Question: What was the combined populations of Iran and Iraq the year that Pakistan national team gained their first international experience?

PFF received recognition from FIFA in early 1948.. The annual National Championship was organized shortly after.

Pakistan's participation in international competitions has not been regular. The standard achieved in the early 1950s could not be maintained because of lack of organization of the game.
