The researchers, David Kindig and Erika Cheng of the University of Wisconsin, looked at federal death data and other information for nearly all 3,141 U.S. counties over 10 years. They calculated mortality rates for women age 75 and younger, sometimes called "premature death rates," because many of those deaths are considered preventable.

Many counties have such small populations that even slight changes in the number of deaths produce dramatic swings in the death rate from year to year. To try to stabilize the numbers, the researchers computed some five-year averages. They also used statistical tricks to account for factors like income and education.

They found that nationwide, the rate of women dying younger than would be expected fell from 324 to 318 per 100,000. But in 1,344 counties, the average premature death rate rose, from 317 to about 333 per 100,000. Deaths rates rose for men in only about 100 counties.

The study wasn't the first to reach those conclusions. Two years ago, a study led by the University of Washington's Dr. Christopher Murray also looked at county-level death rates. It too found that women were dying sooner, especially in the South.
