Dynamics of American Giving: Descriptive Evidence

Almost all of the scientific literature on charitable giving is implicitly based on a static paradigm which posits there are non-donors who never give and donors who habitually give year-in/year-out to a specific charitable purpose. This article presents evidence that charitable giving is not static, but dynamic: Few Americans never give, and among Americans that donate the majority are switchers—giving in some years but not others or switching from one charitable purpose to another. The implications are that a static perspective is misleading, and research questions should place more emphasis on the time dimension of charitable giving.
