The following map details the United States based on how many people, on average, are covered by a given state’s area code:

The key’s a bit hard to read, so here’s a typed-out version:

Darkest green: More than 1.25 million people per area code

Second darkest green: 1-1.25 million people per area code

Third darkest green: 0.75-1 million people per area code

Lightest green: 0.5-0.75 million people per area code

Essentially, darker states have, in general, more people covered by a given area code. Lighter states have, in general, fewer people covered by a given area code.

(To those of you in darker-colored states – you might start seeing another area code by the end of the next decade).
