Four data tables illustrate how school enrollment in the United States in 1990-91 compares with that of 1991-92. The first table lists, alphabetically by each state, public school enrollments for the 1990-91 and 1991-92 school years, along with the variance between the two years and the percentage of variance. The total enrollment for 1990-91 was 41,073,778 and that for 1991-92 was 41,815,944. The second table lists, in descending order by the variance between the two years, the enrollment increases (of 1,000 students or more) of 180 counties, ranging from a variance of 41,351 to 1,005. The third table lists, in descending order by the variance between the two years, county enrollment decreases of 1,000 students or more for seven counties nationwide. The variance for these counties ranged from 3,072 to 1,343. The fourth table lists, in decreasing order of the variance between the two years within each state, county enrollment variances (either a gain or loss) for 187 counties. (SLD)
