The US Census Bureau's American Community Survey asked over 1 million Americans what language they speak most at home.

Colorado's most common language spoken, excluding English and Spanish, is German.

"Using individual-level responses from the 2017 American Community Survey assembled and published by the Minnesota Population Center's Integrated Public Use Microdata Series program, we found the most common language spoken at home in each state, excluding English and Spanish," said the Business Insider.
