Life expectancy has improved steadily and substantially in most high-income countries over the last century. In recent decades, however, the United States, Denmark, and the Netherlands have seen gains in life expectancy stagnate. U.S. life expectancy has been rising at a slower pace than other high-income countries over the last 25 years, particularly for women. Denmark experienced virtually no growth in life expectancy from 1980 to 1995. The Netherlands experienced stagnation in the rate of growth in life expectancy starting in the early 1980s and continuing until 2002. While increases in life expectancy in Denmark and the Netherlands have resumed, the growth rate of U.S. life expectancy remains exceptionally slow.
Troubled by the widening gap between life expectancy in the United States and many other industrialized countries, the Division on Behavioral and Social Sciences and Education at the National Institute on Aging supported a National Research Council (NRC) expert panel to investigate the causes of stagnation in U.S. life expectancy at age 50 and above. The goal is to understand the factors contributing to stagnating life expectancy gains and identify ways to improve health in order to narrow the gap between the United States and countries with improving life expectancy. This newsletter discusses life expectancy trends in the United States, Denmark, and the Netherlands, highlighting some of the key findings from the resulting publications.
