Description: 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: March 2021How This Data is Created?This census geographic file was downloaded from Census Bureau website: https://www2.census.gov/geo/tiger/TIGER2020PL/STATE/06_CALIFORNIA/06037/ on February 2021 and customized for LA County.

Similarly, "Feat_Type" field is added and populated with water, ocean and land values. Remaining two fields "SUP21" and "Pop20" will be populated later. Note: This data includes 3 NM ocean. However, user can use a definition query to remove those. Data Fields:1. STATE (STATEFP20): State FIP, "06" for California2. COUNTY (COUNTYFP20): County FIP "037" for Los Angeles County3.
