CDC WONDER: Population - Bridged-Race July 1st Estimates

<p>The Population - Bridged-Race July 1st Estimates online databases report bridged-race population estimates of the July 1st resident population of the United States, based on Census 2000 counts, for use in calculating vital rates. These estimates result from "bridging" the 31 race categories used in Census 2000, as specified in the 1997 Office of Management and Budget (OMB) standards for the collection of data on race and ethnicity, to the four race categories specified under the 1977 standards (Asian or Pacific Islander, Black or African American, American Indian or Alaska Native, White). Many data systems, such as vital statistics, are continuing to use the 1977 OMB standards during the transition to full implementation of the 1997 OMB standards. Postcensal estimates are available for year 2000 - 2009; intercensal estimates are available for the years 1990-1999. Obtain population counts by Year, State, County, Race (4-categories), Ethnicity, Sex and Age (1-year or 5-year groups). The data are released by the National Center for Health Statistics.</p>

《人口统计 - 跨种族7月1日估算》在线数据库报告了基于2000年人口普查计数，针对美国7月1日居住人口的跨种族人口估算，以供计算生命率之用。这些估算结果源于将2000年人口普查中使用的31个种族类别，根据1997年管理预算办公室（OMB）关于种族和民族数据收集的标准进行“桥接”，至1977年标准下规定的四个种族类别（亚洲或太平洋岛民、黑人或非裔美国人、美洲印第安人或阿拉斯加原住民、白人）。众多数据系统，如生命统计，在过渡至完全实施1997年OMB标准期间，仍在继续使用1977年OMB标准。2000年至2009年的后人口普查估算数据可用；1990年至1999年的跨人口普查估算数据也可用。可按年份、州、县、种族（四类别）、民族、性别和年龄（一年或五年组）获取人口计数。数据由国家健康统计中心发布。
