I also thought that the town was just a small part of the voting area, but then I looked at wikipedia.
https://en.wikipedia.org/wiki/Columbia,_New_Hampshire
The town’s area is 61 square miles. The term ‘town’ might mean something different than it does in Ohio.
“At the 2000 census there were 750 people, 300 households, and 218 families living in the town. The population density was 12.3 people per square mile (4.8/km2). There were 449 housing units at an average density of 7.4 per square mile (2.8/km2). “
750/61 = 12.3 like Wikipedia claims.
“The age distribution was 24.8% under the age of 18”
750 - 750(.248) = 564 potential voters
Please check my math and other claims. It is 0530 and I have not had my hot chocolate yet.
I looked at Google maps and imagery. First, this square mile thing is misleading. At the far NW corner of the urban area is what you and I would call civilization (bars, restaurants, homes). The other 90-percent of the city limits is wooded areas, cabins, and hunting accommodations. I can only assume they incorporated this rural area in....to pay for city water and police/fire protection.
Second, when you view for pubs/eating establishments....a heck of a lot for a population of 700 to 800 people. If I tried to compare the area to Tenn/Ala....with that many establishments, local population would have to be in the 2,000 range.
