Description:

Los Angeles County Health Districts (HDs), updated in 2022. Los Angeles County is divided into twenty-six HDs, which are subdivisions of Service Planning areas (SPAs). HDs are used for planning and managing health service delivery across Los Angeles County.

Updating HD and SPA boundaries to align with new U.S. Census Bureau census tract boundaries is performed after every Decennial Census.

How was this data created?

The 2020 Census Tracts from the U.S. Census Bureau's 2021 TIGER/Line were used as building blocks for the HD layer. The 2012 HD layer was compared to the 2020 Census Tracts layer to provide preliminary information on the HDs associated with each Census Tract and to determine where HDs no longer aligned. For the 2022 HD layer, boundaries were updated to align with 2020 Census Tract boundary changes within their corresponding 2022 SPAs with consideration for maintaining effective service delivery. The HDs were refined to conform with the County boundary and coastline from the Supervisorial Districts 2021 and County Boundary layers.
