Map Shows School Segregation Still Persists in California

An analysis by the Associated Press shows just how segregated schools in California truly are.

The data was collected as part of an AP study related to charter school demographics across the nation. However, KPCC has visualized the data for California on a map and the numbers are startling.

While segregation has been outlawed because of the landmark Brown v Board of Education case, de facto segregation continues due to a number of historic and systematic causes.

Here’s a link to the map of the California schools analyzed.

According to KPCC here’s the map explained:

"This map displays around 900 of the schools in California the Associated Press rated as the state's most racially isolated — meaning, schools in which a single racial group was heavily over-represented.

Using federal government data from 2014 and a U.S. Census methodology, the AP calculated a racial isolation measure — an "entropy" score — for every school.

These scores range from zero to one. A school with an entropy score of "zero" is entirely composed of a single racial group. A school with an entropy score of one would be evenly mixed between racial groups.

This map shows the 900 or so schools across California with entropy scores closest to zero, indicating one racial group essentially prevails there. Around 500 of these schools — charter, magnet and district-run — are located in Los Angeles, Orange, Riverside, San Bernardino and Ventura counties.

To view schools with higher entropy scores — and thus, more racially mixed student populations — adjust the slider on the bottom of the map. When a broader range is selected, the darker-colored dots represent more racially homogenous schools."
