Census tract is a small, relatively permanent statistical subdivision of a county delineated for the purpose of presenting data. Census tracts ideally contain about 4,000 people and 1,600 housing units.
The Census Bureau (http://www.census.gov/)maintains geographic boundaries for the analysis and mapping of demographic information across the United States. Every 10 years the Census Bureau counts the population of the United States as mandated by Constitution. The Census Bureau releases the results of this county as demographic data with geographic identifiers so that maps and analysis can be performed on the US population.There are little more Census Tracts within Los Angeles County in 2020 Census TIGER/Line Shapefiles, compared to 2010.UPDATED: March 2021How was this data created?This 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.Data Fields:1.
