* Updates for this data series are not available since 2003.
Due to unusually high margin of error for these data, please compare the related data series, "Lower 95% of Confidence Interval for Percent of Population Lacking Basic Prose Literacy Skills" and "Upper 95% of Confidence Interval for Percent of Population Lacking Basic Prose Literacy Skills" for help in interpreting differences between counties. Only about 1 percent of the 1992 and 2003 county-level differences are statistically detectable because of the level of precision of the individual county estimates, indicating that it is not possible to state that the percentages of adults lacking BPLS changed over time in most counties.
Years Available: 1992, 2003

General Notes: *Median value gives the value for the "average" county for this metric, the 50th percentile of all counties reporting data. To compare two counties, compare whether the upper confidence interval for one county is lower than the lower confidence interval for the other counties, using the other data series found in SAGE Stats. If not, the difference between the two counties is not statistically significant. The raw numbers, provided here, give a general sense of data patterns but should be interpreted with caution.
