A new analysis of economic data conducted by the Independent Sector pegs the average value of volunteer service in 2016 at $24.14 an hour -- 58 cents more than 2015 and $1.07 more than 2014. According to the IS, the figure is based on the hourly earnings of all production and non-supervisory workers on private non-farm payrolls, based on yearly earnings provided by the Bureau of Labor Statistics. The IS takes that national average and makes adjustments to derive state-level values as well. For 2016, the value of volunteer service ranged from a low of $19.66 per hour in Arkansas up to a high of $39.17 per hour in the District of Columbia. For 2016, the group said, most states saw increases, although two -- New Mexico and Wyoming -- saw slight decreases year over year.
