Regional and State Projections of Income, Employment, and Population
to the Year 2000
THIS article presents regional and State projections to 2000 of
total personal income (TPI), earnings and employment for 13 industries,
and population, based on data through 1983. An article in the November
1980 SURVEY OF CURRENT BUSINESS presented projections of these measures
to 2000, based on data through 1978.
These projections are based on an extension of past economic
relationships and assume no major policy changes. They are neither
goals for, nor limits on, future economic activity in any region or
State. These projections have three major uses: (1) Assessing future
demand for goods and services by households, businesses, and government,
(2) foreseeing future economic problems so that corrective policies can
be adopted, and (3) providing a "baseline' for measuring the
effects of a policy by modifying the projections to reflect the policy
and comparing the modified projections with the initial projections.
The first part of this article discusses projected trends to the
year 2000 in TPI, population, per capita personal income, and earnings
by industry for the United States, regions, and States. The second part
discusses projection methodology.
Projected Trends, 1983-2000
United States
For the United States, TPI (expressed in 1972 dollars) is projected
to grow 2.6 percent per year in 1983-2000; population, 0.8 percent; and
per capita personal income (expressed in 1972 dollars), 1.8 percent.
The growth rates in TPI and in per capita personal income will be more
than the corresponding rates in 1973-83, and the growth rate in
population will be less than the 1973-83 rate. The projected
acceleration in TPI mainly reflects a large acceleration in
earnings--that is, labor income, consisting of wage and salary
disbursements and other labor income, and proprietors' income.
Earnings (expressed in 1972 dollars), the largest component of TPI,
is projected to grow 2.9 percent per year. Major industries in which
the earnings growth rate will exceed the all-industry earnings growth
rate are services; finance-insurance-real estate;
transportation-communication-public utilities; mining; construction; and
durables manufacturing (chart 8). In the first four industries,
earnings grew at above-average rates in 1973-83. In construction and
durables manufacturing, in contrast, earnings grew at below-average
rates. The projected shift in construction earnings occurs in part
because demand for new structures is projected to return to its
long-term growth path. The projected shift in durables manufacturing
earnings reflects the national defense buildup. In durables
manufacturing, earnings will grow at well-above-average rates in
instruments, machinery, fabricated metals, and transportation equipment.
Major industries in which the earnings growth rate will fall short
of the all-industry rate are Federal government, nondurables
manufacturing (in particular, leather, textiles, apparel, and food
processing), retail trade, farming, State and local government, and
wholesale trade. In the first four industries, earnings also grew at
below-average rates in 1973-83. In State and local government and in
wholesale trade, in contrast, earnings grew at above-average rates. The
projected shift in State and local government earnings reflects
taxpayers' continuing concern for limiting State and local
government expenditures.
In the two following sections, the United States is divided into
two regional groupings, fast growing and slow growing, based on the
projected average annual growth rate in TPI. For each grouping,
projected trends relative to the U.S. average in TPI, population, and
per capita personal income are summarized. For the regions and States
within each grouping, projected trends relative to the U.S. average in
TPI, per capita personal income, and earnings by industry are
summarized.
Fast-growing regions
In 1983-2000, each of four southern and western regions (Rocky
Mountain, Southwest, Far West, and Southeast), as well as the New
England region, is projected to have a growth advantage (that is, an
index based on the ratio of growth in the region to growth in the United
States is more than 100) in TPI and population (table 1). In 1973-83,
each southern and western region had a larger advantage in each measure;
New England, in contrast, had a growth disadvantage (that is, an index
based on the ratio of growth in the region to growth in the United
States is less than 100) in each measure in 1973-83.
For each southern and western region, the projected TPI advantage
is a continuation, at a dampened rate, of a tendency for manufacturing
and related private service-type industries to disperse to the South and
West to benefit from relatively low wage rates, energy and land costs,
and State and local taxes. The population advantage is based on an
advantage in employment and a continuation, at a dampened rate, of a
tendency for workers and retirees to migrate from the North to the South
and West. For New England, the projected TPI and population advantages
reflect a continuation of a recent trend toward rapid job growth in
"high-technology' manufacturing and in related research and
development services; in part, the rapid growth is a response to the
national defense buildup.
In each of the five regions, per capita personal income is
projected to converge toward the U.S. average (chart 9). In the Rocky
Mountain, Southwest, and Southeast regions, per capita personal income,
which was below the U.S. average in 1983, is projected to increase
faster than in the United States. In the Far West and New England, per
capita personal income, which was above the U.S. average in 1983, is
projected to increase more slowly than in the United States.
