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 Shell Valley’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 two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±2.5 points) is firm at this size.
