Child Opportunity Index 3.0-2023

The 2023 update of the Child Opportunity Index (COI 3.0) expands neighborhood-level data on children’s access to opportunity through 2023, incorporating enhanced indicators and improved data sources. This release refines measurement across 14 subdomains and standardizes values using the 2023 child population, offering a clearer picture of disparities in resources that shape children’s development. Because of methodological updates, results are not directly comparable to the earlier 2021 version.

Population with No High School Diploma

Layer displays information about the population with no high school diploma from the American Community Survey (ACS). Data from the 2008-2012 5-Year estimates is available at the state, county, ZCTA, PUMA and census tract geographic levels. For more data on educational attainment from the ACS, browse the Map Room data and navigate to Education>Attainment.

Educational Attainment, Disparity Index Score

Layer displays information about racial disparity of educational attainment using data from the 2009-2013 American Community Survey (ACS). The Index of Disparity (ID) is used to show the magnitude of variation in indicator percentages across population groups. In this case, the index measures the difference in the percentage of the population with less than a high school diploma across four racial and ethnic groups.

Missouri Community College Service Areas

This layer displays the service areas for the various community colleges in the state of Missouri. Unlike in some states, Missouri’s community colleges are not a “system” with a centralized administration under one governing body. Instead, they are 12 separate and independent local colleges, with a history of working together to meet both state and local needs. As local entities, each college’s academic and workforce training programs mirror the local economy by design. Their service regions cover the entire state, allowing them to serve every Missourian and every Missouri business.

Public Education Expenditures per Student

Layer displays information about public education finances. Data is from the National Center for Education Statistics (NCES) Common Core of Data (CCD) School District Finance Survey for fiscal year 2010. County-level data was generated by CARES by aggregating school-district level records with valid reported figures for total students and total expenditures.