Rocky Mountain.--Each State will have a growth advantage in TPI;
growth per year will range from 3.8 percent in Utah to 2.7 percent in
Montana (table 2 and chart 10). In 2000, the region's per capita
personal income is projected to be 96 percent of the U.S. average; per
capita income will continue to be below the U.S. average in Utah, Idaho,
and Montana and above the average in Wyoming and Colorado (table 3).
The region's projected growth advantage in TPI reflects
earnings advantages in all of the major industries that are projected to
grow relatively rapidly nationwide (tables 4 and 5). In mining,
advantages in oil and gas extraction, particularly in Wyoming and
Colorado, and coal mining, particularly in Wyoming, reflect the
Nation's dependence on this region for part of its long-term energy
supply. In durables manufacturing, advantages in technologically
advanced machinery, transportation equipment, fabricated metals, and
instruments reflect a continuation of the region's rapid
industrialization, particularly in Utah and Colorado. In services and
in the transportation and finance groups, advantages reflect the
increasing self-sufficiency of the region in supplying these services.
Southwest.--Each State will have a growth advantage in TPI; growth
per year will range from 4.3 percent in Arizona to 2.6 percent in
Oklahoma. In 2000, the region's per capita personal income is
projected to be 98 percent of the U.S. average; per capita income will
be below the U.S. average in each Southwest State except Texas, where it
will equal the average.
The region's projected growth advantage in TPI reflects
earnings advantages in most fast-growing major industries. In durables
manufacturing, advantages in machinery, instruments, fabricated metals,
and aerospace equipment reflect the regional effects of the national
defense buildup, particularly in Texas. In services and in the
transportation and finance groups, advantages reflect both the rapid
growth of manufacturing and a continuation of rapid growth in population
--in particular, in the number of retirees who migrate to Arizona. In
mining, despite an advantage in oil and gas extraction in 1973-83, no
advantage is projected, as competing energy sources in other regions are
increasingly developed.
Far West.--Each State will have a growth advantage in TPI; growth
per year will range from 3.9 percent in Nevada to 2.8 percent in
California. In 2000, the region's per capita personal income is
projected to be 107 percent of the U.S. average; per capita income will
be above the U.S. average in each Far West State except Oregon.
The region's projected growth advantage in TPI reflects
earnings advantages in nearly all fast-growing major industries. In
durables manufacturing, advantages in technologically advanced
equipment--such as scientific instruments, computing equipment, and
aerospace equipment --reflect the regional effects of the national
defense buildup, particularly in California and Washington. An
advantage in plastics, which is the only nondurables manufacturing
industry that is projected to grow rapidly nationwide, also reflects the
buildup. An advantage in business services reflects strong demand by
the technologically advanced industries for research and development,
consulting, and data processing services. Advantages in hotels and
amusement-recreation services reflect continuing strength in tourism,
particularly in Nevada. An advantage in health services reflects the
region's rapid population growth.
Southeast.--Each State, except West Virginia, Kentucky, Alabama,
and Virginia, will have a growth advantage in TPI; growth per year will
range from 3.5 percent in Florida to 2.1 percent in West Virginia. In
2000, the region's per capita personal income is projected to be 90
percent of the U.S. average; per capita income will be below the U.S.
average in each Southeast State except Virginia.
The region's projected growth advantage in TPI reflects
earnings advantages in nearly all fast-growing major industries. In
durables manufacturing, advantages in both fabricated metals and
machinery--particularly in North Carolina, South Carolina, and
Mississippi--and an advantage in transportation equipment-- particularly
in Mississippi, Louisiana, and Florida--reflect the national defense
buildup. Advantages in construction and related financial and real
estate services reflect strength in manufacturing, as well as a
continuation of rapid growth in population-- in particular, in the
number of retirees who migrate to Florida. Advantages in
amusement-recreation services and air transportation reflect strength in
tourism, again particularly in Florida. In mining, in contrast, a
disadvantage reflects a loss of competitive position in coal production,
particularly in West Virginia and Kentucky.
New England.--Each State except Maine and Rhode Island will have a
growth advantage in TPI; growth per year will range from 3.1 percent in
New Hampshire to 2.3 percent in Maine. In 2000, the region's per
capita personal income is projected to be 110 percent of the U.S.
average; per capita income will be above the U.S. average in
Connecticut, Massachusetts, and New Hampshire, and below the U.S.
average in Maine, Vermont, and Rhode Island.
