The 2010 Census Enumeration at Transitory Locations assessment documents the results of the following:

• Enumeration at Transitory Locations
• Enumeration at Transitory Locations Reinterview

The Enumeration at Transitory Locations operation enumerated people at transitory locations who did not have a usual home elsewhere. Transitory locations are recreational vehicle parks, campgrounds, hotels, motels (including those on military sites), marinas, racetracks, circuses, and carnivals.

The Enumeration at Transitory Locations Reinterview was a quality control check on the enumerators’ work. Reinterview had two components, one for the transitory location and the other for the housing unit, or questionnaires received for that housing unit.

The 2010 Census was the first time the Enumeration at Transitory Locations operation was conducted separate from Group Quarters enumeration. Enumeration at transitory locations is different from enumeration at Group Quarters, supporting the need for a separate enumeration operation. Group Quarters enumerators were instructed to interview all people at Group Quarters locations; however, at transitory locations, enumerators were instructed to conduct an interview with only people who had no usual home elsewhere. In addition, the operations used separate questionnaires. The 2010 Census Group Quarters Enumeration operation used an Individual and Military Census Return, and Enumeration at Transitory Locations used the Transitory Location Enumerator Questionnaire to conduct interviews.
