County-Specific Net Migration by Five-Year Age Groups, Hispanic Origin, Race, and Sex, 1990-2000: [United States] (ICPSR 4171)

Released/updated on: 2005-05-23

Geographic coverage: United States

Time period: 1990-01-01--2000-01-01

This data collection provides net migration estimates by five-year age groups, Hispanic origin, race, and sex for counties of the United States from 1990 to 2000. These estimates were derived from United States census data from 1990 to 2000, and from vital statistics collected by the National Center for Health Statistics (NCHS) for years 1990 through 1999 using the vital statistics (VS) method. The dataset contains the state and county Federal Information Processing Standards (FIPS) codes that uniquely identify counties within a state. Several data categories are presented in the collection. Vital statistics data tabulate births by sex, race, and Hispanic origin for the periods 1990-1994 and 1995-1999, and deaths by sex, race, Hispanic origin, and age groups for the period 1990-2000. The enumerated and adjusted 1990 and 2000 population categories offer population totals by sex, Hispanic origin, age groups, and race. The expected populations in 2000 are available with totals by sex, race, Hispanic origin, and age groups. Net migration estimates and net migration rates for each category also are included.

County-Specific Net Migration by Five-Year Age Groups, Hispanic Origin, Race and Sex: 2000-2010 (ICPSR 34638)

Released/updated on: 2013-09-05

Geographic coverage: United States

Time period: 2000-01-01--2010-01-01

These data include county-level, net migration estimates by five-year age cohorts and sex, and by race and Hispanic origin, for the intercensal period from 2000 to 2010. The estimates were prepared using a vital statistics version of the forward cohort residual method. These estimates (and the net migration rates derivable from them) extend the set of decennial estimates of net migration that have been produced following each decennial census beginning with 1960 (net migration for the 1950s: Bowles and Tarver, 1965; 1960s: Bowles, Beale and Lee, 1975; 1970s: White, Mueser and Tierney, 1987; 1980s: Fuguitt, Beale, and Voss 2010; and 1990s: Voss, McNiven, Hammer, Johnson and Fuguitt, 2004).

County-Specific Net Migration Estimates, 1980-1990 [United States] (ICPSR 26761)

Released/updated on: 2010-04-02

Geographic coverage: United States

Time period: 1980-01-01--1990-01-01

This data collection represents a set of United States county net migration estimates by age and sex for the 1980-1990 decade, and is part of a series of estimates done for each decade since 1950 (1950-1970: see NET MIGRATION OF THE POPULATION BY AGE, SEX, AND RACE, 1950-1970 [ICPSR 8493]; 1970-1980: see NET MIGRATION OF THE POPULATION OF THE UNITED STATES BY AGE, RACE, AND SEX, 1970-1980 [ICPSR 8697]; 1990-2000: see COUNTY-SPECIFIC NET MIGRATION BY FIVE-YEAR AGE GROUPS, HISPANIC ORIGIN, RACE, AND SEX, 1990-2000 [ICPSR 4171]).

Net migration, the difference between the number of people moving into an area and the number moving out over a period, is measured here, and in all the other sets of estimates in the series, by the residual method. That is, net migration is equal to the population change over the period minus the natural increase (births -- deaths). Full details on how natural increase is estimated for each county, as well as other details of the data collection, are described in the codebook.
