See the up-to-the-minute story of our changing population on the Equitable Demograph at the World's Fair. Every 71/2 seconds a baby is born in the U.S.A. Every 17 seconds someone dies in the U.S.A. Every 12 seconds our population increases by one. See it for yourself: the whole, fascinating story of our changing population -- on the Demograph at the Equitable Pavilion. A gigantic mechanical marvel, the Demograph shows, minute by minute, how each of our states contributes to the dramatic cycle of births and deaths. It also portrays many other interesting aspects of the U.S. population. See the Equitable Demograph. You'll find it on The Pool of Industry, with its Fountain of the Planets.
