Veteran unemployment hit a record low in September, according to federal data released Friday.

Figures from the Bureau of Labor Statistics show a drop to 3 percent, compared to a 3.7 percent unemployment rate in August. This marks the lowest unemployment rate for the group since 2006, the earliest year for which data is publicly available.

Experts warn against putting too much stock in these numbers, however, as the veteran unemployment figures are drawn from a much smaller sample size than the overall population.

Unemployment among Iraq and Afghanistan-era veterans continued its downward trend to 3.9 percent — down from 4.2 percent in August. Nonveteran unemployment also decreased slightly.

While the national unemployment dipped 0.2 percentage points in September to 4.2 percent, the U.S. actually lost jobs over the previous month for the first time in seven years, The New York Times reports.

The Bureau of Labor Statistics attributes the overall loss of 33,000 jobs largely to Hurricanes Harvey and Irma. The natural disasters particularly affected employment in the food service and drink industries, which had added an average of 24,000 jobs each month over the last year.
