The percent of those needing assistance in IADL only (instrumental activities of daily living) drops off quickly as level of education rises - 10.0% (1.6 million) for those with 8 years or less of education compared to 1.3% (481,000) for those with 16 or more years of education. The same trend occurs for those needing assistance in ADL (activities of daily living), dropping from 6.1% (1,002,000) to 0.7% (265,000), respectively. It should be recognized that there is a lower probability of advanced education in older citizens at this time. Therefore, some of the difference can be attributed to the influence of age.
