Scouting is a global movement with over 50 million members worldwide, all part of National Scout Organizations (NSOs). The role of the NSO is to support and develop Scouting in that country, and facilitate contacts with other NSOs and the World Organization. To become a member of WOSM, NSOs must gain recognition from the World Scout Conference. There can only be one NSO per country. In the case of a country having more than one National Scout Association (NSA), a federation is formed for the purpose of national coordination and world membership.
There are currently 169 NSOs in the world. The most recent member, Iraq Scout Association, joined on 17 August 2017. In addition to the 169 member countries, we are aware that local Scouting activities exist in at least another 58 countries and territories worldwide.
Below you can find the membership census as of 31 December 2016. In some countries, the National Scout Organization may be larger than indicated, where girls and women are registered only as members of the World Association of Girl Guides and Girl Scouts (WAGGGS).
