There are various world population counters online that intrigue me. A couple nice ones are below.
- This one from the US Census folks is kind of intriguing in that it shows births and deaths graphically.
- Worldometers is fascinating in all the rolling data they present.
I built an activity around What’s Your Number from Population Action International. Students enter their birthdate to see what their population number is. They enter the birthdates of older and younger relatives (going back a generation or two if they can), graph the data, and fit an exponential curve to it.
