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)

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.

For more information about LUCA, please visit www.census.gov/programs-surveys/decennial-census/about/luca.html. (www.census.gov)

LUCA Technical Workshops

A schedule of LUCA Technical Workshops (www.census.gov) is now online. These workshops will provide 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. In addition to in-person workshops, several webinars have been scheduled. To register for a webinar, click on the link in the file. To register for an in-person workshop, e-mail los.angeles.geography@census.gov or call the main line at 818-267-1724. Specify the training location and date in the subject line and provide your jurisdiction and who will be attending.

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.

California LUCA Participation Incentive

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. 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 register to participate in the LUCA program with the U.S. Census Bureau. The deadline to register is December 15, 2017. If you cannot locate your forms, e-mail the Census Bureau immediately at geo.2020.luca@census.gov.
  2. To receive the incentive, local governments must participate in the LUCA Program and submit required materials to the Census Bureau. Materials will be sent out in the first quarter of 2018.
  3. Local governments must request incentive funds from the Department of Finance. Jurisdictions that have registered for LUCA with the Census Bureau will receive instructions on how to request incentive funds in early 2018.

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.
