2010 LUCA

Redistricting is the process by which states revise political boundaries within the United States.  To accomplish this task, the US Census Bureau has setup the 2010 Redistricting Program, which is partitioned into the following 5 phases:

Phase 1 - State Legislative District Project (2004-2006) completed

This phase involved the collection of State Legislative District (SLD) boundaries by the Census Bureau and was the first effort post-Census 2000 to update SLD boundaries. After SLD boundaries were collected, the Census Bureau prepared tabulations for legislative districts based on Census 2000 data.

Phase 2 - Voting District/Block Boundary Suggestion Project (2007-2009) completed

This phase is currently underway and involves the collection of voting district boundaries from county supervisors of election office.  These boundaries are geo-referenced and reviewed by the local county supervisors of elections offices and then submitted to the US Census Bureau by the Florida Legislature.  These submitted boundaries will be included in the delivery of the 2010 Census tabulations during phase 3 of this program.

Phase 3 - Data Delivery for the 2010 Census Redistricting Data Program (2010-2011) completed

This phase will include the delivery of the geographic products and data products to the official designated liaisons. Geographic products will precede the Public Law (PL) 94-171 data tabulations that are mandated by law for delivery no later than April 1, 2011, one year following Census Day.

Phase 4 - Collection of the Post-2010 Census Redistricting Plans  (2012-2013)

This phase will include the collection of State Legislative District and Congressional plans drawn using the Phase 3 materials. The Census Bureau will produce both geographic and data products required for delivery to the United States Postal Services / Department of Justice (USPS/DOJ). In addition, they will produce materials for Congress and Congressional District data summaries/maps during this time.

Phase 5 - Evaluation and Recommendation for 2020 (2012-2014)

This phase will consist of a historical review by the states of the successes and failures of the Census Bureau to meet the Public Law 94-171 requirements. The Bureau will produce a final report with the view of the states expressed for the program in Census 2020.

Local Update of Census Addresses (LUCA)

The Local Update of Census Addresses (LUCA) program was a decennial census geographic partnership program that allowed the Census Bureau to benefit from local knowledge in developing its Master Address File (MAF) for the 2010 Census. The program allowed local governments an opportunity to review and comment on the list of housing units and group quarters addresses that the Census Bureau used to deliver questionnaires within their community.

In order to ensure that all of Florida's housing units and group quarters were included in the 2010 Census, Florida established the Florida LUCA Program.  The Florida Legislature headed up this program and assisted the Census Bureau with promotional and training workshops, provided local governments with support, and awarded technical assistance grants.  The state was an integral partner in this program during the first phase of the program that occurred during 2007 and 2008.

The Census Bureau processed the submissions that they received from local governments and during the spring of 2009 they canvassed the state to validate the addresses on the updated Master Address File.  In the fall of 2009, local governments were given an opportunity to review what the Census Bureau found as a result of canvassing.  This was followed by an opportunity to challenge and appeal the results.
