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. See supplemental note 11 for more information.
|
2 The NCES Comparable Wage Index (CWI) was used to adjust for geographic cost differences for 1997–98, the first year that it is available, through 2004–05. For more details on the CWI, see supplemental note 11.
|
NOTE: Detail may not sum to totals because of rounding. Public elementary and secondary unified districts are those districts that serve both elementary and secondary grades. In 2004–05, approximately 91 percent of all public elementary and secondary school students were enrolled in unified school districts.
