Section § 21003
This law requires the Department of Corrections and Rehabilitation to provide detailed information about each state-incarcerated inmate in California to the Legislature and the Citizens Redistricting Commission every ten years, starting in 2030. This information, to be furnished after the Census Day but within 90 days, includes a unique identifier for the inmate (not their name), their last known residential address before incarceration, and demographic details like race and ethnicity, without revealing specific inmate data publicly.
The aim is to use this information for accurate legislative redistricting, treating inmates as residents of their last known address rather than the prison. Inmates whose last known residence is outside California or is unknown are considered to reside at an unknown location within the state for district population counts.
The law ensures privacy by barring the publication of specific ethnic, racial, or address data and requires adjustments in racial and ethnic data for areas with prisons to reflect the revised local populations more accurately.
(a)Copy CA Elections Code § 21003(a)
(1)Copy CA Elections Code § 21003(a)(1) In 2030 and in each year ending in the number zero thereafter, the Department of Corrections and Rehabilitation shall furnish to the Legislature and the Citizens Redistricting Commission, in the form of a single electronic file for each database maintained by the department, information regarding each inmate incarcerated in a state correctional facility on
the decennial Census Day. This information shall be furnished not sooner than the decennial Census Day and not later than 90 days after the decennial Census Day.
(2)CA Elections Code § 21003(a)(2) The information furnished by the Department of Corrections and Rehabilitation pursuant to paragraph (1) shall include the following for each inmate:
(A)CA Elections Code § 21003(a)(2)(A) A unique identifier, other than the inmate’s name or Department of Corrections and Rehabilitation number.
(B)CA Elections Code § 21003(a)(2)(B) Any information maintained by the Department of Corrections and Rehabilitation about the residential address or addresses at which the inmate was domiciled before the inmate’s most current term of incarceration, including any available information about the date on which each address
was added to records maintained by the department. If the Department of
Corrections and Rehabilitation does not have any residential address information for an inmate, the information furnished by the department shall state that fact.
(C)CA Elections Code § 21003(a)(2)(C) The inmate’s ethnicity, as identified by the inmate, and the inmate’s race, to the extent such information is maintained by the Department of Corrections and Rehabilitation.
(D)CA Elections Code § 21003(a)(2)(D) The address of the state correctional facility where the inmate is incarcerated on the decennial Census Day.
(3)CA Elections Code § 21003(a)(3) The Department of Corrections and Rehabilitation shall exclude all inmates in federal custody in a facility within California from the information furnished pursuant to this section.
(b)CA Elections Code § 21003(b) In
order to comply with its obligation to ensure that a complete and accurate computerized database is available for redistricting in accordance with subdivision (b) of Section 8253 of the Government Code, the Legislature, in coordination with the Citizens Redistricting Commission, shall ensure that the information provided by the Department of Corrections and Rehabilitation pursuant to subdivision (a) is included in that computerized database.
(c)CA Elections Code § 21003(c) Notwithstanding subdivision (b), and regardless of the form in which the information is furnished by the Department of Corrections and Rehabilitation, the Legislature or the Citizens Redistricting Commission shall not publish information regarding the race, ethnicity, or prior residential addresses of specific inmates.
(d)CA Elections Code § 21003(d) Consistent with
Section 2025, the Citizens Redistricting Commission shall deem each incarcerated person as residing at that person’s last known place of residence, rather than at the institution of that person’s incarceration, and shall use the information furnished to it pursuant to subdivision (a) in carrying out its redistricting responsibilities under Article XXI of the California Constitution. The Citizens Redistricting Commission shall also do all of the following when it uses information regarding inmates that is furnished pursuant to this section:
(1)CA Elections Code § 21003(d)(1) Deem an inmate incarcerated in a state correctional facility for whom the last known place of residence is either outside California or cannot be determined, or an inmate in federal custody in a facility within California, to reside at an unknown geographical location in the state and
exclude the inmate from the population count for any district, ward, or precinct.
(2)CA Elections Code § 21003(d)(2) Adjust race and ethnicity data in districts, wards, and precincts that contain prisons in a manner that reflects reductions in the local population as inmates are included in the population count of the district, ward, or precinct of their last known place of residence and, to the extent practicable, those deemed to reside at an unknown geographic location.
(e)Copy CA Elections Code § 21003(e)
(1)Copy CA Elections Code § 21003(e)(1) For purposes of this section, “last known place of residence” means the most recent residential address of an inmate before the inmate’s most current term of incarceration that is
sufficiently specific to be assigned to a census block, as determined from information furnished by the Department of Corrections and Rehabilitation in accordance with this section. In the case of an inmate for whom residential address information is available but is not sufficiently specific to allow the address to be assigned to a census block, the “last known place of residence” means a randomly determined census block located within the smallest geographical area that can be identified based on the residential address information furnished by the Department of Corrections and Rehabilitation.
(2)CA Elections Code § 21003(e)(2) For purposes of this section, “state correctional facility” means a facility under the control of the Department of Corrections and Rehabilitation.
