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 upper middle class is a sociological concept referring to the social group constituted by higher status members of the middle class. This is in contrast to the term lower middle class, which is used for the group at the opposite end of the middle class stratum, and to the broader term middle class. There is considerable debate as to how the upper middle class might be defined.
