Here I have mapped the cost of owning a home as % of household income (taken from the 2000 Census). This is calculated by dividing the median cost of owning a home by the household income for a given area. If you would like to see a more detailed version go to Social Explorer and choose "Housing" from the second drop down then "Median Owner Costs: % of Income" and select the magnifying glass to zoom in on a specific county.
