Approximately 97% of the United States' land area is within rural counties, and 60 million people (roughly 19.3% of the population) reside in these areas. source

Urban areas make up only 3 percent of the entire land area of the country but are home to more than 80 percent of the population. Conversely, 97 percent of the country's land mass is rural but only 19.3 percent of the population lives there.source

This actually surprised me too! :)

Have a great day!