The region's projected growth advantage in TPI reflects
earnings advantages, or earnings growth near the U.S. average, in most
fast-growing major industries. In durables manufacturing, advantages in
electronic and computing equipment in part reflect a continuing
resurgence in the industrial application of technological innovations
developed at major New England universities and in part reflect the
national defense buildup. In construction, earnings growth near the
U.S. average reflects strength in manufacturers' demand for new
structures. Growth near the U.S. average in business services reflects
strength in manufacturers' demand for research and development and
data processing services. Growth near the U.S. average in insurance
reflects a continuation of New England's long-standing role of
providing this service to other regions.
Slow-growing regions
In 1983-2000, each of three northern and central regions (Plains,
Great Lakes, and Mideast) is projected to have a growth disadvantage in
TPI and population. In 1973-83, each region had a larger disadvantage
in each measure. The TPI disadvantage projected for the northern and
central regions is a continuation, at a dampened rate, of weakness in
manufacturing in the Nation's oldest manufacturing centers, which
will continue to be adversely affected by industrial shakeout. The
population disadvantage is based on a disadvantage in employment and a
continuation, at a dampened rate, of the migration of workers and
retirees to the South and West.
In each of the three regions, per capita personal income is
projected to converge toward the U.S. average. In the Plains and Great
Lakes regions, per capita personal income, which was below the U.S.
average in 1983, is projected to increase faster than in the United
States. In the Mideast, per capita personal income, which was above the
U.S. average in 1983, is projected to increase more slowly than in the
United States.
Plains.--Each State except Minnesota will have a growth
disadvantage in TPI; growth per year will range from 2.7 percent in
Minnesota to 2.2 percent in Iowa. In 2000, the region's per capita
personal income is projected to be 99 percent of the U.S. average; per
capita income will be below the U.S. average in each Plains State except
Kansas and Minnesota.
The region's projected growth disadvantage in TPI reflects
earnings disadvantages in manufacturing and service-type industries. In
addition, farming, which accounts for a larger share of earnings in the
Plains than in any other region, will contribute to the region's
overall disadvantage. In manufacturing, a disadvantage in food
processing reflects the close relationship of earnings in this industry
to farm earnings. Among service-type industries, disadvantages occur in
the wholesaling and trucking of agricultural commodities.
Great Lakes.--Each State will have a growth disadvantage in TPI;
growth per year will range from 2.4 percent in Indiana to 1.9 percent in
Illinois. In 2000, the region's per capita personal income is
projected to equal the U.S. average; per capita income will be above the
U.S. average in Illinois and Michigan and below the U.S. average in
Indiana, Wisconsin, and Ohio.
The region's projected growth disadvantage in TPI reflects
earnings disadvantages in most major industries. In durables
manufacturing, disadvantages, particularly in Michigan and Ohio, in the
motor vehicles industry and in industries that supply inputs to it, such
as primary and fabricated metals and machinery, reflect a continuation
of a tendency for durables firms to choose lower cost locations in
nearby Southeast States. In nondurables manufacturing, a disadvantage
in rubber tire manufacturing reflects its role as a supplier to the
motor vehicles industry. In construction, trans-portation, trade, and
services, disadvantages reflect weakness in manufacturing and a rate of
population growth that is projected to be slower than in any other
region.
Mideast.--Each State will have a growth disadvantage in TPI; growth
per year will range from 2.5 percent in New Jersey to 1.9 percent in
Pennsylvania. In 2000, the region's per capita personal income is
projected to be 107 percent of the U.S. average; per capita income will
be above the U.S. average in each Mideast State except Pennsylvania.
The region's projected growth disadvantage in TPI reflects
earnings disadvantages in all major industries. In manufacturings,
disadvantages in apparel, particularly in New York and Pennsylvania, and
primary metals, particularly in Pennsylvania and Maryland, reflect a
continuation of a tendency for manufacturers to choose sites near
rapidly growing markets in the South and West, at the expense of
traditional production sites in the Mideast. In wholesale trade, a
disadvantage reflects the continuing decline of the New York
metropolitan area, relative to southern and western areas like Miami and
Los Angeles, as a center for international trade. In construction and
most service industries, disadvantages reflect weakness in manufacturing
and slow growth in population.
