As with Payroll to Population rates, states in the Midwest — including North and South Dakota, Minnesota, Nebraska, and Iowa — were among those with the best underemployment rates in 2013.

Gallup’s U.S. underemployment rate combines the percentage of adults in the workforce that is unemployed with the percentage of those working part time but looking for full-time work. While P2P reflects the relative size of the population that is working full time for an employer, the underemployment rate reflects the relative size of the workforce that is not working at capacity, but would like to be.
