NOTE: This table contains the weighted percent or weighted mean and the standard error. Cells with a small sample size (<30) are in red to indicate that the weighted estimates based on a small sample size are not reliable. Cells in italics indicate a coefficient of variation greater than 30 percent and numbers are not reliable. Cells with bold type indicate significant differences (p <.05) between disabled and nondisabled individuals.
