Evidence that a charity’s programs are effective is the most important factor in deciding to contribute to that organization, according to a recent survey. Of those polled by The Chronicle of Philanthropy, 68% cited that reason.

Participants pointed to low overhead spending (50%), good ratings from watchdogs (54%) and “working on a cause that has affected me or my loved ones” (39%) as other key influences in their decision to donate.

Most of the respondents (80%) said charities do a “very good” or “somewhat good” job helping people. But, when it came to finances, one-third said charities do a “not too good” or “not at all good” job spending money wisely. And 41% said leaders of charities are paid too much. Only 13% of participants said charities do a “very good” job of spending money wisely.

Princeton Survey Research Associates International conducted the telephone survey of 1,000 adults.
