Approximately how many individuals were members of scouting organizations worldwide in 2011?

The correct answer is based on the data indicating that in 2011, the estimated number of individuals who were members of scouting organizations worldwide was approximately 41 million. This figure encompasses various youth and adult members involved in scouting, which includes Boy Scouts, Girl Scouts, and similar organizations across the globe. This membership signifies the widespread reach and impact of scouting in promoting youth development, leadership skills, and community involvement.

In contrast, other figures may represent different years or instances; for example, 25 million may underestimate the global reach of scouting, while 55 million and 70 million may overestimate it, not aligning with official statistics from that period. Therefore, the choice of 41 million accurately reflects the recognized membership count in scouting organizations worldwide in 2011.
