage patterns than men. This new
pattern of delay in the onset of reproduction is a result of the
prevailing economic conditions that have led to unemployment coupled by
increasing inflation rates. This is consistent with the theoretical work
of Malthus who proposed the homeostasis hypothesis, that the
reproduction responded positively when there were increases in real
wages, which promote marriage rates and fertility and a decline in
mortality. Economic prosperity historically influences marriage patterns
and fertility if family planning is not widely practised, as is the case
in Pakistan.
Simmons, while describing the Malthusian theory of fertility,
states it even more directly: "When the economic conditions of
young unmarried individuals are favourable, they marry relatively early,
and the fertility is high. When economic conditions are less
advantageous, the age at marriage rises and fertility declines".
[Simmons (1985).]
Another factor to be considered is that female labour force
participation increased in Pakistan after the introduction of the SAP.
(Table 7). The economic restructuring may modify capacity of labour
force absorption by sex in various industries of the economy, and has an
impact on the opportunity cost of women's time for the bearing and
rearing of children. One of the major indicators of women's
economic status is the female labour force participation. During the
restructuring of the economy, which emphasises on privatisation and
downsizing, men tended to lose jobs and more women were likely to go to
the labour market to make up for the lost household income [Encarnacion
(1974)].
The past research, using data from PFS-75, PLM-81, and afterwards,
has explored the complex inverse relationship between female labour
force participation and fertility. This debate has largely remained
inconclusive due to lack of appropriate information that could be linked
to the wage and non-wage labour force participation and fertility,
including also the relationship between the labour force participation
and fertility and the employment experience of women before and after
marriage.
In the case of Pakistan, female employment as measured by the
simple indicator of having worked or not worked before the survey proved
to be a very significant determinant of recent fertility levels
[Rodriguez and Cleland (1981)]. The new trend in labour force
participation probably depicts the worsening situation of the economy,
by creating employment that probably hurt relatively more males while
opening up opportunities for females to look for a job. This scenario
reveals a trend of closure of the job opportunities rather than growth
for both the sexes in Pakistan until the year 1995. The reported
unemployment rate among the females was 17 percent in the year 1996,
which was indicative of the fact that the economy was not able to create
jobs especially for females [Appendix Table A 2]. [Labour Force Survey
(1996-97)].
The economic shock in the shape of the Structural Adjustment
Programme (SAP) produced an impact at the household level. The data from
Census-1998 and the surveys have pointed towards changes in marriage
rates, fertility, and use of contraception. Economic hardships slowed
down the marriage rates as revealed in the reported increased number of
never-married persons by gender, place of residence, and level of
education. The increased poverty level resulted in the rise of the cost
of children. The sustained decline in fertility, threefold increase in
contraception use by men, and choice of the most effective contraceptive
methods which provided longer duration of protection against pregnancy
are indicative of a changed approach towards the reproductive process.
The combined effect of the economic factors may produce a major impact
on the fertility level in Pakistan.
It was expected that after the downturn of the economy, women and
children, the particularly vulnerable section of the society, would
suffer the most to bear the fallout of economic hardships. As the census
data point to an improvement in the survivorship of females, and other
data sources also confirm an increase in female life expectancy and
increased female level of labour force participation, these changes are
indicative of the fact that the reversed economic situation probably
helped females in terms of the rise in their economic status and
empowerment at the household level decision-making. However, these
demographic effects appear to be provisional, and the real effects may
further deepen, as the economy has not yet recovered from the state of
recession.
CONCLUSION
The onset of fertility transition, which apparently was witnessed
in the year 1984, appears continuous in the surveys that followed
afterwards. The reported decline in TFR was approximately 15 percent
until the year 1996 in comparison to the fertility levels revealed in
1975. The decomposition of proximate determinants reveals that fertility
decline occurred largely on account of the rise in age at marriage and
also due to the decline in breastfeeding. The research finding of Sathar
and Casterline (1998), that contraception played a significant role in
the fertility transition in Pakistan, is not supported by the data. The
contribution of contraception was found to be the lowest in the decline
of fertility. The mean duration of breastfeeding levels declined by
three months in 1996 from the levels revealed in 1991. The declining
effect of breastfeeding was most probably due to the reported rising
female education, which increased fivefold over the levels found in the
1981 Census [The Mahbubul Haq Human Development Centre (2000)]. The
other factor responsible for the decline in breastfeeding, as suggested
by the research findings elsewhere [Jain and Bongaarts (1981)], is the
process of urbanisation, which increased from 28.1 to 32.5 percent--an
upwards change in urbanisation by 16 percent from the levels found in
the Population Census, 1981. The slight overestimation of indirect
change in fertility over the observed one is further evidence that
breastfeeding declined was more than 10 percent in magnitude than the
levels found in 1991.
