General Notes: *Median value gives the value for the "average" county for this metric, the 50th percentile of all counties reporting data. ** Students eligible to participate in the Free Lunch Program under the National School Act. The Free Lunch program provides cash subsidies for free and reduced-price lunches to students based on family size and income criterion. Public schools and public charter schools are sometimes administered out-of-state. SAGE Publications has excluded enrollment totals from those schools because they do not neatly fall under the umbrella of a county within the state that administers them, thus rendering county enrollment totals unreliable for comparison purposes. Data from some reporting schools in Alaska prior to 1992 were excluded due to complications involving changing geographic boundaries. Data as reported by each school. Starting with 2011 data, a *** indicates the data are not applicable, missing, or do not meet NCES data quality standards.
