Data for objectives 28-8a, 28-11a, b, and c, 28-13c and d, 28-14c, and 28-16b are unavailable or not applicable. Objective 28-15 was deleted at the midcourse.

Years in parentheses represent the baseline data year and the most recent data year (if available).

Disparity from the best group rate is defined as the percent difference between the best group rate and each of the other group rates for a characteristic (for example, race and ethnicity). The summary index is the average of these percent differences for a characteristic. Change in disparity is estimated by subtracting the disparity at baseline from the disparity at the most recent data point. Change in the summary index is estimated by subtracting the summary index at baseline from the summary index at the most recent data point. See Technical Appendix for more information.

The best group rate at the most recent data point.		The group with the best rate for specified characteristic.		Most favorable group rate for specified characteristic, but reliability criterion not met.		Best group rate reliability criterion not met.
	Percent difference from the best group rate
Disparity from the best group rate at the most recent data point.		Less than 10 percent or not statistically significant		10-49 percent		50-99 percent		100 percent or more
			Increase in disparity (percentage points)
Changes in disparity over time are shown when the change is greater than or equal to 10 percentage points and statistically significant, or when the change is greater than or equal to 10 percentage points and estimates of variability were not available.				10-49		50-99		100 or more
			Decrease in disparity (percentage points)
				10-49		50-99		100 or more
Availability of data.		Data not available.		Characteristic not selected for this objective.
