Question

What was the population density of most of the land in nevada wyoming arizona and oklahoma in 1890?

Answer 1

Census.gov reported population density for Arizona in 2007 at 57 people/square mile, Wyoming at 51.3.. Other records show 0-2 people/square mile including Nevada and Oklahoma. With that very minimal rates as reference, we can conclude that there is zero population density in those 4 cities in 1890.
