American charities have weathered a significant drop in giving this year, and while they’re hoping for a holiday miracle, a recent survey shows that instead they will probably see a decrease in year-end generosity.

In light of the economic downturn, only 38 percent of Americans say they are more likely to give a charitable gift as a holiday present this year, compared to 49 percent last year, according to a survey by Harris Interactive to be released today.

The nation’s most successful fundraising organizations expect to see their income decline by an average of 9 percent in 2009.
