Introduction

Data on the population currently incarcerated under the California Department of Corrections and Rehabilitation (CDCR) as of December 2023 and April 2025. Information was acquired via the California Public Records Act (CPRA). The Department applied several privacy (health information, age, etc.) related exclusionary criteria to release these records to Redo.io. The CDCR identification numbers are anonymized for an additional layer of privacy and security.

Demographics

Files: demographics.csvdemographics.xlsx

Variable	Type	Calculated	Description
cdcno	str	No	Unique identifier (MD5 hash) for each individual under CDCR jurisdiction, including those housed in a state prison, temporarily released, or held in a non-CDCR facility. Excludes parolees. Individuals serving CDCR sentences in county jails are included.
ethnicity	str	No	Race or ethnicity of the incarcerated person (e.g., White, Black, Asian, Hispanic, Pacific Islander).
current age	int	No	Age in whole years as reported by CDCR, current as of the date the data was reported. Note: This is a snapshot value, not a fixed attribute.
controlling offense	str	No	California penal, vehicular, or other code number for the offense governing the individual's current incarceration (e.g., PC187, PC664, PC214(a)).
description	str	No	Text description of the controlling offense.
offense begin date	datetime	No	Date the controlling offense began.
offense end date	datetime	No	Date the controlling offense ended, if applicable.
controlling case number	str	No	Case number associated with the controlling offense.
controlling case sentencing county	str	No	County where the individual was sentenced for the controlling offense.
sentence type	str	No	Indicates whether the individual is sentenced to a Determinate Sentence Length (DSL), Life with Parole, Life Without Parole (LWOP), Third Strike, Second Strike, or Condemned.
aggregate sentence in months	int	No	Total sentence length in months. Note: "Condemned" sentences are recorded as 100,000 or 1,000,000 months.
offense category	str	No	Broad category of the offense (e.g., drug crimes, property crimes, crimes against a person).
eprd mepd month and year	str	No	For determinate sentences: Earliest Possible Release Date (EPRD), calculated from the court-imposed sentence minus applicable credits. For indeterminate sentences: Minimum Eligible Parole Date (MEPD), the earliest date a "lifer" may be considered for parole.
current location	str	No	Name of the facility where the individual is currently housed. Note: CDCR sentences being served in county jails typically appear as " Control Office".
aggregate sentence in years	float	Yes: aggregate sentence in months divided by 12	Total sentence length in years.
time served	float	Yes: today's date minus offense end date	Total sentence length in years that has been completed. Note: This value represents the minimum time served. Because the value is refreshed every 3-4 months, the actual time served at any given point may be greater than what is recorded.
expected release date	datetime	Yes: offense end date + aggregate sentence in years	Possible release date based on sentence length and offense date.
estimated age at offense	int	Yes: current age minus (date of data release minus offense begin date)	Estimated age in years on the offense begin date. Note: This value carries some uncertainty, because CDCR reports age as a whole number and does not release date of birth. For example, a person recorded as 45 years old may have turned 45 at any point during the past year, so their age at a 2015 offense could have been 34 or 35.
probable juvenile at offense	str	Yes: estimated age at offense less than 19	Whether the individual was likely under 19 years old at the time of offense. Note: This reflects an estimate, not a legal determination, and carries the same uncertainty as the age it is based on. For example, a person estimated at 18 at the time of offense may actually have been 17 or 19, so records close to the cutoff may fall on either side. The threshold used here is under 19, which is not the statutory juvenile cutoff in California of under 18.
