Baby boomers, who were born between 1946 and 1964, may make up a lion’s share of the U.S.’ charitable donors. Though people born before 1946 — the Silent and Greatest generation — gave the most money to charity each year.

According to a study conducted by Blackbaud, a technology consulting firm that works with nonprofits, 51 million boomers said they gave money to charity in 2013. They made up 43 percent of the country’s total charitable donors and had an average annual gift of $1,212.

Almost half as many members of the Silent and Greatest generations said they gave money to charity this year, according to the study. But these 27.1 million donors gave an average gift of $1,367 a year.

The study also found 32.8 million members of Generation Y, people born between 1981 and 1995, and 39.5 million members of Generation X, people born between 1965 and 1980, gave to charity last year. The average member of Generation Y gives $481 a year while the average member of Generation X gave $732 a year.