Projection Methodology
The methodology underlying the projections presented in this
article is similar to that discussed in the 1980 article. The national
projections are based mainly on the work of the Bureau of Labor
Statistics (BLS) in order to take advantage of that agency's
expertise in making detailed national projections of employment by
industry. The State projections of total employment and earnings are
based on detailed projections for 57 industries.
The projections are made in two major steps--for the Nation, and
then for the States. (Projections for each BEA region are the sum of
the projections for each State in the region.) In the national step,
GNP is projected, based on projections of population, labor force,
employment, and productivity. TPI and total earnings are projected
based on GNP. Then, employment and earnings by industry are projected.
In the State step, employment and earnings by industry are
projected within the framework of the corresponding projected national
totals by industry. Moreover, employment and earnings by industry are
projected so as to ensure interindustry consistency in earnings per
employee within each State. Then, population is projected, based on
projections of total employment. Finally, nonearnings components of TPI
are projected, based on projections of population and total earnings.
The State projections are developed within a framwork of national
totals, rather than independently for each State, because the historical
measures on which the projections are based are more reliable and stable
for larger areas.
National projections
GNP.--GNP projections (expressed in 1972 dollars) are made by
multiplying projected total employment, on a job-count basis, by
projected GNP per employee. Projections of job-count employment are
based mainly on projections of (1) population, in particular, the
civilian noninstitutional adult population, (2) labor force, and (3)
employment, on a persons-employed basis.
Projections of total population are from the Census Bureau's
middle series of national projections. This series assumes that in 2000
the completed fertility rate will be 1,960 births per 1,000 women and
that life expectancy at birth will be 76.7 years. The series assumes
that net immigration will be 450,000 persons per year. Projections of
the civilian noninstitutional adult population, a subset of total
population, are mainly from BLS.
Labor force projections, also mainly from BLS, are made by first
projecting labor force participation rates, by age and sex, and then
applying these rates to the civilian noninstitutional adult population.
BLS projections of civilian unemployment rates are 6.3 percent in 1990
and 6.0 percent in 1995; BEA's extension of the BLS trend yields an
unemployment rate of 5.7 percent in 2000.
Projections of employment, on a persons-employed basis, are made by
subtracting unemployment from labor force. Projections of job-count
employment are equal to projected employment, on a persons-employed
basis, increased by the projected percentage of workers who hold more
than one job.
Projections of GNP per employee are derived in three steps from BLS
projections. First, BLS projections of GNP (based on trends through
1982) in 1990 and 1995 are increased by 2 percent to reflect the
stronger-than-average recovery in productivity growth from 1982 to 1983.
Second, the resulting GNP projections are divided by job-count
employment, already projected, to obtain GNP per employee in 1990 and
1995. Third, the resulting 1990-95 growth in GNP per employee (5.8
percent) is assumed to prevail in 1995-2000, in order to obtain GNP per
employee in 2000. As noted earlier, projections of GNP are the product
of projected GNP per employee and projected job-count employment.
Personal income.--Because methodologies for estimating gross
product of States are still in a developmental stage, the GNP projection
must be translated into some other measure for States.1 The measure
chosen is TPI, the most comprehensive measure of regional economic
activity currently available.
1. A forthcoming BEA Staff Paper, "Experimental Estimates of
Gross State Product by Industry,' discusses sources, methods, and
potential applications for a set of experimental estimates of gross
product by industry for States.
TPI consists of earnings, less personal contributions for social
insurance, plus rental income of persons, personal dividend income,
personal interest income, and transfer payments. Each component of TPI
is projected, based on the trend in the ratio of the component to a
national total that already was projected.
Earnings, the largest component of TPI, is projected to be 60.0
percent of GNP in both 1990 and 2000. Personal contributions for social
insurance is projected to be 6.8 percent of earnings in 1990 and 7.6
percent in 2000. Rental income of persons and personal dividend income
are projected to be 3.7 percent of GNP in both 1990 and 2000. Personal
interest income is projected to decline to 10.4 percent of GNP in 1990
and to 9.8 percent in 2000.
Transfer payments are projected in two parts. The larger
part--payments made under old-age, survivors', disability, and
health insurance programs (OASDHI) and under government employee
retirement programs --is projected relative to the population aged 65
and over; these payments, per person aged 65 and over, are projected to
be 84.0 percent of per capita personal income in both 1990 and 2000.
