Description: This data is the 2024 incorporated city boundaries and unincorporated community/countywide statistical areas (CSA) boundaries.  City Boundary:City Boundary data is the base map information for the County of Los Angeles. These City Boundaries are based on the Los Angeles County Seamless Cadastral Landbase. The Landbase is jointly maintained by the Los Angeles County Assessor and the Los Angeles County Department of Public Works (DPW). This layer represents current city boundaries within Los Angeles County. The DPW provides the most current shapefiles representing city boundaries and city annexations. True, legal boundaries are only determined on the ground by surveyors licensed in the State of California. Countywide Statistical Areas (CSA):The countywide Statistical Area (CSA) was defined to provide a common geographic boundary for reporting departmental statistics for unincorporated areas and incorporated Los Angeles city to the Board of Supervisors. The CSA boundary and CSA names are established by the CIO and the LA County Enterprise GIS group worked with the Los Angeles County Board of Supervisors Unincorporated Area and Field Deputies that reflect as best as possible the general name preferences of residents and historical names of areas. This data is primarily focused on broad statistics and reporting, not mapping of communities. This data is not designed to perfectly represent communities, nor jurisdictional boundaries such as Angeles National Forest. Low and Moderate Data:The low- and moderate-income summary data (LMISD) based on the American Community Survey 2016-2020 5-year estimates(2020 ACS) published by U.S. Department of Housing and Urban Development HUD). Data Field:UniqueID: ID field (combination of 2020 census tract number, 2024 city/community and 2021 supervisorial District number)COMMNAME: Legal city name or unincorporated area nameLOW: Number of persons with family income less than 50% of the Area Median Income (AMI)MOD (moderate): Number of persons with family income at least 50% but less than 80% of the AMILOWMOD: Sum of LOW and MOD / number of persons with family income less than 80% of the AMILOWMODUNIV: Number of persons with the potential for being deemed LOW or MOD. Use as denominator for calculating percentagePOP_TOT: Number of people from 2020 ACS 5YR Summary File (TabID B01001)  Data created: 2024 August:
