Conception Coincidence

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.

Myself and my partner have two children, now aged 4 and 6. In a Civil Partnership, we each carried one of the girls who were conceived using IUI and donor sperm. Given the medicalisation of the start to our family, we know the exact day each child was conceived - the oldest on September 21st 2004, the youngest on November 20th 2006. The first coincidence comes with the fact that my partner conceived our eldest on her best friend Charlotte's birthday. The next coincidence comes with the fact that I conceived our youngest on my best friend Rosie's birthday. The biggest coincidence of all comes with the fact that we each conceived at exactly the same age: 31 years, 3 months and 13 days!
