What this measure is
The average number of people living in each occupied home. People in group quarters such as dormitories, prisons and nursing homes are not in households. It is a Census Bureau survey estimate pooled over five years; in census tracts and block groups, white stripes over the colour mark low reliability: a wide margin of error.
