English: Member countries, color-coded by continental confederation, of the World Pool-Billiard Association (WPA), updated as of November 2011. Where sources differ, it has been considered more likely that the relevant continental organization has included or excluded a country (based on new information, such as a national group newly joining that confederation), than the world source being correct based on information somehow more current than the "ground truth" being reported by its own constituent confederations. I.e., the WPA itself is unlikely to have the freshest data.
