This map shows a snapshot of the percentage of homes built in 1939 or earlier across different areas of your town.
Today, the largest concentration of prewar homes for sale is in New England and upstate New York.
For some homebuyers, part of the appeal of prewar architecture is that it came before the time of mass production. As a result each home has its own character.
The data are from the United States Census Bureau's 2011 American Community Survey. These values are an estimate for 2011 taking into account 60 months of collected data. You can learn more about the survey here.
Using your cursor, you can hover over any census tract – the geographic region defined by the U.S. Census – and see the percentage of prewar homes in the box in the upper right hand corner of the map.
