American probability of death over time

By Razib Khan | May 13, 2011 1:52 pm

It’s Friday the 13th. So why not a morbid post? I stumbled onto to some “life tables” for 2007. Actually what the link gives you is the probability of death and life expectancy at a given age for males and females. This is obviously important for purposes of private and public insurance. The tables are naturally broken down by sex because males and females differ in their likelihood of death. Women are well known to have higher life expectancies in all but the most primitive of nations today.

I wanted to do a little visualization. I limited the years across the interval 0 to 100.  Since I find life expectancy a boring statistic (well known) I want to focus on probability of death in a given year. I generated four tables.

– First, a table which shows probability of death in a given year log transformed. I had to transform because the difference between a 1 year old and a 100 year old spans four orders of magnitude.

– Second, a table which illustrates the absolute change in the probability of death year to year. This is basically measuring the absolute change between year X and year X – 1. Concretely an example might be (probability of death at age 10) – (probability of death at age 9)

– Third, a table which takes the result from the above table and standardizes it by the value for the previous year, so it shows the year to year change proportionally. So [(probability of death at age 10) – (probability of death at age 9)]/(probability of death at age 9).

– Finally, a ratio of male to female probability of death over the years. This is usually > 1 obviously. Total surprise to me that it goes < 1 around age ~10. Go team male!

Remember that age is the x-axis on all the charts below.

The raw data is appended below the charts. Have a good weekend!

    I didn’t know about the gender convergence at extreme old age. Interesting.

  • Doug Henning

    @Brian
    This may come as a shock, but eventually the probability of death for both men AND women is exactly the same: 100%.

  • Chris T

    I’m surprised to see that a significant fraction of the life expectancy difference between men/women is actually from higher death rates among 14-35 year olds in males.

  • John Emerson

    My over / under is 2027. My genetics would make me older than the norm, but my lifestyle probably cancels that.

  • simplicio

    Yea, I’m kinda curious. Why do males have such a higher death probability at 15-35 (3x !). Are we more prone to a particular disease (heart disease maybe?)?, higher suicide rates?, more likely to die in violence?

  • Åse

    My first thought was that the boys become slightly more prone to take risks than girls. I thought there was a suicide difference also. And wars.

  • Sandgroper

    In the American data, as in most countries, wars are trivial as a cause of death.

    Think traffic, violence, drug use, suicide…

    Young men are the big risk takers.

  • Jon claerbout

    I’d rather see the quartiles. In science we give the mean and variance of our estimates.
