This could be an absolute number -- like there were 30 million in
1985, and  75 million in 2004....or a percentage, such as in 1990, 15%
of all workers were categorized at part-time while in 2004 that number
is 20%. Point I'm trying to support is that part-time work trends are
driving, to some degree, the problem of uninsured in America.
