Bridged-race intercensal population estimates for July 1, 1990-July 1, 1999, by year, county, single-year of age, Hispanic origin, and sex

These estimates represent a revision of the annual time series of July 1 county population estimates by age, sex, race, and Hispanic origin that were based on the 1990 census. These estimates incorporate the bridged single-race estimates of the April 1, 2000, resident population (see above). The bridged-race intercensal population estimates were produced by the Population Estimates Program of the U.S. Census Bureau with support from the National Cancer Institute.

The county, State, and national single-year of age intercensal files below replace the county-level single-year of age intercensal files previously released on April 30, 2004. The previously released files have been replaced because they contained some -1 population counts (see file documentation for explanation).

Bridged-race intercensal population estimates for July 1, 1990-July 1, 1999, by year, county, 5-year age groups, bridged-race, Hispanic origin, and sex

The bridged-race intercensal estimates for 1990-99 on this Web site differ from the estimates released on the NCI Web site. NCI modified the Census Bureau’s estimates for the State of Hawaii. The Epidemiology Program of the Hawaii Cancer Research Center has developed their own set of population estimates, based on sample survey data collected by the Hawaii Department of Health. This effort grew out of a concern that the native Hawaiian population has been vastly undercounted in previous censuses. The NCI adjustment to the Census Bureau Hawaii estimates has the net result of reducing the estimated White population and increasing the Asian and Pacific Islander population for the State. NCI did not modify the Census Bureau estimates for Hawaii’s total population, Black population, or American Indian and Alaska Native population.
