In this study, we analyze whether there are differences in attitudes towards nonprofit organizations (NPOs) between the generational cohorts of Baby Boomers, Generation X, and Millennials. We do so by analyzing survey data from Switzerland in two steps, a Bayesian estimation as well as a cluster analysis. The overall results suggest that there are, at best, only few and small intergenerational differences: The only consistent effect we find are the more negative attitudes of the Baby Boomer cohort towards professional associations and towards sports NPOs, but those differences could be due to life cycle rather than intergenerational effects. Overall, our results suggest that the Millennial generational cohort is at least as interested in and willing to engage with NPOs as previous generational cohorts. *
