Preparation is underway for the 2030 Census, a headcount of every U.S. resident that forms the framework for billions of dollars of federal funding. The Oklahoma House of Representatives is working with the U.S. Census Bureau as part of the Redistricting Data Program to assist in this effort.

One key component of this program is the Block Boundary Suggestion Program (BBSP), which gives states the opportunity to recommend changes to census block boundaries, the smallest geographic unit used for census data collection.

The BBSP offers states the chance to preview the census tabulation blocks that will be used for the 2030 Census and to make suggestions for new boundaries. The program is also an opportunity to correct problematic census tabulation blocks and to create new blocks that can be used for other purposes, such as tabulating non-political boundaries.

The state's congressional, judicial, legislative and local election districts are built using whole census blocks. Any block boundary not present in the P.L. 94-171 Redistricting Data, which will be released by the Census Bureau in early 2031, cannot be used for redistricting.

The Oklahoma House of Representatives invites organizations and political subdivisions with a vested interest in Oklahoma census geography to request census block changes by studying this map and submitting the form for each block boundary suggestion. Submissions will be compiled and submitted to the Census Bureau by the state's nonpartisan redistricting liaison. The Census Bureau evaluates and decides on the requested block boundary changes.
