What drives Houghton’s History grade
On its age, its old homes and the National Register, Houghton is more historic than 89% of U.S. towns, #71 of 701 in Michigan. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.
A
HistoryA character grade: shown, never part of Houghton’s overall grade.
Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Houghton’s 59.0 sits above most of its state (91% of Michigan towns have fewer) while its 50 historic buildings outnumber those of 85% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A. The pre-1940 share is a Census survey estimate (±5.7 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1854.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

Native Americans mined copper in and around what would later be Houghton thousands of years before European settlement. "French explorers had noted... [its] existence [in the area] as early as the seventeenth century, [and in] 1772 Alexander Henry had prospected for copper on the Ontonagon River near Victoria."
Many Cornish and Finnish immigrants arrived in the Houghton area to work in the copper mines in the mining boom that made Copper Country on the Keweenaw Peninsula; both groups have had a great influence on the culture and cuisine of the local area. The Finns and others called much of the area Copper Island. Smaller numbers of French-Canadian immigrants moved to Houghton, while more of them settled elsewhere in Houghton County.
