AUGUSTA – Labor market conditions remained positive throughout most of the state in September.

Seasonally Adjusted Statewide Estimates

Household Survey Estimates – The preliminary seasonally adjusted unemployment rate estimate of 3.3 percent for September was little changed from 3.2 percent for August and unchanged from one year ago. The number of unemployed was little changed over the year at 23,200. Maine’s unemployment rate has been below 4.0 percent for 34 consecutive months, the longest period on record.

The U.S. preliminary unemployment rate of 3.7 percent for September was down from 3.9 percent for August and 4.2 percent one year ago.

The New England average unemployment rate for September remained 3.6 percent, with New Hampshire 2.7 percent, Vermont 2.9 percent, Massachusetts 3.6 percent, Rhode Island 3.9 percent, and Connecticut 4.2 percent.

The employment to population ratio estimate of 61.6 percent remained above the 60.4 percent U.S. average.


Payroll Survey Estimates – The 628,700 preliminary nonfarm payroll jobs estimate for September was up 4,500 from one year ago. The private sector estimate was up 4,100 to 528,000, with gains primarily in the healthcare, hospitality, and manufacturing sectors. Government jobs were up 400 to 100,700. Much of the gain was at the federal government-owned Portsmouth Naval Shipyard.

Not Seasonally Adjusted Substate Estimates

The not seasonally adjusted statewide unemployment rate estimate of 3.0 percent for September was up slightly from 2.8 percent one year ago. Unemployment was lowest in Sagadahoc and Hancock Counties (2.4 percent) and highest in Somerset County (4.3 percent).

Among metro areas, the unemployment rate was below the statewide average in the Portland-South Portland area (2.5 percent) and close to the average in the Lewiston-Auburn and Bangor areas (both 3.1 percent).

  1. Preliminary labor force estimates, including rates (labor force participation, employment, and unemployment rates), and levels (labor force, employed, and unemployed) tend to move in a direction for several months and then reverse course. Those directional trends are largely driven by a smoothing procedure and may not indicate a change in underlying workforce conditions. Annual revisions (published in March each year) tend to moderate or eliminate those directional patterns. A comparison of 2017 preliminary and revised unemployment rate estimates is available at .
  2. The 90 percent confidence interval for statewide unemployment rates in 2018 is 0.5 to 0.7 percentage points above or below the published estimate each month.
  3. To assess employment growth, we recommend looking at nonfarm jobs from the payroll survey rather than resident employment from the household survey. The payroll survey is larger, has smaller margins of error, and is subject to smaller revisions. More on the differences in accuracy of the two measures is at .
  4. Nonfarm payroll jobs estimates tend to be volatile from month to month because there is variability in the sample of reporting employers and their representativeness for the universe of all employers. Additionally, seasonal adjustment is imperfect because weather, the beginning and ending of school semesters and holidays, and other events do not always occur with the same timing, which can exacerbate monthly volatility. Users should look to the trend over multiple months rather than the change from one specific month to another. Estimates for the period from October 2017 to September 2018 will be replaced with actual payroll data in March 2019. Those benchmark revisions are likely to show less volatility than preliminary estimates.
