Mobile Home Vulnerability
Of the more than 560 people killed in the U.S between 2001 and 2010 by tornadoes, 51 percent
were in mobile homes, according to the National Oceanic and Atmospheric Administration.
According to the 2012 Kansas Severe Weather Awareness Week packet, people living in mobile
homes are killed because of tornadoes at a rate 20 times higher than people living in permanent
homes. Only 33 percent of those who died were in permanent structures, and 16 percent were
outside a home.
Yet mobile homes make up only about 7 percent of the nation's housing. They represent about
5.2 percent of homes in Kansas, with 65,184 units according to the U.S. Census Bureau.
