Abstract

Early in 2003, the National Center for Health Statistics (NCHS) released population files for 2000 and 2001, based on the Census Modified Race Summary File, where multiple race counts on the Census file were distributed amongst the single-race counts. The objective of this talk is to describe the initial models used to distribute the multiple race counts, discuss issues associated with the original models, and present preliminary findings from ongoing work that may be used for future population counts. The National Health Interview Survey (NHIS) has allowed multiple race responses for many years and asks multiple race respondents to identify one of their responses as a primary race. Using the multiple-race responses in the NHIS, the primary race responses were used as the outcome variable in categorical regression models; individual- and county-level variables were included as covariates. Models and predictions differed markedly between multiple-race groups. Revisions to these models will include additional years of NHIS and new county-level variables from the 2000 Census.
