From the abstract:
The number of poor adults age 65 and older has declined dramatically since the official poverty rate was designed back in the 1960s. Today the federal government considers fewer than 1 in 10 older adults to be poor, compared with about 1 in 3 in the 1960s. These estimates show the share of people with insufficient income to meet basic living expenses, such as food and housing. However, substantial research shows that the official poverty measure no longer reflects the true resources or needs of older adults.
The lack of an accurate poverty measure for older adults hampers efforts to reform Medicare and Social Security, which face significant revenue shortfalls. Reform proposals often aim to reduce costs by combining benefit cuts with increased cost sharing for older adults. To target any cuts or increased costs to older adults with the greatest ability to pay, an accurate measure of economic well-being is critical.
