Any idea why the median income peaked in 1970?
The other information that intrigues me is the drop in unemployment in 2002 which don't seem correlated to the shrinking in manufacturing jobs. The graph alone doesn't really show whether those employed in manufacturing are city residents who work in suburban factories or if they work in factories located within the city limits. I'm sort of assuming it's the latter but it could really be either one. It also doesn't explain what other factors are probably affecting unemployment rates.
