Sharing birthdays

As of the 23rd May 2022 this website is archived and will receive no further updates.

understandinguncertainty.org was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Many of the animations were produced using Flash and will no longer work.

My wife and I had a daughter on the 13th August which coincidentally is the same as my mothers birthday. One year later my brother also had a baby (this time a boy) on the 13th August. Neither baby were due on this date. My daughter was late and my nephew early. As well as my daughter sharing my mothers birthday, she was also given the same name as a baby girl my mother lost 20 years previous during pregnancy, the name of which she had never disclosed.
