I’ve been playing with the statistics feature of the software I use for my family tree, and it comes up with some fascinating stuff.
For my Strachan tree, the average age of death is 47. Hardly anyone died at that age, though: the average age is low because so many died within the first three years of life. In fact, around 13.5% of the deaths happened before the age of 3 and 20% had died by the time they were 10 years old.
At the other end of the scale, 3.5% of them made it into their 90s, 9.2% signed off in their 80s, and 15% popped their clogs during their 70s. That makes 27.7% reaching what we could call old age.
My Strachan tree dates back to the 1700s with most of the people on it living during the 1800s. Given that nearly all the men were coal miners and many of the women gave birth to an awful lot of children, and considering the crowded and unsanitary conditions in which they must have lived, my Strachans appear to have been a pretty tough lot.
