*

Weighted number of people reporting difficulty with item;

Percent disable (%D)= [(weighted disable count ÷ weighted total population) × 100] (Note: denominator available in Table 1);

95% Lower Confidence Limit (LCL)=[Disable − MOE];

§

95% Upper Confidence Limit (UCL)=[Disable + MOE];

#

Range of Uncertainty (RU) = {[(SE × 3) ÷ disable] × 100};

**

Number of responses to disability item which are assigned or changed (includes non-disable individuals);

††

Percent Allocated (%A)= [(weighted allocated count ÷ weighted total population) × 100] (Note: denominator available in Table 1)
