The correct answer for: In the United States, people who live in urban areas have a life expectancy years longer than those who live in rural areas. Is: 3.5%

Explanation:

All right, to understand this question we need to recall 2005-2009 rural and urban census information. According to that study, the urban population lived 3.5% more than people in rural areas. To be honest this is not a very big gap. However, it was declared that most of the difference was because people who live in rural areas have less access to healthcare emergency services. Thus, that results in a very small GAP.
