To help identify some of the correctional facilities counted by the census above, you may find it helpful to use this list of state, federal and local correctional facilities, their addresses, and their recent populations in: California.

Additionally, there are some facilities that the Census Bureau appears to have either missed or counted as something other than an adult correctional facility in their 2020 count. We track these omissions in an external list — currently this file lists errors found in the following states: California, Colorado, Delaware, Florida, Illinois, Louisiana, Massachusetts, Michigan, Montana, Nevada, New Jersey, New York, North Carolina, Pennsylvania, Virginia, Washington, Wisconsin.

Explanation of data elements

State
The state that the census block is in.
County
States are divided in to counties or county-equivalents.
Tract
Census tracts are small, relatively permanent statistical subdivisions of a county, delineated by local committees of census data users for the purpose of presenting data. Census tract boundaries normally follow visible features, but may follow governmental unit boundaries and other non-visible features. Designed to be relatively homogeneous in population characteristics, economic status, and living conditions at the time of establishment, census tracts average about 4,000 inhabitants. Each tract in a county has an identifying number.
Block
Blocks are the smallest units of Census geography and are assigned numbers.
Correctional Population
This is the number of people reported as being incarcerated in this Census block.
Facility Name
If we have manually identified the correctional facility or facilities in this Census block, we've labeled it here.
Facility Type
If we have manually identified the correctional facility by type, we have labeled it here. We have found that the Census Bureau's labels, provided in Summary File 1, Table PCT16, are so error-prone as to be unreliable. If your analysis requires you to remove local facilities and halfway houses, you will need to identify the facilities manually.
Wrong Block
If we know that the Census Bureau placed a facility in the wrong location, we have noted it here.
Comment
Any other notes from our manual research are reported here.
Map
This link shows a Google map of the location, including the satellite view. The marker reflects the center point of the block, but the prison itself may be some distance from this center point.
