Which states have more basements?

Basements are more commonly found in the Midwest. This is because when your home is first built, builders have to dig deep below the earth to place the footing below the freeze line so they already have dug a basement.  

Still, basements across the country are in decline. In 2000, 40% of homes were built on a basement, in 2013, the number dropped to 32%. 

One region in particular, the area west of the Mississippi River and east of the Rocky Mountains is where basements are most prevalent. In this area, the decline is not being seen and roughly 40% of homes are still being built with basements.  

States like Nebraska, Kansas, Oklahoma, and Iowa also utilize basements as a shelter in the event of a tornado.
