The New York Times ran a story about the geography of the receipt of government payments in the country. It includes Social Security, Medicare, Medicaid, Income Support (food stamps, disability, EITC), Veterans Benefits, and Unemployment Insurance.
You can see
the interactive chart here. The
accompanying NYT article is here.
I zoomed the overall government benefits charts of Virginia for kicks, ran it from 1969 to 2009, and then pieced the pictures together so we could see them together for comparative purposes. If you click on the picture at the right, it will blow up so you can see it more easily.
If you're really curious, you can click on individual charts an isolate Social Secuirty, Medicare, Medicaid, etc. by jurisdiction.
As a preface, let me say that it drives me crazy when people lump all of Fairfax County together as one jurisdiction. Fairfax County is now larger than
eight states. Looking at the County as a whole always masks the issues in my district and it is really frustrating when this kind of information goes out. The same thing is true for Prince William County which has its pockets of have's and have not's notwithstanding its relative wealth overall.
For example, I was recently given data by the state that said 15% of my constituents are receiving Medicaid. Delegate Kory's district (near Bailey's Crossroads) is at 15%. The rest of Fairfax County is between 3% and 10%.
In terms of Virginia, there are probably different trends at work. Looking at the individual charts, the drivers are mainly increased percentages of Social Security, Medicare, and Unemployment Insurance.
