The Group Quarters Facilities data layer contains information on both institutional and non-institutional group quarters facilities in Southeast Michigan. According to the Census Bureau, group quarters are places where people live or stay, in a group living arrangement, that is owned or managed by an entity providing housing and/or services for the residents. This is not a typical household-type living arrangement and the people living in group quarters are usually not related to one another. It is important to monitor the group quarters population because they are sampled as individuals within Census Bureau surveys, rather than as members of a household unit, and less information is reported.

Group Quarters Types

Institutional group quarters provide supervised custody or care to inmates or residents. This includes correctional facilities, assisted living, nursing homes, and memory care.

Non-institutional group quarters house residents who are able or eligible to be in the labor force. This includes student and military housing, group homes, residential treatment centers, and religious housing.

Group Quarters Facility Counts

Data on group quarters facilities is decentralized, and collected from a variety of federal and state agencies, educational institutions, industry associations, and private sources.

Group Quarters Facility Attributes

SEMCOG maintains a limited number of attributes on the group quarters facility points data layer. Please note that because a single building may contain group quarters of different types, there will be cases where there is multiple records for a single structure. Table GQ.1 list the current attributes of the buildings dataset:

Group Quarters Classification Code

SEMCOG’s group quarters classification codes are adopted from the coding system established by the U.S. Census Bureau to classify group quarters in their data products. There are several Census codes not used by SEMCOG as our region does not contain those types of facilities, and one additional code added for a different type of facility. More information on Census group quarters codes, including full descriptions of each classification, can be found on the Census Bureau’s web site.

SEMCOG classifies student housing differently than the Census, separating dorms from fraternities and sororities regardless of whether they are located on campus. In addition, student cooperative housing is added as an additional type due to the large number of such buildings in Ann Arbor.

In addition, Census counts of homeless persons are distributed to government buildings in the largest community in each county and the City of Detroit to ensure their inclusion in the data layer.
