Last month, Achieve, a research and marketing agency for causes, released The Millennial Impact Report Retrospective: Five Years of Trends. The study provides insight into millennials’ attitudes towards cause-engagement, volunteering, and donations.

It also includes overviews of the platforms and channels that millennials use for interactions with organizations.

The study’s 2016 post-election survey of millennials found that 78 percent of millennial survey respondents reported voting in the presidential election and that their top three issues were employment/wages (32 percent), the economy (29 percent) and—significantly—healthcare (27 percent). The retrospective and the upcoming 2016 research are a useful guide for developing millennial outreach strategies.
