“The price to income ratio is the basic affordability measure for housing in a given area. It is generally the ratio of median house prices to median familial disposable incomes, expressed as a percentage or as years of income”
Rich used per capita income, not median family disposable income. I know he also used the OFHEO data, and now the Case-Shiller index.
I don’t know of anyone else who charted this by city.
