the video at https://www.perforce.com/company/our-culture tells a different story, but as of the 2010 census, Minnesota was 85% white. You definitely see that in the Minnesota office.
Most of those videos were taken in the Minneapolis office, but some of them were taken in the California office.
Fun fact: "From the 19th century until about 1950, Minneapolis hovered around 99.0% white."
