* Change is significant at the 90 percent confidence level relative to the prior year indicated. To ensure accuracy and consistency, Georgetown CCF calculates the coefficient of variation (CV; also known as the relative standard error) for each estimate. Estimates with CVs greater than 25 percent are not presented in this analysis. As a consequence, some states are excluded entirely from the above table and others have only one estimate present. For more information on suppression rules, see the methodology section.
