MONTGOMERY, Ala. (AP) — Alabama’s unemployment rate has dropped to an all-time low of 2.8%.

The state says the rate in April was down slightly from a month earlier and well below the national rate.

The preliminary, seasonally adjusted rate was 0.1% better than the rate in March. And it compares favorably to the U.S. jobless rate of 3.6% for April.

Shelby County in metro Birmingham had the state’s lowest unemployment rate at 1.4%, followed by Marshall County at 1.5%. Wilcox County in rural west Alabama was the worst in the state at 7.7% unemployment.
