Description: The neighborhoods shown in this dataset are derived from a larger dataset drawn and maintained by the Data Desk, a team of Times reporters and Web developers in downtown L.A. The boundaries have expanded and shifted over time and now cover all of Los Angeles County broken down into 272 neighborhoods.This version of the LA Times boundaries only includes neighborhoods fully or partially within the City of Los Angeles. Neighborhoods that extend into other cities have been clipped to only show the portion(s) of the neighborhoods that are within the City of Los Angeles.Data Source: Los Angeles Times' Mapping LA project.Last Updated: October 7, 2016Refresh Rate: Never - Historical data (Note: should the LA Times update their Mapping LA project with new boundaries in the future, a new LA-specific layer will be added to the GeoHub as well.)

This layer is a filtered version of the Los Angeles Times neighborhood boundaries that only includes boundaries of neighborhoods fully or partially within the City of Los Angeles.

The Mayor’s Office utilizes the most recent data to inform decisions about COVID-19 response and policies. The Los Angeles COVID-19 Neighborhood Map visualizes the cases and deaths across 139 neighborhoods in the city. It includes the same data used by the office to spot changes in infection trends in the city, and identify areas where testing resources should be deployed.Data Source:Data are provided on a weekly basis by the LA County Department of Public Health and prepared by the LA Mayor's Office Innovation Team. The data included in this map are on a one-week lag. That means the data shown here are reporting statistics gathered from one week ago. This map will be updated weekly on Mondays.

The Los Angeles Index of Neighborhood Change is a tool that allows users to explore the extent to which Los Angeles Zip Codes have undergone demographic change from 2000 to 2014. Created in 2015/2016, the data comes from 2000, 2005, 2013, and 2014. Please read details about each measure for exact years.Index scores are an aggregate of six demographic measures indicative of gentrification. The measures are standardized and combined using weights that reflect the proportion of each measure that is statistically significant.Measure 1: Percent change in low/high IRS filer ratio. For the purposes of this measure, High Income = >$75K Adjust Gross Income tax filer and Low Income = <$25k filers who also received an earned income tax credit.

The File Wijk- en Buurtkaart 2012 contains the geometry of all municipalities, districts and neighborhoods in the Netherlands, with a number of statistical key figures as an attribute. The boundaries of districts and neighborhoods are based on what the municipalities pass on to Statistics Netherlands. The municipal boundary comes from the BRK of the Land Registry. This third version contains part of the key figures. After this version, no new version will be published for 2012.

Serious violent crimes consist of Part 1 offenses as defined by the U.S. Department of Justice’s Uniform Reporting Statistics. These include murders, nonnegligent homicides, rapes (legacy and revised), robberies, and aggravated assaults. LAPD data were used for City of Los Angeles, LASD data were used for unincorporated areas and cities that contract with LASD for law enforcement services, and CA Attorney General data were used for all other cities with local police departments. This indicator is based on location of residence. Single-year data are only available for Los Angeles County overall, Service Planning Areas, Supervisorial Districts, City of Los Angeles overall, and City of Los Angeles Council Districts.Neighborhood violence and crime can have a harmful impact on all members of a community. Living in communities with high rates of violence and crime not only exposes residents to a greater personal risk of injury or death, but it can also render individuals more susceptible to many adverse health outcomes. People who are regularly exposed to violence and crime are more likely to suffer from chronic stress, depression, anxiety, and other mental health conditions. They are also less likely to be able to use their parks and neighborhoods for recreation and physical activity.For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

The practice of redlining was codified by a series of maps created as part of the New Deal by the Home Owners’ Loan Corporation, which evaluated the mortgage lending risk of neighborhoods.

