February 14, 2011; Source: beliefnet.com | The study referenced in this blog post on beliefnet.com reinforces the fact that donors are definitely not a zero sum game. A study conducted by Grey Matter Research Consulting suggests that 50 percent of those that give to their houses of worship also give to other causes. Additionally, the more the donor gives to his or her church, the more he or she will give elsewhere. The study, based on a telephone and online survey of 2,005 people, found that “donors who gave less than $100 to a house of worship also donated an average of $208 to other charities. Those who gave between $100 and $499 to a congregation gave an average of $376 to others. Donors of between $500 and $999 to places of worship gave an average of $916 to others.”—Ruth McCambridge
