This report documents the National Center for Health Statistics' (NCHS) methods for bridging the Census 2000 multiple-race resident population to single-race categories and describing bridged race resident population estimates. Data came from the pooled 1997-2000 National Health Interview Surveys. The bridging models included demographic and contextual covariates at the person or county level. Allocation probabilities from the regression models were applied to the Census Bureau's 2000 Modified Race Data Summary File population counts to assign multiple-race persons to single-race categories. Bridging has the most impact on American Indian and Alaska Native (AIAN) and Asian or Pacific Islander (API) populations, a small impact on the black population, and a negligible impact on the white population. For the country overall, the AIAN, API black, and white bridged population counts are 12.0, 5.0, 2.5, and 0.5 percent higher than the corresponding Census 2000 single-race counts. There is considerably more variation at the subnational than the national level. Bridged single-race population counts have been used to calculate birth and death rates produced by NCHS for 2000 and 2001 and to revise previously published rates for the 1990s, 2000, and 2001. The bridging methodology will be used to bridge postcensal population estimates for later years. Bridged population counts presented here and in subsequent years may be updated as additional data become available for use in the bridging process. File layouts are appended. (SM)
