After a weak start to the year, hiring rebounded strongly in Colorado in February. But the number of people joining the labor force outpaced the number of jobs added, resulting in a slightly higher unemployment rate, according to a monthly update from the Colorado Department of Labor and Employment. The state lost a revised 700 jobs in January, reversing the initially reported gain of 800 jobs and putting Colorado in a group of only four states to suffer a decline in nonfarm payroll jobs that month. Those losses were likely caused by a colder and snowier start to the year, said Ryan Gedney, a senior economist with the CDLE on a press call Friday morning.
