This document discusses which demographic charities should focus on in the future - millennials or baby boomers. It notes that millennials are the largest generation but give the least to charities currently, though they trust brands to do good and individuals over institutions. It argues charities should embrace transparency and new technologies to attract millennials. Meanwhile, baby boomers have more time and money now in retirement, are socially active both online and offline, and will soon lose their core senior audience, so charities should also focus on this demographic. Ultimately, the document concludes demographics divide us but values unite us.
