WASHINGTON (AP) — The number of poor people in America is 3 million higher than the official count, encompassing 1 in 6 residents due to out-of-pocket medical costs and work-related expenses, according to a revised census measure released Wednesday.

The new measure is aimed at providing a fuller picture of poverty but does not replace the official government numbers. Put in place two years ago by the Obama administration, it generally is considered more reliable by social scientists because it factors in living expenses as well as the effects of government aid, such as food stamps and tax credits.
