What drives Thompson’s History grade
On its age, its old homes and the National Register, Thompson is more historic than 29% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of Thompson’s overall grade.
North Dakota towns list about as much on the Register as the country (a typical North Dakota town has 2.8 per 10,000 residents, the U.S. 2.4), so Thompson’s 0.0 sits below most of its state (22% of North Dakota towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C+. The pre-1940 share is a Census survey estimate (±4.6 points). The founding year is the first post office, not a stated founding date.

What stands out about Thompson’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The first residents of the town were businessmen who had come to support the needs of new settlers to the area. The town was first called Norton because the first buildings of the town were adjacent to land owned by George Norton. However, when the railroad came in 1881, the name caused an issue, since there was already a nearby town of Norton in Minnesota.
Albert Thompson, co-owner of a general store with his brother Robert, was commissioned postmaster in January 1881. The name of the town was then changed to Thompson in honor of Albert Thompson.
Nothing in the archives for these yearsWeddings on Main Street, storms, parades, school pictures, the old store. If it’s in your family album, it belongs here.
The Thompson post office opened in 1881, the earliest record of the town by name (U.S. post office records).
