A concerned group of citizens wanted to know if the proportion of armed robberies in Texas was differentin 2011 than in 2010. Their research showed that of the 113,231 violent crimes in Texas in 2010, 7,622 ofthem were armed robberies. In 2011, 7,439 of the 104,873 violent crimes were in the armed robberycategory.
