National progress in life expectancy masks wide local disparities, according to a study published on June 15th and written by researchers at the University of Washington and Imperial College London. Men in Holmes County, Mississippi, for example, have a life expectancy of 65.9 years, the same as men in Pakistan and 15.2 years behind men in Fairfax, Virginia. Gaps between America's counties have widened since the early 1980s. Most alarming, 702 counties, or 30% of those studied, saw a statistically significant decline in life expectancy for women from 2000 to 2007; 251 counties saw a statistically significant decline for men.
国家在预期寿命方面的进步掩盖了广泛存在的局部不公平，根据一项6月15日发表的研究结果，这项成果是由华盛顿大学和伦敦皇家学院执笔。在密西西比的Holmes县的男人的预期寿命是65.9年，跟巴基斯坦男性的预期寿命一样，与佐尼亚州Fairfax男性的预期寿命相比，少了15.2年。美国县城的差距自从20世纪80年代就开始扩大。最值得注意的是，702个县城，或者30%的被研究对象，在2000年到2007年之间，女性预期寿命显著降低，251个县城的男性寿命显著降低。
