{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.
