When it comes to charitable giving, Somerville lags behind Cambridge, Boston and the United States as a whole, according to data released by The Chronicle of Philanthropy.
The data comes from 2008 tax returns, and The Chronicle of Philanthropy used the data to create a map of charitable giving across the entire country.
According to the figures, Somerville residents gave on average 2.9 percent of their discretionary income to charity. The median contribution was $1,267, with the median disposable income listed as $44,003, one of the lowest in the region.
By comparison, Cambridge residents donated about 4.2 percent of their discretionary incomes to charity. (Cambridge had a median charitable contribution of $2,463 with a median discretionary income of $58,141.)
In Boston, the median contribution was $1,915 with a discretionary income of $45,010. Bostonians donated 4.3 percent of their discretionary incomes to charity.
Across the country, Americans gave about 4.7 percent of their incomes to charity, with a median contribution of $2,564 and a median discretionary income of $54,783.
Somerville, however, was a tiny bit more charitable than the state of Massachusetts. Massachusetts residents gave about 2.8 percent of their incomes to charity.
