Unexpectedly Intriguing!
13 September 2007

Yesterday, Reuters reported that the U.S. Centers for Disease Control had projected that U.S. children born in 2005 are expected to live for 77.9 years, continuing a decades-long trend of increasing life expectancy from birth in the U.S. We thought we'd take a moment to show how U.S. life expectancy from birth has changed from 1950 through 2005:

U.S. Life Expectancy from Birth, 1950-2005

Reuters goes on to say that the death rates from the top three natural causes of death in the United States, heart disease, cancer and stroke, all decreased in 2005 compared to the previous year, helping to contribute to the increase in U.S. life expectancy. What the Reuters article doesn't tell us is something we find more interesting. Here, what they don't tell us is that the CDC's life expectancy figures also incorporate non-natural causes of death, such as those resulting from fatal injuries, which include motor vehicle accidents, falls, accidental poisonings, homicides, et cetera.

This is important because these factors represent the leading causes of premature death in the United States for all ages up through 44 years old. Premature deaths caused by these non-natural factors result in a lower life expectancy figure for the U.S., which gives a somewhat misleading picture of the general health of U.S. individuals.

What makes this relevant is that the Reuters article also had this to say:

The United States, a country of 300 million people, ranks 42nd in the world in life expectancy, according to previously released data.

This low ranking in life expectancy is often pointed to as being the result of the deficiencies of the health care system in the U.S. The problem with this thinking however is that it does not account for the fact that the U.S. has a disproportionate number of individuals who die as the result of fatal injuries compared to the other wealthy nations of the world. This does not reflect upon the quality of health care in the U.S., in that these events almost universally occur independently of the condition of health of the individuals who die as a result of these factors.

Two University of Iowa researchers, Robert L. Ohsfeldt and John E. Schneider, reviewed the data for the nations of the OECD to statistically account for the incidence of fatal injuries for the member countries. The dynamic table below presents their findings, showing both the average life expectancy from birth over the years 1980 to 1999 without any adjustment (the actual "raw" mean), and again after accounting for the effects of premature death resulting from a non-health-related fatal injury (the standardized mean). You may sort the data in the dynamic table from low to high value by clicking on the column headings, or from high to low value by clicking a second time.

Table 1-5: Mean Life Expectancy at Birth, OECD Countries, Actual and Standardized by OECD Mean Fatal Injury Rates, 1980-99
OECD Nation Actual (Raw) Mean (Does Not Account for Fatal Injuries) Standardized Mean (Accounts for Fatal Injuries)
Australia 76.8 76.0
Austria 75.3 76.0
Belgium 75.7 76.0
Canada 77.3 76.2
Denmark 75.1 76.1
France 76.6 76.0
Germany 75.4 76.1
Iceland 78.0 76.1
Italy 76.6 75.8
Japan 78.7 76.0
Netherlands 77.0 75.9
Norway 77.0 76.3
Sweden 77.7 76.1
Switzerland 77.6 76.6
United Kingdom 75.6 75.7
United States 75.3 76.9

If you've sorted the data in the dynamic table, you find that without accounting for the incidence of fatal injuries, the United States ties for 14th of the 16 nations listed. But once fatal injuries are taken into account, U.S. "natural" life expectancy from birth ranks first among the richest nations of the world.
