Deschutes County’s unemployment rate in August reached a new all-time low of 3.7 percent, the Oregon Employment Department reported Tuesday.

All three Central Oregon counties posted record lows last month, the employment department said.

In Crook County, the unemployment rate remained unchanged for a third consecutive month at 5.4 percent. That’s down from 6.4 percent in August 2017. In Jefferson County, the unemployment rate was 4.8 percent, essentially the same as July but down from 5.7 percent a year ago.

The Deschutes County unemployment rate in August 2017 was 4.3 percent. This year the county shed slightly fewer jobs than is typical for August and experienced a hiring surge in construction.
