This memorandum documents specific updates that have been made to the plan for the Geographic Programs Operation (GEOP)—Geographic Delineations (GD) component since the release of the Geographic Programs operation—Geographic Delineations Detailed Operation Plan (DOP) on December 31, 2018. The Geographic Delineations component of the Geographic Programs operation is responsible for the scope, schedule, and budget for the geographic delineations to support the 2020 Census. This includes the creation of collection and tabulation geographies and associated products. This component is responsible for the creation of the Special Land-Use areas, Basic Collection Units (BCUs), Type of Enumeration Areas (TEAs), and Field Management Areas that constitute collection geography. The tabulation geography consists of Tabulation Blocks, Urban Areas (UAs), and Zone Improvement Plan Code Tabulation Areas. The delineations of these areas are created to support 2020 Census data collection, dissemination, and products, such as the Master Address File Extract, map products, and Geographic Reference Files.
The changes to the baselined DOP and clarifications documented in this memorandum are based on continued planning and development to support the Geographic Programs operation for the 2020 Census. No changes to this operational component are related to the COVID-19 pandemic.
