A Portrait of Los Angeles County, a report by Measure of America, is an in-depth look at how residents of America’s most populous county are faring in three fundamental areas of life: health, access to knowledge, and living standards. The Human Development Index – a composite measure of health, education and income – is the featured measure and is disaggregated by gender, race and ethnicity, gender by race and ethnicity, major Asian and Latino subgroups, and nativity at the county level. The index is also presented for 106 cities and unincorporated areas within the county, 35 City of Los Angeles Community Plan Areas and 15 City Council Districts. This dataset and the accompanying report is intended for policymakers, planners, service providers, advocates, journalists, students and anyone with an interest in exploring well-being outcomes among the many communities that make up Los Angeles County.

The CT00 layer contains polygons for census areas. The source for the information in this layer is the U.S. Bureau of the Census and appropriate county government agencies.
This file is extracted from the Los Angeles County Registrar/Recorder's Precinct Information File, which is designed to match the Thomas Brothers TRNL (road network) layer.
Where census boundaries are defined by streets, water, city boundaries, or other features, those arc segments are copied to the CT00 layer, so that census tracts and other layer features match perfectly.

2010 Census Blocks clipped to the County Boundary. A new field “COMMNAME” was added and populated with city and community names based on 2011 redistricting unit community names in the census block data.
