Boomers are generous. They give in different ways, ranging from volunteering in their local community to donating cash, and their giving adds up. Boomers are responsible for 70 percent of all charitable giving in the United States. Baby boomers’ giving comes through many different ways, whether it’s at the grocery store checkout to Facebook prompts to Internet campaigns. The number of Boomers who say they have given online has increased from 48% in 2010 to 57% in 2012, showing that they aren’t just opening up their calendars or checkbooks — they’re also opening up their computers.
