There is no doubt that their median incomes are rising and that the proportion of them living below all the low-income cut-offs has declined substantially, no matter which measure you use.
Another measure to look at is net worth—asset levels, home ownership, and so on. I was surprised, looking at the figures on net worth among unattached women, but again over the last 15 to 20 years even net worth in terms of assets and wealth has also increased. Even when you look at income replacement rates, the proportion of women's income after retirement as a percentage of their pre-retirement income, again they have been generally comparable to men for some time. In terms of cost of living, the benefits are indexed to the cost of living once people are receiving them, so they do grow. The public benefits do grow.
