Some global NGO movements have remained decentralized. The YMCA, is, arguably, the oldest global NGO movement. Founded in London in 1844, it opened locations in Boston and Montreal in 1851. There are now YMCAs in 124 countries. However, the central association, based in Chicago, reports no shared results and works with a budget of <$1m. The YMCA undertakes few, if any global programs or advocacy.
