While there has been considerable change in rank by size within the 100 largest school districts over time, the lists of school districts in 1993–94 and 2003–04 are similar. Only 9 of the 100 largest school districts in 1993–94 were not among the 100 largest school districts in 2003–04 (see table D-4 for a list of the 100 largest school districts in 1993–94).10
Between 1993–94 and 2003–04, the number of students in the 100 largest school districts increased by 11 percent, the number of teachers increased by 43 percent, and the number of schools increased by 12 percent (table 4). However, while the numbers of students, teachers, and schools increased between these years, the proportion of the national total these numbers represent was essentially unchanged. For example, the 100 largest school districts included 23 percent of all students in both 1993–94 and 2003–04.
