California is the most populated state in the U.S with 38 million people and is bigger than the UK by quite a bit.
Followed by Texas with 26 mill, then New York with 19 mill.
So we're far more crammed in here
Don't get me wrong, I'm not arguing that we are not densely populated compared to America just that that is an interest choice bearing in mind their population has increased four fold during the last century and ours hasn't even doubled!
