LEGISLATIVE COUNSEL'S DIGEST

AB 1878, as amended, Patel. ~~Demographic data: collection: report.~~ Data collection: race and ethnicity.

Existing law requires state agencies, boards, or commissions that directly or by contract collect demographic data on the ethnic origin, ethnicity, or race of Californians to use specified collection categories for Middle Eastern, North African, Asian, Native Hawaiian, Pacific Islander, Black, and African American groups.
Existing law establishes within the Government Operations Agency the Office of Data and Innovation, whose mission is to deliver better government services to the people of California through technology and service innovation, data, and design. Existing law requires the Governor to appoint a Chief Data Officer in the Office of Data and Innovation.
This bill, subject to a specified exception, would require any state agency, board, or commission that directly or by contract collects demographic data on the ethnic origin, ethnicity, or race of Californians to collect and publish data on detailed race and ethnicity categories, as provided. The bill would require compliance with these provisions by January 1, 2029. The bill would prohibit these provisions from being construed to affect certain provisions regarding the collection of demographic data as to the ancestry or ethnic origin of California residents. The bill would also prohibit its provisions from being construed to prevent a state agency from tabulating and reporting demographic data in accordance with state or federal requirements and standards.
This bill would require the Office of Data and Innovation to, among other things, standardize the collection of demographic data across state agencies, as provided. The bill would require the Chief Data Officer and the Office of Data and Innovation to oversee implementation of these provisions and provide technical assistance.
This bill would require, on or before January 1, 2028, and annually thereafter, each state agency, board, or commission required to comply with the bill’s provisions to submit a report to the Legislature and the Assembly Committee on Governmental Organization on compliance with these provisions, as provided. The bill would require data collected pursuant to this section to be made available to the public in accordance with state and federal law, except for personal identifying information, as specified. The bill would prohibit an agency from disclosing personal identifying information to any federal agency unless the disclosure is expressly required by federal law. The bill would require an agency to adhere to best practices in government data and to apply data equity practices, as provided.
Existing constitutional provisions require that a statute that limits the right of access to the meetings of public bodies or the writings of public officials and agencies be adopted with findings demonstrating the interest protected by the limitation and the need for protecting that interest.
This bill would make legislative findings to that effect.
Existing law requires any state agency, board, or commission that directly or by contract collects demographic data on the ethnic origin, ethnicity, or race of Californians to take certain actions, including providing forms that offer respondents the option of selecting one or more ethnic or racial designations.
This bill would require those state agencies, boards, or commissions to, by January 1, 2028, report to the Legislature on its implementation of and compliance with those requirements. The bill would repeal this reporting requirement on January 1, 2032.

SEC. 4.
The Legislature finds and declares that Section 2 of this act, which adds Section 8310.9.5 to the Government Code, imposes a limitation on the public’s right of access to the meetings of public bodies or the writings of public officials and agencies within the meaning of Section 3 of Article I of the California Constitution. Pursuant to that constitutional provision, the Legislature makes the following findings to demonstrate the interest protected by this limitation and the need for protecting that interest:
In order to protect the privacy of California residents, while also gathering and publicizing useful demographic data, it is necessary that personal identifying information remain confidential.

SECTION 1.Section 8310.9 of the Government Code is amended to read:
8310.9.
~~(a)The Legislature hereby finds and declares all of the following:~~
(1)The State of California currently has the largest population of people in the United States who identify with more than one ethnicity or race. This population of Californians who identify as multiracial is rapidly growing.
(2)Many state forms that currently require respondents to choose only a single ethnicity or race force multiracial Californians to deny a significant part of their heritage. Information collected in this manner often deprives the state of accurate data with which to meet the needs of its diverse communities.
~~(3)It is in the best interest of the State of California to respect, embrace, and understand the full diversity of its citizens.~~
(4)Since 1997, the federal Office of Management and Budget’s “Standards for Maintaining, Collecting, and Presenting Federal Data on Race and Ethnicity” have required federal agencies to ensure that individuals have the option of selecting one or more ethnic or racial designations on federal government forms requesting this information.
~~(b)Any state agency, board, or commission that directly or by contract collects demographic data on the ethnic origin, ethnicity, or race of Californians shall do all of the following:~~
(1)Provide forms that offer respondents the option of selecting one or more ethnic or racial designations. Recommended forms for the instruction accompanying a multiple response question are “mark one or more” or “select one or more.”
(2)Ensure in cases when data on respondents’ ethnic origin, ethnicity, or race is reported to any other state agency, board, or commission that it is neither tabulated nor reported without all of the following:
~~(A)The number or percentage of respondents who identify with each ethnic or racial designation alone and not in combination with any other ethnic or racial designation.~~
~~(B)The number or percentage of respondents who identify with each ethnic or racial designation, whether alone or in combination with other ethnic or racial designations.~~
~~(C)The number or percentage of respondents who identify with multiple ethnic or racial designations.~~
(D)For civil rights monitoring and enforcement, complying with the rules for multiple race response allocation issued by the federal Office of Management and Budget Bulletin No. 00-02 in cases of state or federally mandated actions related to an ethnic or a racial community, or to assessing disparate impact or discriminatory patterns. In these cases, the requirement of subparagraph (C) shall not be considered satisfied without also complying with the requirements of subparagraphs (A), (B), and (D).
(c)Each state agency, board, or commission required to comply with subdivision (b) shall comply as early as reasonably feasible when updating forms, software, hardware, or information collection procedures, and in no event later than January 1, 2022.
(d)Notwithstanding any other provision of this section, any state agency, board, or commission that collects demographic data from a local agency may continue to collect and report that data to any other state agency, board, or commission in the form that the local agency submits it.
(e)Notwithstanding any other provision of this section, any state agency, board, or commission that collects ethnic or racial data solely to comply with federal requirements may continue to collect and report that data to any other state agency, board, or commission in the form required by the federal government.
(f)(1)By January 1, 2028, each state agency, board, or commission subject to this section shall report to the Legislature, in compliance with Section 9795, on its implementation of and compliance with the requirements of subdivision (b).
~~(2)Pursuant to Section 10231.5, this subdivision is repealed on January 1, 2032.~~
