National Journal’s Peter Bell answers important beltway questions:

Hill People: Who Are They and Where Did They Come From?

Fun facts from the infographics:

• Republican staffers tend to live in Virgina. And most Democratic staffers live in D.C.
• Georgetown University has the most alumni working in senior positions on Capitol Hill.
• Almost 60% of Congressional senior staff have Graduate degrees.

NOTE: This graphic is part of National Journal’s special Hill People issue. Every four years, National Journal devotes an entire magazine to profiling top congressional staffers, many of whom toil behind the scenes in relative anonymity.
