From crime rates to life expectancy to income levels, statistics at the national level are next to useless when it comes to measuring the daily lives of ordinary people in the United States. This is because the United States — which is a huge and geographically diverse country — is simply too large to be summed up in a single number. This sort of generalizing is inappropriate for pretty much any place that’s larger than a single metro area, but it’s especially bad when applied to a place like the United States. Even the larger European countries are much smaller, more compact, and less diverse than US.

The importance of looking at things on a more local level is perhaps most important when looking at issues of homes and home prices. After all, even people who have never studied housing know that housing tends to be highly dependent on local issues, such as climate, local amenities, and access to employment. Many people already know that a four bedroom house in a nice Cleveland suburb is dirt cheap compared to a house of the same size in, say, San Diego, California.

So, it shouldn’t be terribly surprising to find that in many parts of the United States, buying a home continues to be quite affordable by historical standards. This fact has started to attract some attention in recent years. In her column titled “Opting Out of Coastal Madness to Live a Low-Overhead Life,” Anne Trubek discusses how its possible to live comfortably on $40,000. But here’s the rub. To do this, one has to live in an un-sexy midwestern city — albeit in a neighborhood with tree-lined streets and solid, four-bedroom houses.

Statistical data seems to bear this out as well. In June, the Brookings Institution released a new study showing that housing affordability varies greatly from coastal cities to the American interior. And by coastal, they mean “ocean coast.” Living near the coastline of the Great Lakes apparently brings with it even more affordability:

The basic premise of the research is to analyze affordability based on the fact that “U.S. median house prices have been roughly 2.5 to 4 times median income.”Comparing current home prices to incomes in each area, the report concludes:
