! Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 percent and 50 percent (i.e., the standard error is at least 30 percent and less than 50 percent of the estimate).

‡ Reporting standards not met. Either there are too few cases for a reliable analysis, or the coefficient of variation (CV) for this estimate is 50 percent or greater (i.e., the standard error is 50 percent or more of the estimate).

¹Principals were asked whether they were male or female. Although this variable is labeled “sex,” the questionnaire did not use either the term “gender” or “sex.”

NOTE: Data are weighted estimates of the population. Detail may not sum to totals because of rounding.
