The nation’s unemployment rate ticked up to a three-year high in August as more people started to re-enter the labor market in search of work amid increasing economic activity.

The jobless rate rose to 3 percent from 2.9 percent in July, the internal affairs ministry reported Friday, its highest since May 2017. The overall result matched the median forecast from analysts.

Before seasonal adjustment, the number of unemployed people increased 490,000 from a year earlier to 2.06 million. It topped two million for the first time since May 2017.
