Minnesota nonprofits lost an estimated $1 billion in revenue in April because the COVID-19 pandemic forced the cancellation of fundraising events and reductions or closures of other revenue-generating programs.

The Minnesota Council of Nonprofits has released the results of a survey of the state's nonprofits, part of a national survey conducted in partnership with the Federal Reserve Bank on how the coronavirus outbreak and economic downturn are affecting the sector.

Arts and health nonprofits took the biggest hits, but the entire sector is facing a financial crisis, with nearly all nonprofits facing some level of disruption.

"It's going to be substantial impact for an unknown period of time," said Jon Pratt, executive director of the statewide council. "We're going to have to do things differently because the needs will have shifted dramatically, but also the resource base."
