⁶Dividing the mobility limitation percentage point change among all single people by the percent receiving SSI (.46/.10) equals 4.6 percentage points. The approximate mobility limitation rate among the SSI population is 40 percent (it is 40 percent whether we look at those reporting SSI or those reporting below the twenty-sixth income percentile). This is about an 11 percent reduction for a $100 increase in the maximum benefit, or between a 15 percent and 20 percent increase in income among the very poorest elderly Americans (generally those falling below 90 percent of the poverty level).
