For the release of the 2011 ACS 1-year estimates, the Census Bureau produced reports for the American Community Survey Briefs series -- short reports on specific topics based on the newly released estimates.
Increased representation of group quarter estimates for sub-state geographies
Due to revised methodology, there is increased representation of major group quarter (GQ) types for sub-state geographies compared to previous years. The GQ sample data has been supplemented with additional information from a new imputation procedure. For more information, read the ACS Group Quarters Small Area Estimation user note.
