In some parts of the country, the housing stock is far older. On average, owner-occupied housing in New York, Massachusetts, and Pennsylvania is more than 50 years old. Though there are exceptions to the rule, homes tend to be older throughout the Northeast and Midwest, and in urban cores across the country.
By contrast, newer homes and bona fide new construction homes are more common in Southern and Western cities in general, and in suburban and exurban communities across the country.
