Lifespans of United States Presidents

By popular request, this is a variation of a previous visualization I did. Below is a visualization of the lifespan of every US president. In 1822, every single one of the first 19 US presidents was alive except for George Washington. Since then we've had a few other periods of 18 past, present, or future presidents being alive, though never more than that. Some more fun facts:

  • Eight future US presidents were alive during the signing of the Declaration of Independence in 1776
  • Martin van Buren was alive during the US Revolutionary War. Woodrow Wilson was president during World War I. Their lives overlapped during the US Civil War.
  • Ronald Reagan and Theodore Roosevelt both lived during World War I
