NEWTON, MASSACHUSETTS (USA) – Household size distributions
are critical inputs to many business analyses but may not be
correctly derived from U.S. Census data. The Census counts people at
their geographic locations, and when several unrelated people live
at the same address they are reported as one household with a number
of residents. A confusing array of data is reported. In both the
Census SF1 2010 file and in 2017 ACS, the following tabulations are
provided down to the Census tract level:
-
People in Family Households
-
2 person Family Households
-
3 person Family Households
-
4 person Family Households
-
5 person Family Households
-
6 person Family Households
-
7+ person Family Households
-
Non-relatives in Family Households
- Unmarried Partners (including same-sex couples) in Family Households
-
People in Non-Family Households
- Unmarried Partners (including same-sex couples) in Non-Family Households
There is also extensive information on people residing in group
quarters in the 2010 Census, which has the tabulations below:
- People in Group Quarters: College
- People in Group Quarters: Military
- People in Group Quarters: Navy Ships
- People in Group Quarters: Other
- People in Group Quarters: Homeless
- People in Group Quarters: Group Homes
- People in Group Quarters: Residential Treatment
- People in Group Quarters: Merchant Ships
- People in Group Quarters: Workers’ Group Living Quarters
- People in Group Quarters: Other Other
- People in Group Quarters: Institutionalized
Using this information, Maptitude 2019 includes a corrected data set
of household size distributions for Census Tracts and Block Groups
to account for the under-representation of one-person households in
the Census data.
