This study was just released Oct 15, 2008, which is an update on how many people in the USA will be over 65 years old (and many of them chronically ill) in the next 20 years. It can be hard to find specific statistics so this is always wonderful when they are updated.
As I approach churches about the need for HopeKeepers groups and publishers about the need for encouraging resources (that point people toward the Lord!) during their difficulties of living with illness, hard statistics are always a huge benefit.
I hope you may find them of interest, and possible use, as well.
