The Wall Street Journal has put together a great interactive infographic on the age of our congressmen and senators. They are really old. The average age right now is around 63 in the Senate and 57 in the House. It's the oldest Congress has ever been. The youngest was in 1981, and even then it was about 53 and 49, respectively. Perhaps most curious, elected Democrats tend to be older than Republicans, even though old people are more often Republicans. Play around with the full graphic here.
