Not to rain on your parade here, but..
Rural vs Urban means vastly different things depending on the country we're talking about.
Every country has another infrastructure. That of the USA is extremely different to any European country. It comes with the sheer size of the country already.
Some random US state with the size of your own country but with less than 2 million people population (metaphorically speaking) is a whole other rural by default already
.
Just a little example, from Seattle on the west coast to Fort Lauderdale on the east coast it's a whooping 4400.
So by nature it feels more empty already everywhere, except for the metros.
I lived in rural Germany, and Americans would rather call that suburbs.
I lived in rural USA, and Germans would call that the middle of nowhere.
In both cases it's been 3000 ppl towns.
