DENVER — Colorado added a record 44,740 new corporations, nonprofits and other entities filed during the first quarter of 2021, but lagged behind the national average in employment. Initial filings were up 29.2% from the previous period and renewals grew by 1%, a positive sign for the pandemic recovery effort, according to the Quarterly Business and Economic Indicators report from Colorado Secretary of State Jena Griswold and the Leeds Business Research Division at the University of Colorado. However, nagging unemployment remains a concern. Colorado’s unemployment rate is 6.4%, higher than the 6% national average and good for 34th best in the country. Also of concern is the record-high 10,658 business dissolutions during the first quarter.
