Blocks are typically bounded by streets, roads or creeks. In cities, a census block may correspond to a city block, but in rural areas where there are fewer roads, blocks may be limited by other features. The Census Bureau established blocks covering the entire nation for the first time in 1990.There are less number of Census Blocks within Los Angeles County in 2020 Census TIGER/Line Shapefiles, compared in 2010.Updated:1.

This resource is a member of a series. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) System (MTS). The MTS represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads shapefile includes all features within the MTS Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in the MTS that begins with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

This layer contains the 2011 Official Supervisorial District Boundary for the County of Los Angeles, drawn at the parcel level, per Assessor parcels and the County Cadastral Landbase.Supplemental Information: Adopted September 27, 2011 – Another entry on this portal includes redistricting information from the Districts’ adoption in 2011, along with boundaries drawn at the TIGER street map level. Per Sec. 21500 of the California Elections Code, Supervisor District boundaries are adjusted following each decennial federal census. Published in the County Code under Title 1, Chapter 1.08, boundary descriptions are based on census tracts and city boundaries at the time of adoption.Metes and Bounds descriptions were prepared by the Department of Public Works.2010 Census Blocks provide more information and GIS data downloads on this portal. Census tracts listed in the County Code correspond to the first six digits of the GIS attribute CTCB10.City Boundaries and City Annexations provide current and historical legal city boundary information on this portal.

The LA County 2021 Redistricting WebApp provides an interactive platform that allows users to explore the changes in supervisorial district boundaries between the 2010 and 2020 redistricting efforts. The app visually compares the old and new district maps, highlighting shifts in geographic adjustments and the impact on political boundaries. Users can toggle between the 2010 and 2020 maps to see how population changes and community needs influenced the redrawing of district lines, ensuring fair and equitable representation across the county.

This data was created by combining the 2010 Census Block Group file as well as the Legal City Boundaries maintained by the LA County Department of Public Works.In reviewing this overlap, LA County aligned a fairly large number of block group boundaries to city boundaries where those boundaries were identified as being incorrectly misaligned by the Census Bureau. This removed split block groups that did not have any population assigned to them.To support the development of the Countywide Statistical Areas, some split block groups that had multiple parts were “unmerged” so that non-contiguous portions of the split block group could be assigned to different CSAs. Examples include areas of Unincorporated Quartz Hill and Lancaster that have 2 or more CSA names for a single split block group. Those portions are identified as “Parts” and tracked in the “Parts” field.In the City of Los Angeles, the LA City Neighborhood file was overlaid on the Block Groups and boundaries assigned using the centroid of the block group therefore, while the names of the CSAs in LA City match the neighborhood file, the boundaries are not the same.Field Descriptions:BG10 2010 Block Group (7 digits)CT10 2010 Census Tract (6 digits)FIPxx 2010-2020 City Code (5 digit FIPS code - note that Unincorporated is 99037)CITY_TYPE "City" or "Unincorporated"LCITY Legal City NameCSA - Countywide Statistical Area Name (e.g. Community)LABEL Pretty name for LabellingSOURCE CSA sourceBG10FIPxx 2010 - 2020 Split Block Group (Block group and FIP code combined)CT10FIPxx 2010 - 2020 Split Tract (Tract and FIP code combined)DISTRICT 2011 Supervisorial DistrictNOTES Notes relevant to the geographyPART Part number (for non-contiguous split block groups)PARTS Total number of non-contiguous parts (for non-contiguous split block groups)CSA_ID Unique BASA ID - combination of 2016 Split Block Group and Part NumberMERGED Flag if the Split BLock Group was merged into multi-part shapesCITYCOMM - merged values for the legal city, community, and supervisorial districtREMARKS - additional remarks about the source of any changes.

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.
