HumansD.C. as science mecca
Not only is the D.C. area a center of research policy, but many scientific societies also call this place home. Still, I was a bit surprised to find out that fully one in 10 of our area residents work in research-related fields. That’s 50 percent more than in the next biggest hive of research: the New York City metro area.
