How is the Robert Wood Johnson Foundation funded?

The Robert Wood Johnson Foundation (RWJF) is primarily funded through its endowment, which was established by the estate of Robert Wood Johnson II, co-founder of Johnson & Johnson. This endowment generates income through investments in various asset classes, allowing the foundation to finance its health initiatives and community programs. The foundation does not accept donations or grants from outside entities, relying instead on the returns from its investments to support its mission of improving health and healthcare in the United States.
