  1. 100 years ago life expectancy in the United States was 47. Now it’s 78.

    *sigh*

    This is a pet peeve of mine – someone doesn’t understand statistics, and abuses a meaningless statistic to show that they don’t know anything about what they’re talking about.

    Say you have a population of 100 people. 49 of them die before their first birthday. 49 of them die at the age of 90, and two of them die at the age of 45. Average life expectancy of this group is *gasp* 45. Does that mean that most people died when they were 45, and that old people were really rare? No. It means that it’s meaningless to use “average life expectancy” for two periods of time unless they have similar ages of death.

    100 years ago, there was a high infant and child mortality rate. But if you lived past 12 years old, you would likely live into your sixties or seventies. Old people were just as common back then as they are today.
