Donors in Alexandria, the District and Arlington ranked just behind Seattlites in the ranking by Blackbaud, a technology provider for nonprofit organizations. The ranking looked at 265 large cities, with a total population of more than 100,000.

Alexandria donors contributed $4.7 million online, which amounts to an average of about $33 per person, the analysis found. In D.C., more than $14 million, or close to $24 per person, were donated online. Arlingtonians’ online donations totalled nearly $5 million, more than $23 per person. (Seattle donors contributed roughly $23 million, or $38 per person.)

On the other end of the spectrum, cities whose residents contributed the least online donated less than a dollar per capita. These cities include Detroit, Mich.; Newark, N.J.; Miami Gardens, Fla.; and Brownsville, Tex.

Blackbaud found that donors nationwide contributed more than $509 million in online donations in 2012 — a 15 percent jump from the previous year. Comparatively, overall giving grew less than 2 percent from 2011 to 2012.
