The data in this table are based on the American Community Survey and/or the Puerto Rico Community Survey conducted in 2006. To maintain confidentiality, the Census Bureau applies statistical procedures that introduce some uncertainty into data for geographic areas with small population groups. The data in this table contain sampling error and nonsampling 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.
