Geographic Region: School Districts, Elementary and Unit

School districts provide public educational services for their area’s residents.
The Census Bureau tabulates data for three types of school districts: elementary, secondary, and unified. Elementary school districts provide education to the lower grade/age levels, and secondary school districts serve upper grade/age levels. Unified school districts provide education to children of all school ages.

Data available on IECAM

The Data Hub presents eligibility and demographic estimates as well as program data (sites and capacity) by school district in a combined list of elementary and unit districts. Enrollment data is not yet available by school district. 

IECAM does not present data by secondary school district. Elementary and unit school districts are contiguous and don’t overlap. There are about 750 elementary and unit school districts in the state. Taken together, they cover the entire state.

School districts can change yearly as old districts combine or split, as new districts are created, and as elementary districts merge with secondary districts to form unit districts. Therefore, the number of school districts changes from year to year and school district X in one year may not cover the same geographic area as school district X the following year.

When a user searches for by year and by school district in the basic database search, IECAM presents results only for those school districts that existed in that year. When a user searches for school district data in a multiyear search on the IECAM database, IECAM presents results for all school districts that existed in any of the years selected. If the school district did not exist in one of the selected years, an indication such as “N/A” will appear in that particular table cell.
