Kurdish part is really exeggerated. Azeris are close to 30% not 20%.
Why are Qazvin not listed as Azeri settlement? It is nearly 100% Azeri. Same with Karaj, and of course, Hamadan.
As you can see, there are Azeri settlements even in south of Iran.

the Azeri language is a Turkic language that I respect it much but what the hell are Qajar languages? I've never heard about such languages in any linguistics book. even if there was a Qajar language that I think no Iranian has ever heard about it, but it is better for us that those languages have ceased to exist. the Qajars sold Iran to Britain and Russia and any other foreign countries and I don't blame the British or the Russians for that at all. the Qajars didn't deserve to rule over Iran, It's just as simple as that.
Qajar are one of the Azeri tribes, like you can see in that map. Qajar are listed as a Azeri dialect.
