LUCA is the only opportunity offered to tribal, state, and local governments to review and comment on the U.S. Census Bureau's residential address list for their jurisdiction prior to the 2020 Census. The Census Bureau relies on a complete and accurate address list to reach every living quarters and associated population for inclusion in the census. The Census Address List Improvement Act of 1994 (Public Law 103-430) authorizes the LUCA.

LUCA Closeout is under way for participants who did not file an appeal with the LUCA Appeals Office. To close out your government’s participation in LUCA, please fill out and sign the D-2012, Destruction or Return of Title 13 Materials Form, and return it to the Census Bureau by mail or email. Governments who filed appeals should wait to destroy or return their materials and send a D-2012 form after they receive a determination letter from the LUCA Appeals Office. See the “What are the LUCA Closeout Phase Materials?” section below for more information.

Who Can Participate?

Active, functioning governments were eligible to participate in LUCA for areas including:

  • Federally recognized tribes with a reservation or off-reservation trust lands;
  • States;
  • Counties;
  • Cities (incorporated place); and
  • Townships (minor civil divisions).

If governments lacked the resources to participate in LUCA, they were able to arrange for a higher level of government, such as county, or an organization, such as regional planning agency or council of governments, to conduct their review.

To see which governments sent LUCA responses, view the LUCA Respondent Viewer map.

  • An accurate count helps the federal government annually allocate more than $675 billion across 26 federal agencies for tribal, state, and local government programs and services.
  • To help communities plan for future needs.

What are the LUCA Closeout Phase Materials?

After the conclusion of the LUCA Feedback Phase, including receiving a final determination from the LUCA Appeals Office for those governments who choose to file an appeal, LUCA participants must destroy (preferred method) or return to the Census Bureau all of their Title 13 protected materials. 

LUCA Liaisons must certify the destruction (preferred method) or return of all Title 13 materials on the D-2012, which they must complete, sign, and return to the Census Bureau. If people who signed the D-2005, Confidentiality Agreement Form, are no longer available to sign out on a D-2012 form, the LUCA Liaison may sign out on their behalf in Section A of the form. If the LUCA Liaison is no longer available, the Highest Elected Official (HEO) may sign Section A of the D-2012 form to certify that their government no longer has any Title 13 protected materials.

To return a completed D-2012 form to the Census Bureau, mail the form to the Census Bureau using the prepaid envelope included in the Feedback or Review Phase packages, or in another envelope using this address:

ATTN LUCA BLDG 63E
National Processing Center
1201 E. 10th Street
Jeffersonville, IN 47123
