Phase 1 of the 2020 Redistricting Data Program is the Block Boundary Suggestion Project (BBSP) being conducted in the first half of 2016. This program is your only chance to weigh in on the smallest Census geography that underpins all other Census geographies – the Census block. Are your block boundaries correct? Are they where you need them to be? Have a say in which boundaries are important to you and your jurisdiction(s) and which are not. California must streamline its blocks as the geography exploded between the 2000 and 2010 Census’ from 533,000 to 710,000 – more than a 33% increase. While this project is of high importance for Redistricting and electoral district purposes, don’t forget the substantial uses of small area data for other data tabulation needs such as for grant writing, neighborhood profiles, etc.

The BBSP is an important part of the geographic preparations for the 2020 Census. California has designed the BBSP to allow its counties the opportunity to provide input about the features that will be designated as boundaries for census tabulation blocks in the 2020 Census. The BBSP also allows counties to submit suggested block boundary changes that may be of use in the post-2020 Census redistricting process or for other data tabulation purposes. The Statewide Database at UC Berkeley is coordinating this program and will host 8 workshops throughout the state.
