Population and Housing Profile: Washington city, District of Columbia pt.,District of Columbia

NOTES: The population estimates in this profile are limited to the household population and exclude the population living in institutions, college dormitories, and other group quarters.  

In the narrative profile below, if one sample estimate is larger than another, it does not necessarily mean that the same holds for their true values for the entire population. These estimates are derived from a sample of housing units and measure the true values with a degree of uncertainty. In the tabular profiles this uncertainty is represented by the 90 percent confidence interval given for each estimate. For further information on confidence intervals see the Accuracy of the Data document.

Caution should be used when comparing data by race for years before 1999 with those for 2000 due to the Census Bureau's implementation of the October 1997 revised standards for data on race and ethnicity. For the 2000 data, respondents may report one or more races and there are seven (American Indian and Alaska Native, Asian, Black or African American, Native Hawaiian and Other Pacific Islander, White, Some other race, and Two or more races) instead of five racial tabulation categories. The Two or more races category includes all respondents who reported more than one race. See the methodology section for more details regarding these changes.

In addition, caution should be used when comparing population numbers by age, race, and sex for 2000 with all earlier years. The numbers for 2000 have been weighted to be generally consistent with Census 2000 counts.

Detail may not add to totals due to rounding. Percentages are based on unrounded numbers
