Over the sound of a country crooner(低吟歌手) praising Jose Cuervo tequila, Julie Kaufmann encourages her class of line dancers with some pointed advice(明确的建议). “This will help those neurons fire(神经元放电) and prevent cognitive decline(认知衰退),” she says, explaining that following steps in sequence will keep their memory sharp. For those with knee, hip or balance issues she offers an alternative to the grapevine(葡萄藤步), a move where dancers cross one foot in front of the other. “You are ageing gracefully(优雅老去)!” she calls out to the room, filled with giddy(头晕目眩的、兴奋的) older adults spinning around in orthotic sneakers(矫形运动鞋).
在乡村歌手赞美何塞·库尔沃龙舌兰酒的音乐背景下，朱莉·考夫曼正在向她的排舞班传授一些明确的建议。“这将有助于神经元放电，预防认知衰退，”她解释道，按顺序跟上舞步能保持记忆敏锐。对于有膝盖、髋部或平衡问题的人，她提供了葡萄藤步的替代动作——一种舞者将一只脚交叉到另一只脚前的步伐。“你们正在优雅地老去！”她对着满屋子穿着矫形运动鞋、欢快旋转的老年人喊道。
In Winchester, Massachusetts, a suburb of Boston, stately(庄严的、气派的) colonial homes sit on manicured lawns. The public schools are among the most sought-after(最抢手的、最受欢迎的) in the state, which boasts(拥有（引以为豪的）) America’s highest-scoring public education system. But one of the most popular institutions in town is the Jenks Centre, the town’s senior community centre where Ms Kaufmann’s line dancers gather. So many older residents now attend events at the centre that it has had to expand its private transport service(私人交通服务) and the car park can no longer accommodate the steady stream of patrons(源源不断的常客).
在马萨诸塞州温彻斯特——波士顿的一个郊区——庄严的殖民风格住宅坐落在修剪整齐的草坪上。这里的公立学校是该州最抢手的，而该州拥有美国评分最高的公共教育体系。但镇上最受欢迎的机构之一是詹克斯中心，即镇上的老年社区中心，考夫曼女士的排舞者在此聚集。现在参加中心活动的老年居民如此之多，以至于中心不得不扩大其私人交通服务，而停车场已无法容纳源源不断的常客。
Though the ageing of rural America is a familiar story, in the past few years the same pattern has crept(悄然蔓延) across suburbia(郊区（总称）). Suburbs were built for young and growing families and often anchored around(以……为核心) a public-school system; but between 2000 and 2024 the number of elderly residents living in suburban counties more than doubled(增加一倍多). Meanwhile, the number of young children barely budge(移动、改变)d and in many places even fell. That has consequences for housing markets, schools and local politics.
尽管美国农村的老龄化已是老生常谈，但过去几年里，同样的模式也悄然蔓延到了郊区。郊区是为年轻和成长中的家庭建造的，通常以公立学校系统为核心；但在2000年至2024年间，居住在郊县的老年居民数量增加了一倍多。与此同时，幼儿数量几乎未变，许多地方甚至下降了。这对住房市场、学校和地方政治产生了影响。
