Sharp drop in U.S. death rate surprises experts

Milder flu season
Also, the flu season for 2004 was milder than 2003, which helped explain the more than 7 percent drop in the influenza death rate, Minino noted.

The death rates for 11 of the 13 other leading causes of death also declined, with only Alzheimer’s disease (the No. 7 killer) and high blood pressure and kidney disease related to high blood pressure (No. 13) inching up.

Even officials at the National Center for Health Statistics were “really kind of concerned” when they first saw their own numbers, said Bob Anderson, the agency’s chief of mortality statistics. But the fact that decreases in the death rate were found nationwide gives them confidence that the findings are legitimate, and not the result of something like changes in data collection.

The government also reported that a baby born in 2004 could expect to live to nearly 78 — an increase of almost half a year from 2003. Women now have a life expectancy of 80.4, up from 80.1. Male life expectancy is 75.2, up from 74.8.

The life expectancy for whites — 78.3 — was up only slightly from the previous year. The increase for blacks was larger, with a rise from 72.7 to 73.3.

The government also reported that the infant mortality rate has dropped to 6.76 deaths per 1,000 births, down from 6.85 the year before. But a huge racial disparity persists. The rate for whites was 5.65 per 1,000 births, for blacks, 13.65.

Japan, Monaco and San Marino had the highest life expectancy, 82 years, in 2004, according to World Health Organization statistics. Australia, Iceland, Italy, Sweden and Switzerland have a life expectancy of 81. Canada, France, Israel, Norway, Spain and Britain are among the other countries with life expectancies above 78.
