The Labor Department reported Thursday that 367,000 filed first time jobless claims last week, an increase of 4,000 from the previous week’s revised figure of 363,000. The four-week moving average, a less volatile number that flattens out week-to-week fluctuations in the data, was 375,000, unchanged from the previous week’s revised average. The modest increase following a week when first-time claims for unemployment benefits dropped to a two-month low indicates a mild improvement in the labor market, analysts say. The number of Americans filing for continuing unemployment claims during the week ending Sept. 22 was 3,281,000, unchanged from the prior week. The four-week moving average was 3,285,250, a decrease of 12,750 from the prior week. States reported 2,143,049 persons claiming emergency unemployment benefits for the week ending Sept. 15, a decrease of 17,399 from the previous week. There were 3,027,447 claimants in the comparable week in 2011. The total number of people claiming benefits in all programs for the week ending Sept. 15 was 5,088,612, a decrease of 85,386 from the previous week. There were 6,859,096 persons claiming benefits in all programs in the comparable week last year. The largest increases in initial jobless claims for the week ending Sept. 22 were in Alabama, Kentucky, Michigan, Mississippi, and Ohio. The largest decreases were in California, Indiana, New York, North Carolina, and Virginia.
