Most people who lived in the cities of Fairhaven and New Whatcom in 1900 were born in another country, or had foreign parents.

Scandinavians started moving to the Puget Sound area at the end of the 19th century after initially settling in other states, such as Minnesota, Wisconsin, Illinois and Iowa.

In the 2000 census, the biggest places of ancestry for Bellingham residents were Germany, Great Britain, Ireland, Norway and Sweden.
There were more people claiming ancestry from each of these places than total Asians. All but Swedish ancestry outnumbered Hispanics.
Bellingham's foreign-born population is much smaller these days, and includes more Asians and Europeans.
