2011 Tuscaloosa–Birmingham Tornado

The 2011 Tuscaloosa–Birmingham tornado was an EF4 multiple-vortex tornado that destroyed portions of Tuscaloosa and Birmingham, Alabama, as well as smaller communities and rural areas between the two cities, during the late afternoon and early evening of Wednesday, April 27, 2011.

More than 36,000 people residing in 831 census blocks were directly impacted by the EF-4 tornado that traveled for more than 80 miles in central Alabama on April 27, 2011. The census blocks that intersected the tornado damage swath, as identified by the National Weather Service, contained a 2010 Census population count of 36,629 as the tornado moved northeast through the cities of Tuscaloosa and Birmingham.

According to the latest Census Bureau statistics, the median housing value for owner-occupied homes for the city of Tuscaloosa, Ala., was $154,300. The median household income was $35,304. About 28 percent of the population lived in poverty. These data come from the 2009 American Community Survey 1-year estimates.

A census block is the smallest unit of geography for which the Census Bureau provides decennial census data and is bounded by visible features, such as streets, roads, streams, and railroad tracks, and by nonvisible boundaries, such as selected property lines and city, township, school district, and county limits and short line-of-sight extensions of streets and roads.
