| 1 The Theil coefficient measures variation for groups within a set (i.e., states within the country) and indicates relative variation and any differences that may exist among them. It can be decomposed into components measuring between-state and within-state variation in expenditures per student. It has a minimum value of zero and increasing values indicate increases in the variation, with a maximum value of 1.0. For more information about the variation in expenditures per student and the Theil coefficient, see supplemental note 10. |
| NOTE: Detail may not sum to totals because of rounding. Some data have been revised from previously published data. Public elementary and secondary unified districts are those districts that serve both elementary and secondary grades. In 2005–06, approximately 91 percent of all public elementary and secondary school students were enrolled in unified school districts. For more information about the classifications of expenditures for elementary and secondary education, see supplemental note 10. For more information about the Common Core of Data (CCD), see supplemental note 3. |
