While the 113th Congress is just over a month old, the dynamic of the worlds most deliberative body is still being shaped. Members are retiring early, leaving congress due to legal trouble, pursuing other interests in the private sector, or joining the President’s administration. However, the majority of the legislature is in place, and Bloomberg Businessweek has a fascinating chart breaking down the professions and trades of everyone in congress.

Perhaps not surprisingly, the overwhelming number of members are lawyers. The House boasts 128 lawyers and the Senate adds another 45. The second largest group represented are businesspeople with 130 members total in both bodies. Maybe somewhat surprising is the smaller number of career politicians as only 55 members of the House and 9 members of Senate have spent their professional lives in politics.

Though congress is still largely a male dominated institution (by a margin of 337), women gained a total of six seats while men lost a total of five. Among the demographic groups with the greatest amount of change were businesspeople with a net loss of 7 seats, the entertainment industry with a net gain of 3 seats, educators with a net gain of 2 seats, and lawyers with a net gain of 2 seats.
