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 Vera Institute of Justice. Raw data and more details can be found at https://github.com/vera-institute/incarceration_trends. Raw data is downloaded in the folder of data_raw, named as "incarceration_trends.xlsx".

Description of Data Processing:

The following variables were included from the source data:

  1. Total prison population rate;
  2. Total prison admission rate;
  3. Total prison population count;
  4. Total prison admission count;

These rates were calculated using base rate of county population aged 15-64. They argue that "youth under age 15 and adults over 64 are age groups at very low risk of jail incarceration and because the proportion of these groups varies greatly by county."

  • Variable -- title of variable
