From the Knights website:
What countries have Knights of Columbus councils?
A majority of the members of the Knights of Columbus live in the United States, but there are more than 200,000 Knights in both Canada and the Philippines, and smaller numbers in Mexico, the Dominican Republic, Puerto Rico, Panama, the Virgin Islands, Cuba, Guatemala, Guam, Saipan and the Bahamas. The newest K of C jurisdiction is in Poland, where there are now nearly 2,000 Knights.
I think the writer of this piece just hadn’t thought it through!
