The troubled economy is causing more older donors to cut back their giving this fall, while younger people plan to step up their giving, finds a new study by the Grizzard Communications Group, a direct-marketing firm that works with nonprofit organizations. The results of the study were distributed on Business Wire.

The company said its study found that donors ages 25 to 34 are more likely to increase their giving to charitable organizations this fall while those over the age of 65 were more likely to say they will give less.

Of all respondents, 44 percent say they will contribute the same amount to charity compared to what they gave last fall. Almost 30 percent of all respondents say they plan to give less to charitable efforts, and about a quarter say they plan to stop giving altogether.
