Charity is big business, and Scott Jackson helms one of the biggest. Global Impact, based in Washington, D.C., fundraises for international humanitarian causes and has raised $1.8 billion since it was founded in 1956. As president and chief executive officer, Jackson oversees the marketing effort behind the Combined Federal Campaign, the largest employee giving campaign in the U.S. Previously at World Vision International and PATH, Jackson was a founding member of the ONE Campaign to end global poverty.

Devex spoke with Jackson about giving trends and his new memoir, Take Me With You: One Person’s Journey to Find the Charity Within, following his keynote address at this week’s Global Washington conference in Seattle.

Q: What has been the impact of Giving Tuesday on the charitable sector, and does this one-day approach compete with sustained giving over the course of the year?

A: Giving Tuesday is an additive rather than a substitution. So far, the numbers show that Giving Tuesday is helping. We're entering into a third year in a row of record giving since we've gotten past the recession, and yet we don't have significant economic growth. Giving Tuesday and anything that shines the light on the need to continue to give is helpful.

Q: Where are federal employees choosing to donate their dollars?

We're seeing a lot of issue-based fundraising, key issues such as homelessness, education, health. Often, federal employees contribute to charities like St. Jude Children’s Research Hospital that are supporting their own families, veterans, and communities. That's one trend. The other is continued interest in international causes. The Combined Federal Campaign has always had a real interest in international giving ... [but] There is a trend in these times towards domestic giving. As we have the world here at home, we have the world's problems. As we face those problems ourselves, especially with disasters, people want to make sure they're taking care of their families and their communities.
