The boundaries displayed on this map have been generalized to simplify the ACO boundaries. Some very small areas have been eliminated and some ACO areas have been combined into a range of ACO areas. LEGEND TYPE of ENUMERATION AREA (TEA) 2355 Area Census Office (ACO) International/State Coastline Regional Census Center ATLANTA Self-Response (TEA 1) Update Enumerate (TEA 2) Update Leave (TEA 6) Remote Alaska (TEA 4) This depiction of TEAs combines Military TEA (TEA 5) with Self-Response (TEA 1) in all areas except Alaska and Puerto Rico, where it combines Military TEA with Update Leave (TEA 6). The U.S. Census Bureau uses Type of Enumeration Area (TEA) as the approach to conducting the 2020 Census for housing units in a given geographic area. The TEA assignment is based on area characteristics to maximize respondent participation. The percentages below are an estimate of the number of housing units in each TEA. The TEA delineation was conducted in 2018. Housing Unit Percent Total Type of Enumeration Area 95.32% Self-Response 4.48% Update Leave 0.17% Military 0.01% Update Enumerate 0.02% Remote Alaska Self-Response is designed to occur in areas where the majority of housing units have mail delivered to the physical location of the housing unit. Self-Response is the primary enumeration methodology for the 2020 Census. Military enumeration is designed to occur in areas on military installations. Update Leave (UL) is designed to occur in areas where the majority of housing units either do not have mail delivered to the physical location of the housing unit, or the mail delivery information for the housing unit cannot be verified. Update Enumerate (UE) is designed to occur in areas where the initial visit requires enumerating while updating the address frame. UE will occur in areas that were part of the 2010 Census Remote UE Operation, such as northern parts of Maine and southeast Alaska, as well as select American Indian areas that request to be enumerated in person during the initial visit. Remote Alaska (RA) is designed to occur in areas where the initial visit requires enumerating while updating the address frame. The majority of the operation will occur in remote geographic areas that have unique challenges associated with accessibility in Alaska. 2020 CENSUS TYPE OF ENUMERATION AREA
