2020 Census: Information for State and Local Governments

Background

2020_cenusEvery ten years the U.S. Census Bureau conducts a census of the population of the United States. The Decennial Census began in 1790 and each census involves years of planning to ensure a successful and complete count. With the 2020 Census approaching the U.S. Census Bureau is actively engaged in the planning for the 2020 Census and this planning process includes the need for input and information from state and local governments. This page includes details on the 2020 Census planning activities, training, and resources for state and local governments.

 

 

2020 Census Boundaries

Every 10 years, the boundaries definitions are reviewed and updated and this presents an opportunity for local, state governments, and the public to provide input and assist in the defining of the boundaries and related details. The geographies of the U.S. Census are defined below and the boundaries where local, state government, and public input is valuable is the defining of Census Tracts, Block Groups, and Blocks.

The Boundary and Annexation Survey (BAS)

Boundary and Annexation Survey (BAS)

The U.S Census Bureau conducts the Boundary and Annexation Survey (BAS) annually in order to collect informaiton about selected legally defined geographic areas. The purpose of the BAS is to update information about legal boundary and names of all government units in the United States.

Each year in Connecticut, state, federally recognized American Indian tribes, and municipal officials receive a request from the U.S. Census Bureau to verify if there are any changes in the legally defined boundaries. The Connecticut State Data Center assists the U.S. Census Bureau with non-response follow-ups to ensure any changes are reported as well as to confirm that no changes occurred to legal boundaries.

The annual schedule for the BAS is as follows:
January - Materials are mailed to each state, federally recognized American Indian tribes, and municipal officials by the U.S. Census Bureau
March 1 - Deadline for submitting updates to the U.S. Census Bureau
March - May - Connecticut State Data Center assists U.S. Census Bureau on non-response follow-ups

Boundary Verification Program

The Boundary Verification Program occurs in 2020 and provides the highest elected or appointed official of a local government or tribal chair of tribal government a last opportunity to review and comment on the boundary of their entity and address range breaks at the boundary before the 2020 Census data is tabulated.

Tentative schedule for Boundary Verification Program is included below:

January 2020 - Initial materials mailed to Highest Elected Official
March 2020 - Deadline for sending changes to be included in final phase
August 2020 - Receive certification from Highest Elected Official

2020 Master Address File (MAF)

The Master Address File is utilized by the U.S. Census Bureau to send questionnaires by mail and the success of the Decennial Census count depends on a high quality and complete of an address file as possible.

The U.S. Census Defines the Master Address File as:
The Census Bureau’s official inventory on known living quarters (HUs and GQ facilities) and selected non-residential units (public, private, and commercial) in the United States. The file contains mailing and location address information, geocodes, and other attribute information about each living quarters. The Census Bureau continues to update the MAF using the USPS Delivery Sequence Files and various automated, computer assisted, clerical, and field operations.
