Description: In 2014 and 2015, The LA County Enterprise GIS team under the Geographic Information Officer worked with the Unincorporated Area Deputies and Field Deputies of each Board Office to establish names that reflect the desires of residents. CSAs differ from the more informal Community geographies because:They are focused on broad statistics and reporting, not mapping of communities.They represent board approved names assigned to Census block groups and city boundaries.They cover the entire unincorporated County (no gaps).There are not overlapping areas. Additionally, CSAs use the following naming conventions:All names are assumed to begin with Unincorporated (e.g. Unincorporated El Camino Village) which will not be part of the CSA Name (so the name of the Statistical Area would be El Camino Village).Names will not contain “Island.” Beginning each name with Unincorporated will distinguish an area from any surrounding cities. There may be one or more exceptions for certain small areas (e.g. Bandini Islands)A forward slash implies an undetermined boundary between two areas within a statistical geography (e.g. Westfield/Academy Hills or View Park/Windsor Hills)Certain established names may include hyphens (e.g. Florence-Firestone)Aliases may be defined in parentheses (e.g. Unincorporated Long Beach (Bonner/Carson Park))The original set of names were derived from community names used in the 2011 Redistricting process, chosen with the assistance of the Board of Supervisors.Updates: 2026 February: CSA updated for East La Mirada CSA, merged into East Whittier CSA as per 2/4/2026 GIS Data Committee meeting decision.2026 January: CSA updated for Lancaster city annexation (effective date 12/10/2025).2025 August: CSA updated for San Gabriel city annexation (effective date 8/6/2025). 2025 April: CSA updated for Long Beach city communities. These community areas and names were reviewed and approved by the City of Long Beach - Community Development Department, Advance Planning Division on 3/26/2025. Contacts: Scott Kinsey <Scott.Kinsey@longbeach.gov>, Bradley Bounds <Bradley.Bounds@longbeach.gov>, Alejandro Sanchez-Lopez <Alejandro.Sanchez-Lopez@longbeach.gov>2025 March: CSA update for Duarte City annexation; and Arcadia City detachment and Monrovia City annexation (effective date 3/17/2025).2024 December: CSA data update to include Whittier City annexation (effective date 11/13/2024).2024 April: CSA data updated to include La Verne City annexation (effective date 4/1/2024).2023 December: CSA data updated to include "Unincorporated Charter Oak" (south of 10 Freeway) into "Unincorporated Covina".2023 June: CSA data was updated to include "Kinneloa Mesa" community, which was a part of Unincorporated East Pasadena.2023 January: Updated layer schema to include feature type (“FEAT_TYPE”) field, which can be one of land, water, breakwater, or pier (consistent with the City Boundaries layer).2022 December: CSA data was updated to incorporate the “Tesoro Del Valle” annexation to the city of Santa Clarita. Unincorporated Valencia is now completely annexed to the City of Santa Clarita. In addition to land area, this data also includes other feature types such as piers, breakwater and water area. 2022 September: CSA data was updated to match with city boundaries along shoreline/coastal area and minor boundary adjusted in some other areas.
