We’ve charted the business community’s nonprofit support for the past four years, and this year we find support for board membership and earmarking profits for charities have decreased over the past year.

Overall support is holding steady. Responses were provided by 552 Oregon Business readers in an online survey conducted in late August by research partner CFM Strategic Communications.
