ABSTRACT

 Projections of the Population of States, by Age, Sex and Race: 1988 to 2010
 {machine-readable data file} /prepared by the Bureau of the Census.
 - Washington: The Bureau of the Census {producer and distributor}, 1989.

 Type of File:

    Summary statistics.

 Universe Description:

    The universe is the resident population of the 50 states and the
    District of Columbia.

 Subject-Matter Description:

    This file contains annual projections of the resident population for the
    50 states and the District of Columbia by single years of age (age 0 to
    85 and over), sex (males and females), and race (white, black, and other
    races) for years 1986 through 2010.

    These projections utilize a mathematical projection model known as the
    cohort-component method. This method permits separate assumptions to be
    made for each of the components of population change:  births, deaths,
    internal migration and international migration.

    The projections are consistent with the July 1,1986 population estimates
    for States. In general, these projections assume a slight increase in
    the national levels of fertility to an ultimate level of 1.8 births per
    woman. For mortality', these projections assume that the overall level
    of life expectancy increases from 75.0 in 1986 to 77.6 in 2005 and 81.2
    in 2080. The projections assume a decreasing level of net international
    migration from an annual level of 600,000 through 1988 to 500,000 by
    1998. Internal migration assumptions in these projections are based on
    the annual state-to-state migration data for the 1975-86 period.
INTRODUCTION

 PROJECTIONS OF THE POPULATION OF STATES,BY AGE, SEX, AND RACE: 
  1988 TO 2010

 This tape contains the Census Bureau's latest set of annual projections
 of the resident population for the 50 states and the District of Columbia
 by single years of age (age 0 to 85 and over), sex (males and females),
 and race (white, black, and other races) for years 1986 through 2010. A
 mathematical projection model known as the cohort-component method was
 utilized to produce these projections. This method permits separate
 assumptions to be made for each of the components of population change:
 births, deaths, internal migration, and international migration. These
 projections are consistent with the July 1,1986 population estimates for
 states. In general, these projections assume a slight increase in the
 national levels of fertility to an ultimate level of 1.8 births per woman
 and a continuation of the existing differentials in state age-specific
 birth rates. For mortality, these projections also assume that the existing
 patterns of state differentials in mortality remain unchanged while the
 overall level of life expectancy increases from 75.0 in 1986 to 77.6 in
 2005 and 81.2 in 2080.  A decreasing level of net international migration
 from an annual level of 600,000 through 1988 to 500,000 by 1998 is assumed.

 At the state level, internal migration is the most important and complex
 component of population changes. In general, it is also the component that
 shows the greatest degree of fluctuation. The present projections are the
 first to incorporate the annual state-to-state flows of migrants for the
 1975 through 1986 period developed from annual administrative data. These
 data are used in combination with decennial census migration data as a
 basis for projecting future migration. Although certain parts of the
 historical period examined (1975 through 1986) may represent unique
 circumstances in many of the states, the past does, in general, provide a
 basis for projecting the future. Undoubtedly, this set of projections does
 not imply certainty about the future course of events. Small and often
 unforeseeable changes in economic, social, or demographic conditions in any
 state can and will cause future population changes to deviate from the
 projected trends.

 The difference between these projections and forecasts is that they present
 only the results of the mathematical projection model given explicitly
 stated assumptions. The resulting projections represent a consistent
 methodology and a consistent set of assumptions that add to the projected
 national resident population. With this type of approach, the projections
 of one State can easily be compared to the projections of another State.

 The assumptions concerning future levels of fertility, mortality, and
 international migration are consistent with the middle series of the
 national population projections published as Current Population Reports,
 Series P-25, No. 1018. These projections are identical to the summary
 data included in the recent Census Bureau report, Current Population
 Reports, Series P-25, No. 1017.
