With $2.1 billion in operating expenses, the Woodruff Health Sciences Center (WHSC) has an annual economic impact on metro Atlanta estimated at $4.6 billion. The WHSC is one of the largest employers in the city, and its investment in construction alone, not to mention its biotech start-up companies, is a major source of jobs and boon to the economy. In 2007, for example, the WHSC will open two new facilities, a new medical school building on campus and a four-story joint-venture hospital off campus. And construction planned for the coming decade includes a new research building, a new building for the Rollins School of Public Health, a new facility for Yerkes National Primate Research Center, and new hospital and clinic facilties, including a major expansion of the Emory Crawford Long campus in midtown.
