Stare at the following table, which gives population projections for the elderly in the United States, in millions.
Age Group 2007 2020 2030 65-74 19.3 32.3 38.8 75 + 18.6 22.5 33.3
Over the next twenty years, we are going to double the number of people aged 65-74, who get their health care paid for by Medicare. And we are going to nearly double the number of people aged 75 and up, where medical expenses get really high. The Medical Expenditure Panel Survey, for which the most recent data available are from 2007, shows average spending in the 75+ age group of $10,500 per person.
