Scouting is a global movement with over 54 million Scouts worldwide, all part of recognised National Scout Organizations (NSOs) of WOSM (also known as Member Organizations). 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 171 Member Organizations in the world. In addition to the 171 Member Organizations, local Scouting activities exist in at least another 52 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).
