Homes back East are older, and houses out West are newer, right? Not quite.

We looked at single-family houses built from 1900 to 2014 to see which decades are most represented by the current housing stock.Turns out, the largest share of homes in theNortheastern states was built in the ’80s, but in California the ’50s remains the dominant decade for homes still standing.

Meanwhile, Washington, DC, is holding strong as the area with the oldest decade – the 1920s – most represented today.
