Boston

NoteWhile the source URL contains 'boston' in its path (idealist.org/en/nonprofit/...the-future-society-boston), the actual text excerpt provided does not explicitly state that Boston, MA is the headquarters. The text only mentions the organization is 'based in the United States and Europe' without specifying a particular city or headquarters location. The additional context about staff in 12 countries is not addressed in the excerpt either. To confirm the claim, the source would need to explicitly state 'headquarters in Boston, MA' or similar language.

NoteThe source text explicitly states 'The Future Society Boston, MA' as the organization's location and confirms it is a nonprofit. The claim that headquarters are in Boston, MA is directly confirmed by the source. The additional context about staff in 12 countries across US and Europe is not contradicted by the source, though it is not explicitly verified in the provided excerpt.
