Yulee-area historical tornado activity is below Florida state average. It is 39% smaller than the overall U.S. average. On 10/2/1994, a category F2 (max. wind speeds 113-157 mph) tornado 7.0 miles away from the Yulee place center injured one person and caused between $500,000 and $5,000,000 in damages.
An Urban Institute paper argued that what they referred to as upper middle class, or those with a three-person household income between to $100,000 and $350,000, has grown from 12.9% of the population in 1979 to 29.4% in 2014.
The lower middle class consists of mostly blue-collar workers who make just enough to distinguish themselves from the poor or lower class. The average income for lower middle-class households is $29,204 as of September 2012, compared with the lower-class average of $23,550 for a family of four.
