In 1997 life expectancy for all persons combined rose to a new record high of 76.4 years. Additionally, average future lifetime for newborn girls and boys also established new peaks--79.3 years and 73.4 years, respectively. For girls the 1997 value surpassed the previous high of 79.1 years recorded in 1992 and 1996 while for boys new peaks have been consecutively recorded since 1994. Last year's longevity enhancements among men were larger than those for women--continuing the trend of the past few years. Newborn girls could still anticipate living 5.9 years longer than boys--the gap was 6.0 years in 1996 and 7.0 years in 1989-91. Current projections indicate that the disparity between the genders in average future lifetime may decline to 4.6 years by the year 2050. Also worthy of note is the apparent narrowing of the gap in longevity by race. In 1996 newborn white boys could expect to outlive nonwhite newborn boys by 5.0 years compared with 5.7 years in 1989-91; among girls the disparity diminished from 4.1 years in 1989-91 to 3.6 years in 1996.
1997年，所有人的综合预期寿命升至76.4岁这一创纪录的新高。此外，新生女孩和男孩的平均剩余寿命也创下新高，分别为79.3岁和73.4岁。对于女孩来说，1997年的数值超过了1992年和1996年记录的先前高位79.1岁；而对于男孩来说，自1994年以来连续创下新高。去年男性的寿命增长幅度大于女性，延续了过去几年的趋势。新生女孩预计仍比男孩多活5.9岁，1996年这一差距为6.0岁，1989 - 1991年为7.0岁。目前的预测表明，到2050年，两性在平均剩余寿命上的差距可能降至4.6岁。同样值得注意的是，不同种族在寿命方面的差距明显缩小。1996年，新生白人男孩预计比非白人新生男孩多活5.0岁，而1989 - 1991年为5.7岁；在女孩中，这一差距从1989 - 1991年的4.1岁降至1996年的3.6岁。
