National health spending will average more than $10,000 a person this year for the first time, the Obama administration said Wednesday, a milestone that heralds somewhat faster growth in health spending after several years of exceptionally low growth. By 2025, the administration reported, health care will represent 20 percent of the total economy, up from 17.8 percent last year. By 2025, one of every five Americans will be on Medicare, and the program will spend an average of nearly $18,000 a year for each beneficiary. Medicare spent about $12,000 per beneficiary in 2015.
