School District State Map Series

Overview

This page-size map series is organized by state and uses data from the Small Area Income and Poverty Estimates. The maps display percent of school-age children in poverty at the school district level. Additional characteristics displayed for the state-level are poverty by metropolitan and micropolitan areas and median household income.

School District Geography

The school district maps display a composition of unified and elementary districts only. Secondary school districts were omitted because often they have the same boundaries as elementary districts. Cartographic generalization was applied to simplify and smooth line work, therefore, shapes may not represent exact boundaries and extent of districts. For an official map of school district boundaries, refer to the TIGER database listed in the Data Sources section below.

Data Classification

The natural breaks classification method was used to determine class breaks. The natural breaks method maximizes between class differences but minimizes within-class differences to ensure dissimilar values are separated into different categories. Natural breaks were determined at the national level so any individual state may not have all the categories present. The class breaks were then adjusted to align with national values to aid with visual comparisons.
