... . PEP CONTROLS AND ALTERNATIVES To estimate subcounty GQ populations, the Census Bureau starts with GQ population counts by facility type for each subcounty area from the previous decennial census and updates them with a time series of individual GQ records from the group quarters report (GQR)

From page 23...
... Despite uncertainty surrounding the quality of the GQ estimates prepared by the PEP, the proposed evaluation research, as planned, will focus only on estimated population (household and GQ populations combined) , and household population compared with total 2010 census counts.

From page 24...
... ESTIMATES OF THE GQ POPULATION IN SMALL AREAS The decennial census, because of its role of providing complete counts of the population down to the census block level, mostly succeeds in completely enumerating the GQ population everywhere and is able to support counts by GQ type for all entities in the census geographic hierarchy. In contrast, the state-based sample design of the ACS is not an efficient vehicle for providing small-area estimates of the GQ population.

From page 25...
... Sources of GQ data that could be used in the model include, but are likely not to be limited to, counts of residents and group quarters for small areas as shown on the frame, the previous census counts of GQ population by small area, data provided by state or local agencies regarding GQ populations, or possibly the PEP subcounty estimates of the GQ population. Another option would be to investigate the use of administrative records maintained by GQ facilities for this purpose, even if these records are found not to be comprehensive enough to replace interviews with residents.

... Recommendation 4-6: In addition to continuing to publish margins of error to accompany the estimates, the Census Bureau should also develop a system for flagging estimates that are adversely affected by the presence of group quarters in the area. This procedure should continue until alternative methodologies are developed to reduce the variance in GQ estimates.
