January 19, 2011; Source: Convio | Alexandria, Va., Cambridge, Mass. and Arlington, Va., for the second year in a row have topped the list as the nation’s most generous large cities based on online giving in 2010, according to Convio, a provider of Internet marketing and business management applications for nonprofits.

The report ranks the 273 cities with total population of more than 100,000 based on per capita online giving and total amount donated online through Convio online fundraising tools. The current rankings come from donations processed between Jan. 1 and Dec. 31, 2010.

The average gift size increased from $62 in 2009 to $65 in 2010 as more than $389 million was donated in the 273 major cities included in the report. Donors in the most generous cities increased their total online contributions by more than 27 percent over 2009 totals, according to Convio.

The increase in giving is due to more people spending more time online, said Gene Austin, chief executive officer for Convio. “Donors, volunteers, advocates and other constituents of all generations are using the Internet, social, mobile and digital technologies in their daily lives. That is reflected in the dramatic increase in the amount of dollars raised online.”

Other cities in the top 10 include: Seattle, Washington, Berkeley, Calif., St. Louis, San Francisco, Ann Arbor, Mich. and Minneapolis. To see the complete list click here. –Aaron Lester