This layer shows all incorporated and unincorporated areas of Los Angeles County. The incorporated city boundaries are maintained by the Department of Public Works as part of the cadastral landbase, and reflects the most current annexations as of the date listed below. The unincorporated areas are maintained by the Department of Regional Planning (aka LA County Planning) for land use planning efforts. This is especially important as it relates to the County's General Plan and various area, community, and neighborhood plan updates. Please see relevant links below for more related information:Department of Regional Planning (LA County Planning) - About page.Link to official Public Works City boundary layer (shows all cities and unincorporated area, but not the individual unincorporated communities as recognized by LA County Planning).Link to official Public Works City Annexations layer and web application.Link to Countywide Statistical Areas layer (jurisdictions broken down by neighborhood boundaries for the purpose of reporting statistics)LAST UPDATED: 4/9/25 for several changes related to the South Bay and Westside Area Plan updates. These updates took effect on 4/10/25, and specific changes are listed below:Del Aire -> Split by El Segundo Blvd - Del Aire to the north, and Wiseburn to the south (South Bay Area Plan).Alondra Park -> Alondra Park / El Camino Village; Westfield -> Westfield / Academy Hills (South Bay Area Plan).West Fox Hills -> Del Rey (Westside Area Plan).

Population by age groups, race and gender, and the poverty by race is attached to the split tract geography to create this split tract with population and poverty data. Split tract data is the product of 2020 census tracts split by 2023 incorporated city boundaries and unincorporated community/countywide statistical areas (CSA) boundaries as of July 1, 2023. The census tract boundaries have been altered and aligned where necessary with legal city boundaries and unincorporated areas, including shoreline/coastal areas. Census Tract:Every 10 years the Census Bureau counts the population of the United States as mandated by Constitution. The Census Bureau (https://www.census.gov/)released 2020 geographic boundaries data including census tracts for the analysis and mapping of demographic information across the United States. 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.

The Los Angeles Clean Streets Index, the first-of-its-kind, is a grading system of every street in Los Angeles. The Bureau of Sanitation drove and scored over 9,000 miles of streets and alleys - each segment received a "cleanliness score" from 1-3. Each street score is based on four factors: litter, weeds, bulky items and illegal dumping. This assessment will be repeated every quarter. Los Angeles is leading the way as the only big city in the US conducting a regular cleanliness assessment of every City street.

The maps were produced with the Moringa chain developed by CIRAD (UMR TETIS). They are distributed in ESRI SHAPE vector format. The Moringa chain produces land cover maps by classifying satellite images. It implies a time series of Sentinel 2 images, a Digital Terrain Model, a very high spatial resolution satellite image (THRS), and a field reference database. We produced maps with VHSR images acquired, on one hand, by Spot 6/7 (1.5m/pixel) and, on the other hand, by Pléiades (50cm/pixel), to study the respective contribution of these data in this type of landscape. This sheet therefore contains maps produced with Spot 6/7 and Pleiades at each different precision level of the nomenclature: The most detailed level, labelled Code2, is composed of 12 classes. The basic level, labelled Code1, is composed of 8 classes. The level labelled Code0 is a proposal of slightly different distribution of classes at the same level than Code1. It is composed of 7 classes. In all the maps, we added the roads from the Open Street Map database. A detailed report of the techniques used for the production of these maps is available (See below "Related Publication"). This report contains in particular the validation statistics of the maps, which quantify the global and by class validity of the results. Les cartes ont été produites avec la chaine Moringa développée par le Cirad (UMR TETIS). Elles sont diffusées au format vecteur ESRI SHAPE. La chaine Moringa produit des cartes d’occupation du sol en classifiant des images satellites. Elle intègre une série temporelle d’images Sentinel 2, un modèle numérique de terrain, une image satellite à très haute résolution spatiale (THRS) et une base de données de référence terrain . Nous avons produit des cartes avec des images à THRS Spot 6/7 (1,5m/pixel) d’une part et Pléiades d’autre part (50cm/pixel), afin d’étudier l’apport respectif de ces données dans ce type de paysage. Cette fiche contient donc des cartes produites avec Spot 6/7 et Pléiades à chacun des différents niveaux de précision de la nomenclature : Le niveau le plus détaillé, intitulé Code2, est composé de 12 classes. Le niveau de base, intitulé Code1, est composé de 8 classes. Le niveau Code0 est une proposition de regroupement légèrement différente des classes au même niveau que celui du Code1. Il est composé de 7 classes. Dans toutes les cartes, nous avons ajouté les routes issues de la base de données Open Street Map. Un rapport détaillé des techniques utilisées pour la production de ces cartes est disponible (Cf. ci-dessous "Related Publication"). Ce rapport contient notamment des statistiques de validation des cartes qui quantifient la validité globale, mais également par classe, des résultats obtenus.