All other transfer payments are projected to decline to 4.5 percent of
earnings in 1990 and to 4.3 percent in 2000.
Employment and earnings by industry. --National projections of
employment by industry are mainly from BLS. Adjustments are made to
reflect the projections of total employment (discussed above) and more
recent historical data. Projections of earnings by industry are made
primarily by projecting the ratios of earnings to employment and
applying these ratios to employment by industry.
State projections
The State projections are prepared using the following procedure.
First, employment and earnings by industry are projected using models of
economic relationships within each State and between each State and the
Nation. Then, population is projected to be consistent with projected
total employment. Finally, the nonearnings components of TPI are
projected to be consistent with projected total earnings and population,
and then are added to total earnings to yield projected TPI.
Each part of the State projections procedure has two phases. In
the first phase, preliminary projections are generated based on
mathematical relationships among variables. In the second phase, the
preliminary projections are reviewed and, when necessary, are modified
to reflect State-specific economic trends and events that are not easily
reflected in mathematical relationships.
Employment and earnings by industry. --Preliminary projections of
State employment by industry are made using a mathematical model of
economic growth. In each State, growth of employment in each industry
is projected based on (1) projected growth of total employment in the
industry nationally (discussed earlier) and (2) projections of the ratio
of total employment in the industry in the State to the employment
required to meet intrastate demand for the industry's products.
The ratio is assumed to reflect the State's competitive position in
the industry; if the ratio exceeds (is less than) unity, the State is
assumed to have a competitive advantage (disadvantage) in the industry,
relative to other States.
Estimation of the ratios requires extensive data on interindustry
patterns of sales and purchases in each State. These data generally are
unavailable; accordingly, national relationships-- based on unpublished
BLS input-output data--are used to estimate the ratios for each industry
in each State, 1969-83. Growth rates of the ratios then are estimated
using ordinary least-squares regression techniques. The resulting
growth rates, somewhat dampened, are used to project the ratios to 2000.
Projections of national employment by industry and national input-output
relationships, along with the projected ratios, then are used to project
employment by industry in each State, 1984-2000.
Preliminary projections of State earnings by industry are made as
follows: (1) The historical trend in State earnings per employee in an
industry is projected as a percent of national earnings per employee in
the corresponding industry, (2) this measure is multiplied by national
earnings per employee in the industry--already projected--to yield
projected State earnings per employee in the industry, and (3) this
product is multiplied by projected State employment in the industry to
yield projected State earnings in the industry.
The preliminary projections of State employment and earnings by
industry are reviewed and, when necessary, are modified within a
"basic-service' framework. In a basic-service framework, each
of a State's industries is classified as basic or service. Basic
industries are those that produce products that are generally
exportable. The composition of a State's basic industries depends
primarily on the State's relative endowment of the inputs required
in the production process. The relative endowment of these inputs
determines the State's relative advantage, compared with other
States, in producing the output of its basic industries. States export
products for which they have a relative advantage in production and
import other products. In general, farming, mining, manufacturing, the
Federal military, and railroad, pipeline, and water transportation are
classified as basic industries in all States because the bulk of their
output is directed at broad, often national, markets. Certain services,
such as hotels in Nevada, also are treated as basic industries in some
States because more of their employment and earnings derives from
consumers from other States than from local businesses and households.
A State's service industries derive employment and earnings
mainly from purchases by businesses and households within the State. In
general, construction, certain modes of transportation, communication,
public utilities, trade, finance, insurance, real estate, business and
professional services, and civilian government are classified as service
industries in most States.
A State's total growth mainly depends on the stimulus provided
by its basic industries. The basic industries grow in response to
increases in the demand for their output by other States. Increased
exports generate additional employment and earnings, which stimulate
service-industry growth in the exporting State.
Use of a basic-service framework to modify the preliminary State
projections of employment (earnings) by industry requires the following
data: (1) National projections (from the national step of the
projection methodology) of employment (earnings) by industry, (2) the
classification of each of a State's industries as basic or service,
(3) for each basic industry in each State, preliminary projections of
the State's share of employment (earnings) in the corresponding
industry nationally, and (4) for each service industry in each State,
preliminary projections of the industry's location quotient (LQ),
that is, the ratio of the industry's share of State total
employment (earnings) to the industry's share of national total
employment (earnings).
With these data, State employment (earnings) by industry can be
projected in a basic-service framework. (The basic-service projections
will differ from the preliminary projections when data items 3 and 4
require modification; conditions under which modification is necessary
are discussed later.) The equations that follow summarize the
basic-service projection framework. In the equations, E(ij) is
employment (earnings) in industry i in State j, E.(j) is total
employment (earnings) in State j, E(i). is total employment (earnings)
in industry i in the Nation, and E.. is total employment (earnings) in
the Nation. Given the national projections (data item 1) and the
projected basic-industry shares (data item 3 above, hereafter denoted as
S(ij)), E(ij)--employment (earnings) in a State--for each basic industry
can be computed directly as:
(1) E(ij) = S(ij) E(i).
Total State employment (earnings)-- the sum of basic- and
service-industry employment (earnings)--can be expressed as:
(2) E.(j) = E(ij) E(ij)
i=basics i=services
The first term on the right of equation (2)--total basic-industry
employment (earnings) in a State--can be obtained directly from the
results of equation (1). The second term--total service-industry
employment (earnings) in a State--can be obtained indirectly, by using
the definition of the service-industry LQ (data item 4 above) to derive,
for each service industry:
(3) E(ij)=E.(j)(E(i)./E..)LQ(ij)
Denoting total basic-industry employment (earnings) as B.(j), and
incorporating equation (3) in equation (2), yields:
(4) E.(j)=B.(j) E.(j) (E(i)./E..)LQ(ij)
i=services
Inasmuch as the LQ's and the national totals are given, the
sum in equation (4) can be computed. Denoting this sum as M.(j), the
solution of equation (4) for E.(j) yields:
(5) E.(j) = B.(j)/1-M.(j)
To complete the solution of the system of equations, employment
(earnings) for individual service industries can be computed directly
from equation (3), based on the solution for the State's total
employment (earnings) from equation (5).
In each State, each basic-industry share, derived from the
preliminary projections, is modified, when necessary, to reflect the
assumption that factors that affected the share historically will
continue to affect it in the future, but less strongly, so that in all
cases the projected rate of change in share decelerates. This
assumption ensures that no industry in a State will be projected to have
an unreasonably large or small share of national employment (earnings)
in the industry; that is, equilibrating forces at work in the State
economies will tend in the long run to reduce State-to-State differences
in growth rates for an industry. In some cases, the projected share is
further modified to take into account economic developments that are not
yet reflected in the historical data.
In each State, each service-industry LQ, derived from the
preliminary projections, is modified, when necessary, to ensure that
historical trends are properly reflected. In most cases, continuation
of the historical trend results in the convergence of the projected LQ
toward unity. However, if the LQ is diverging from unity historically,
the historical trend is dampened or reversed in the projection period.
In no case is a projected service-industry LQ permitted to change from a
value more than unity to a value substantially less than unity, or vice
versa. As with basic-industry shares, the projected service-industry
LQ's are modified to take into account economic developments that
are not yet reflected in the historical data.
The review and adjustment phase of the procedure for projecting
State employment and earnings by industry is lengthy. Following
adjustments to ensure consistency with the general criteria noted above,
the basic-service projections are reviewed to ensure consistency in both
the projected industrial distribution of each State's economy and
the projected State distribution of each of the Nation's
industries. The resulting projections then are provided to State
government agencies for further review; BEA makes the projections final
only after this review.
Population and personal income.-- State population projections are
based on the assumption that interstate migration of the working-age
population is mainly determined by economic opportunity; job-count
employment is used as the indicator of economic opportunity. Population
is projected for three major groups: labor pool (ages 15-64), prelabor
pool (ages 0-14), and postlabor pool (ages 65 and over).
In each State, the labor pool population is projected as follows:
(1) The historical trend in the labor pool population/ employment ratio
in the State is projected as a percent of the corresponding ratio in the
Nation, (2) this measure is multiplied by the labor pool
population/employment ratio in the Nation--already projected --to yield
the projected labor pool population/employment ratio in the State, and
(3) this product is multiplied by State employment--already
projected--to yield the labor pool population in the State.
The prelabor pool population is projected based on the population
projection for the parent age group (that is, the labor pool
population). The postlabor pool population is projected based on each
State's historical pattern of inmigration or outmigration for this
age group.
In general, the nonearnings components of TPI for each State are
based on State projections of total earnings and population, within the
framework of the national projections for the nonearnings components.
Projected TPI is the sum of the projected earnings and nonearnings
components.
