We calculated population-level estimates of mortality, functional health, and active life expectancy for black and white adults living in a diverse set of 23 local areas in 1990, and nationwide. At age 16, life expectancy and active life expectancy vary across the local populations by as much as 28 and 25 years respectively. The relationship between population infirmity and longevity also varies. Rural residents outlive urban residents, but their additional years are primarily inactive. Among urban residents, those in more affluent areas outlive those in high-poverty areas. For both whites and blacks, these gains represent increases in active years. For whites alone they also reflect reductions in years spent in poor health.
我们计算了1990年居住在23个不同地区以及全国范围内的黑人和白人成年人在人口层面的死亡率、功能健康和健康预期寿命估计值。16岁时,不同地区人群的预期寿命和健康预期寿命分别相差多达28年和25年。人口虚弱与长寿之间的关系也各不相同。农村居民比城市居民寿命长,但多出来的这些年主要是无活动能力的。在城市居民中,较富裕地区的居民比高贫困地区的居民寿命长。对白人和黑人来说,这些增加都意味着活动年限的增加。仅对白人群体而言,这也反映了健康状况不佳的年限减少。
