"NOTE: Each table contains the weighted percent or weighted mean, the standard error, and the sample size.   Estimates must be based on a sample > 30 and the coefficient of variation should be less than 30 percent.  Samples smaller than 30 are shaded and cells with a coefficient of variation greater than 30 percent are italicized.   Individual significance tests were conducted comparing the elderly with disabilities to 1.  Persons with disabilities aged 25-64, 2. Persons with disabilities < 25 years and 3.
