> State median household income: $46,472
> Poverty rate: 8.3%
> Oct. unemployment: 2.8%
> Major metro area: Birmingham-Hoover, AL

Alabama is one of the poorest states in the country. The state’s median annual household income of $46,472 is more than $11,000 below the U.S. median. Alabama also has one of the highest poverty rates of all states at 18%. The residents of Shelby County, which is located just south of Birmingham, tend to be much more affluent. Most households earn more than $74,000 a year, and just 8.3% of residents live in poverty. The county’s higher incomes are likely bolstered by a strong job market. The county’s unemployment rate of 2.8% is well below the state’s 4.1% unemployment rate.

Likely because of its relatively prosperity and strong job market, Shelby County’s population is growing at a faster pace than the state’s population growth rate.. In the past five years, the county’s population grew by 6.9%, more than four times the rate of Alabama’s population growth as a whole.

These workers, as well as many others in Juneau, are much more likely to be qualified for skilled professions.
