According to the Dallas Business Journal, the U.S. Census Bureau recently released data from its American Community Survey, which ranked 83 major cities based on the percentage of old housing stock built before 1960.

Not surprisingly, Dallas and Fort Worth both ranked in the bottom half of the list. Dallas came in at No. 49 with 25.3 percent of its housing units dating back to pre-1960. Fort Worth followed with 25.2 percent. A significant portion of both city’s percentages can likely be traced to the post-war housing boom in the 1950s.

The rankings are confined to each individual city and do not include suburbs or other parts of the metro areas, and the Census Bureau’s broad definition of a housing unit encompasses every house, duplex, condominium, townhouse, apartment, and trailer. 

Buffalo, New York topped the list with 85.2 percent of its total housing stock built in 1959 or earlier. The other four cities in the top five are Detroit with 80.7 percent its housing units constructed before 1960; Cleveland with 77.5 percent, St. Louis with 77.3 percent, and Baltimore with 72.9 percent.

Plano came in at dead last on the list with only 1.1 percent of old housing stock, and it was narrowly preceded at the bottom by other former suburbs in the southwest and west that have grown into major cities.
