Data Location:

You can find the variables described in this document in the CSV files here.
CSV files are organized by year and spatial scale. For example, county-level variables from 2000 will be found in C_2000.csv.
Note: Every variable can be found in the Latest files.

Data Source(s) Description:

Variables were obtained from the 2014 - 2018 American Community Survey (ACS), tables B25002, B25024, B25003, and B25026, each at the State, County, Tract and ZIP Code Tabulation Area (ZCTA) levels. Raw data and more details can be found at https://data.census.gov.

Description of Data Source Tables:

B25002 : Occupancy status
B25024 : Units in structure
B25003 : Tenure
B25026 : Total population in occupied housing units by tenure by year householder moved into unit

Description of Data Processing:

The following variables were included from B25002:

  1. Estimate; Total Units
  2. Estimate; Occupied Units
  3. Estimate; Vacant Units

The following variables were included from B25024:

  1. Estimate; Mobile homes

The following variables were included from B25003:

  1. Estimate; Total Occupied Units
  2. Estimate; Owner Occupied Units
  3. Estimate; Renter Occupied Units

The following variables were included from B25026:

  1. Estimate; Total Population in owner occupied units
  2. Estimate; Total Population in owner occupied units moved in before 1989
  3. Estimate; Total Population in owner occupied units moved in between 1990 and 1999
  4. Estimate; Total Population in renter occupied units
  5. Estimate; Total Population in renter occupied units moved in before 1989
  6. Estimate; Total Population in renter occupied units moved in between 1990 and 1999

  • Occupancy rate was calculated as : Occupied units / Total units

  • Vacancy rate was calculated as : Vacant units / Total units

  • Rental rate was calculated as : Renter occupied units / Total occupied units

  • Percentange of mobile housing structures was calculated as : Mobile units / Total units

  • Long-term occupancy rate was calculated as : (Owner & renter populations moved in before 1989 + Owner & renter population moved in between 1990 & 1999) / (Total population in owner & renter occupied units)

  • Housing Unit Density was calculated as : Total Housing Units / Land area in square miles
    Note: Total land area for each spatial scale was sourced from geometry files and converted to square miles.
