Demographics of Aging
ОглавлениеAs of this writing, Monaco leads the world in life expectancy at-birth, standing at 89.57 years. Macau follows at 84.48 years, then Japan at 84.46 years, Singapore at 84.38 years, and San Marino rounds out the top-five at 83.18 years.1
A number of nations report sharply rising life expectancy data:
•The United States Centers for Disease Control & Prevention (CDC) reports2 that the average life expectancy in the US rose to 78.8 years in 2012. The age-adjusted death rate for Americans decreased 1.1%, as seniors’ life expectancy rose to stand at an additional 19.3 years. Women age 65 and older in 2012 can expect to live another 20.5 years, while men may get around an additional 18 years. The CDC Data Brief attributes the increased life expectancy to an overall greater awareness and implementation of healthy lifestyles.
•The United Kingdom’s Office for National Statistics reports3 that as many as two-thirds of the babies born in the UK in 2012 will celebrate their100th birthday. And by 2037, most British children will routinely live until nearly 100 years of age.
•The lifespan for Swedish women4 has risen 15 minutes each hour since 1840. While a Swedish female born in 1840 lived to be just 45 years, a girl born in 2013 will live to an average of 84 years – a gain of 40 years in six generations.
Researchers from the Max Planck Institute for Demographic Research (Germany) report5 that: “Life expectancy is increasing in most countries and has exceeded 80 in several, as low-mortality nations continue to make progress in averting deaths.” Observing a sharp decline in early mortality in the past four generations that points to “the bulk of this mortality reduction has occurred since 1900,” the study authors cite improvements in clean water, shelter, food, and medicine as primary factors in the life expectancy gains. The study authors note that: “This observed plasticity in age-specific risk of death is at odds with conventional theories of aging.”
