The U.S. Payroll to Population employment rate as measured by Gallup, was 44.8% in September, similar to the 44.9% in August.

This percentage of Americans employed full time for an employer in September is among the highest in any September since Gallup began tracking P2P in January 2010, exceeded only by 45.1% in September 2012.

Gallup's P2P metric tracks the percentage of the U.S. adult population aged 18 and older who are employed by an employer for at least 30 hours per week. P2P is not seasonally adjusted. However, because of seasonal fluctuations, year-over-year comparisons are often helpful in evaluating whether monthly changes are attributable to seasonal hiring patterns or true growth (or deterioration) in the percentage of people working full time for an employer.

The September P2P rate is generally lower than rates in the summer months of June, July and August each year, as seasonal work slows down and many younger adults return to school.

The latest results are based on Gallup Daily tracking interviews with 29,323 Americans, conducted Sept. 1-30 by landline telephone and cellphone. Gallup does not count adults who are self-employed, work fewer than 30 hours per week, are unemployed or are out of the workforce as payroll-employed in the P2P metric.

Gallup's seasonally adjusted U.S. unemployment rate -- the closest comparison it has to the official numbers released by the BLS -- improved more than half a percentage point in June. This decrease was due primarily to the shift from an upward seasonal adjustment Gallup used in May to a downward adjustment in June. The underlying unadjusted unemployment rate was basically flat from May to June.

The unemployment rate as reported by the BLS each month does not always track precisely with the Gallup estimate, in large part due to differences in the adjustment procedure the BLS uses, and because of other methodological differences between the two surveys.
