1 Synthetic interviews were part of an effort to improve American Community Survey estimates of the group quarters population for substate areas. Synthetic interviews were created by imputing the characteristics of interviewed group quarters persons into group quarters facilities that were not in sample that year or period. Final actual interviews are the interviews obtained from sampled group quarters residents. For more information, see the User Note on synthetic interviews.
