Conducted every two years, state officials provide updates and corrections to school district names, boundaries, identification numbers, and grade ranges. This is vital to education funding because the information obtained by the review program is used to aggregate the number of children aged 5 through 17 in low-income families in those districts, and that number is the basis for allocating Title 1 funds across the country.
In addition, the U.S. Census Bureau tabulates decennial census data by school district geography, providing one of the largest single sources of children's demographic characteristics currently available.