The transition witnessed in the TFR did not start in the MTFR and
it remained constant between 1991 and 1997; thus the claim for marital
decline by Sathar and Casterline (1998) does not hold. It will take a
higher level of prevalence for the transition to shift towards a
regulated fertility after a visible decline takes place in marital
fertility, as has been demonstrated in the research done by Bongaarts
(1984).
The use of contraceptives increased twofold mostly in the 1990s,
from 12 percent in 1990 to almost 24 percent in 1996. The increase in
the proportion of never-married also went up during the intercensal
period without the influence of socio-economic factors, as revealed in
the Population Census, 1998. The focal point of the 1990s in the
fertility transition indicates a major influencing factor in operation,
the Structural Adjustment Programme, which was introduced in Pakistan in
the late 1980s and had wide-ranging social and demographic effects. It
caused an increase in the poverty levels both in the urban and the rural
areas of the country, rise in unemployment due to privatisation of the
economy, downsizing in banking and in other large labour-intensive
projects, coupled with a decline in remittances and increasing levels of
inflation during the 1990s. The real income of households apparently was
affected as the poverty levels have been increasing since 1987-88.
The poverty-inducing adverse effects of the Structural Adjustment
Programme are probably responsible for a change in demographic
parameters, especially of the marriage rates, which influenced a decline
in fertility while contraceptive prevalence levels remained almost
constant. This is theoretically consistent with the macro theory of
fertility. There is historically consistent proof, ranging from Malthus
to Neo-Malthusian schools of thought, that the economic conditions
influenced the marriage rates heavily. The apparent decline in fertility
in Pakistan was largely due to the rise in the age at marriage. However,
this rise appears to be transitory. Once the economic conditions improve
and prosperity returns, there is a likelihood that the effect of
marriages on fertility transition may show an opposite trend if the
desired fertility transition is not witnessed in marital fertility.
Improvement in the quality of service delivery in family planning
clinics, restructuring of the decision-making process which is
responsive to the local marketing needs, and training and motivation of
the personnel appear to be the factors that need to strengthened to
arrest the effects of economy-led positive demographic benefits in the
fertility transition.

(1) The mean duration of breasffeeding reported in the PFFPS-96 was
higher than the levels found in the PFS-75 and a different methodology
was used as against that in the previous surveys. However, the mean
duration of 22.5 months of breastfeeding revealed in the PFPPS-96
appears to be on the higher side when compared to a declining trend
indicated from the levels found in the previous two surveys, the PFS75
and the DHS-91 (Table 8). The estimate of mean duration included those
children who were ever-breastfed but did not include those children who
were never-breastfed, and this drawback was removed from the new
estimate of the mean duration. For further details, refer to Sara
Miller, "Trends in Breastfeeding in a Dozen Developing
Countries", International Family Planning Perspectives, 12:3
(September, 1986). Moreover, the estimate contained a methodological
drawback of not being compatible with the similar estimates obtained
from the previous surveys. [PFFPS Report (1998)].
(2) The age-specific marital fertility rates were calculated by
inflating the age-specific fertility rates g(a) by the proportion of
currently-married women. The age-specific marital fertility for the
first group g(15-19) was estimated as 0.75 g(20-24). The TMFR appeared
to be 7.9, slightly higher than the figure of 7.6 reported in the first
report. The MTFR figure in the survey was reported but no age break-up
was given [PFFPS Report (1998), Tables 53a and 6.4b].
(3) The Population Growth Estimation (PGE) Experiment contained a
dual record type capturing of the vital events in a longitudinal
registration (TMFR 7.9) and cross-sectional surveys from 1962-65. The
Chandra-Deming theoretical estimate (TMFR 10.2) was also calculated
through a matching of events by application of the probability theory.
The average of the longitudinal registration and Chandra-Deming method
revealed the TFR figure of 9.1.
(4) The Structural Adjustment Programme (SAP), suggested jointly by
the World Bank and the International Monetary Fund to Pakistan, that was
started from the fiscal year 1987-88 meant that the country's
economic performance would be evaluated on the basis four components
which included the rate of real Gross Domestic Product (GDP) growth, the
ratio of domestic savings to GDP, the ratio of domestic investments to
GDP, and the ratio of exports to GDP. There were five basic
conditionalities which were attached to the SAP that included the
abolition or liberalisation of foreign exchange and import controls,
devaluation of the currency, a strong anti-inflation programme by
controlling wage and salary increases, dismantling of price controls,
greater opening up of the economy to international commerce, and
privatisation of the public sector. For details, refer to Khan (2000).
