This map comes with "DLC", which are optional regions you can add for a few select countries. It's hard to make a good Real Traveler's Map without having some regions be too small or too large, or sometimes the official divisions are not perfect for a traveler for whatever reason. Up to you if you want to change one or more countries. Feel free to add or suggest others if you want.

What counts as having visited or lived in a subdivision? Completely up to you, use your own definition. If you need official guidance however, I personally like this Anon's post:

In short, any visit of any length counts as a visit as long as you made a conscious effort to go there for touristic reasons. This excludes layovers and transits and such, but includes short visits such as leaving the airport for a few hours during a layover. For living, more than a month for non-touristic reasons, meaning you could travel around while there, but the reason you went was work or study or such.
