Sporting news site The Roar crunched World Rugby statistics on the number of club rugby players in a nation relative to its total population.
Samoa has some 12,000 registered rugby players, meaning that 1-in-17 members of the population are involved with the sport, the site found.
We rank behind Tonga (where fewer than 1-in-5 people are players); Niue (1-in-7); Fiji (1-in-7.5); and the Cook Islands (1-in-9).
The Samoa Rugby Union CEO, Faleomavaega Vincent Fepulea'i, said the ranking shows that Samoa is a competitive nation in rugby.
