Corrected 2010 Census Total Population, Household Population, Group Quarters Population, Total Housing Unit, Occupied Housing Unit, and Vacant Housing Unit Counts. ERRATA: The U.S. Census Bureau publishes corrections to the 2010 Decennial Census data which are the result of the 2010 Census Count Question Resolution (CQR) Program. Please note that the errata are published in PDF form and are not included in the online downloads from the Census Bureau's American FactFinder website. In addition, because only the six variables listed above are corrected in the errata, other variables, such as age, sex, and race/ethnicity, are not corrected and totals amongst the variables (errata vs. non) may differ. For ease of reference, the CDR has packaged this corrected data below.
