2020 Census

The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions in federal funds to local communities.

Local Update of Census Addresses (LUCA)

General Information - Flyer and Guide.

An accurate population count starts with an up-to-date and complete address list. The LUCA program provides state, local and tribal governments with a once-in-a-decade opportunity to update the Census Bureau’s address list that is used to conduct the decennial census. State, local and tribal government participation in the 2020 LUCA program can contribute to a more accurate population count for their communities.

California LUCA Participation Incentive Fund

In recognition of the importance of LUCA, the State of California has established an incentive fund to encourage cities and counties to participate in the program and to help mitigate some of the cost of that participation. See the Frequently Asked Questions for more information.

The amount of the incentive each jurisdiction receives is based on the housing activity (building, demolitions and annexations) from April 1, 2010, to January 1, 2017, using estimates from the Demographic Research Unit. Additional funds may be added for jurisdictions which experienced a disaster area declaration since 2010. A minimum of $7,500 will be available for each jurisdiction that applies for the incentive and participates in the program. The award amounts may increase subject to the overall level of LUCA participation. See the List of LUCA Incentive Awards for the specific minimum award for your jurisdiction.

The California Department of Finance will administer the LUCA incentive fund. There are three requirements to receive an award:

  1. Local governments must have registered to participate in the LUCA program with the U.S. Census Bureau. The registration period is now closed.
  2. To receive the incentive, local governments must participate in the LUCA Program and submit required materials to the Census Bureau. Materials were sent to most jurisdictions in California in March 2018.
  3. Local governments must request incentive funds from the Department of Finance within 30 days of returning their LUCA materials to the Census Bureau. The LUCA liaison for jurisdictions that have registered for LUCA with the Census Bureau will receive instructions in late March 2018 via e-mail on how to request incentive funds. For more information on requesting your award, e-mail ficalpop@dof.ca.gov .

Registration is Closed

In order to participate in LUCA, a city, county, or tribal council MUST have registered by December 15, 2017. To see if your jurisdiction is registered to participate in LUCA go to Census Bureau map of registered jurisdictions (www.census.gov)

LUCA Technical Workshops

These workshops provided detailed information on what materials will be provided, how the participants will review the Census Bureau address listings, and how to report changes, such as missing or duplicated addresses, to the Census Bureau. The Census Bureau has posted slides and notes from its LUCA training presentation (updated December 2017). The 2020 Census LUCA Training Presentation (www.census.gov) and the accompanying 2020 LUCA Training Presentation Script (www.census.gov) provide basic information about LUCA, the importance of participating in LUCA, and how to participate in LUCA.

LUCA Informational Workshops

LUCA workshops were held in mid-2017 to provide an overview of the program, explain how it will benefit your community, and provide an opportunity to ask questions. The workshops also covered program goals, participation methods, and security guidelines.
