Local Update of Census Addresses

Oklahoma and the U.S. Census Bureau are preparing for the 2020 decennial Census. For Oklahoma tribes, cities and towns to be properly represented, local government participation is needed in the Local Update of Census Addresses (LUCA) program.

LUCA is the only opportunity for Oklahoma’s local government officials to review and comment on the U.S. Census Bureau’s residential address list prior to the 2020 Census.

Why Participate

Nationally, $589.7 billion in annual federal assistance funding is tied to Census Bureau data. Oklahoma’s portion is $6.55 billion per year. An accurate population count is necessary for Oklahoma to receive its fair share of funds and to ensure your community receives proper funding. These programs include:

  • Medicaid
  • SNAP
  • Medicare Part B
  • Title 1 grants for education, highway planning and construction
  • Section 8 Housing
  • Head Start

A full population count will also help you plan for your community’s future needs.

If your community needs assistance from the Oklahoma Department of Commerce, contact Jon Chiappe at or 405-815-5210.
