To maintain confidentiality, the Census Bureau applies statistical procedures that introduce some uncertainty into data for small geographic areas with small population groups. The census results in this table contain nonsampling error, but do not contain sampling error. Data users who create their own estimates using data from American FactFinder tables should cite the Census Bureau as the source of the original data only. See also definitions of subject characteristics and geographic definitions. The data in this table have not been adjusted for estimated net census coverage error based on the results of the Accuracy and Coverage Evaluation.
Census count corrections (PDF 45KB) for American Indian and Alaska Native Areas (AIANAs), states, counties, places, county subdivisions, census tracts, and blocks may have been released as a result of an external challenge through the Count Question Resolution Program.
