The primary purpose of the 2010 Census Service-Based Enumeration Assessment Report is to describe how the Census Bureau conducted the 2010 Census Service-Based Enumeration Operation at service-based locations and targeted non-sheltered outdoor locations throughout the United States and Puerto Rico and to document the results of the operation. In addition, this report provides the number of service-based locations visited during the operation and demographic information about the people enumerated at those locations. Overall, the data from this report provide valuable information to be used for historical purposes as well as planning for future census enumeration operations at service-based locations and targeted non-sheltered outdoor locations.  

The 2010 Census Service-Based Enumeration Operation was implemented to provide people without conventional housing, including those experiencing homelessness, an opportunity to be included in the census by conducting the enumeration at service-based locations and targeted non-sheltered outdoor locations. Prior to conducting the enumeration operation at service-based locations, the Census Bureau conducted the 2010 Census Group Quarters Validation Operation and the 2010 Census Group Quarters Advance Visit Operation, both in preparation for the 2010 Census Service-Based Enumeration Operation.
