近年来,老年人的现状颇为引人关注,由于子女不在身边或者子女工作忙,导致老人感到孤独。作为子女,孝敬老人是好事。但孝敬老人不光是要接到城里来,还要抽出点时间来多陪陪他们。
人口老化:population aging
人口老化是指某地某时期内总人口中老年人口比例增加的动态过程。根据联合国世界卫生组织定义,65岁以上老年人口占总人口的比例达百分之七时,称为高龄化社会达到百分之十四时称为高龄社会如果老年人口比例达到百分之二十时,则称为超高龄社会。人口老化多见于发达国家,特别是欧洲国家。由于计划生育的影响,中国已于1999年进入了老龄化社会,在2004年底65岁以上人口占总人口比例为7.6%。
Among the countries currently classified by the United Nations as more developed , the overall median age rose from 29.0 in 1950 to 37.3 in 2000, and is forecast to rise to 45.5 by 2050. The corresponding figures for the world as a whole are 23.9 in 1950, 26.8 in 2000, and 37.8 in 2050. In Japan, one of the fastest ageing countries in the world, in 1950 there were 9.3 people under 20 for every person over 65. By 2025 this ratio is forecast to be 0.59 people under 20 for every person older than 65.
人口老龄化问题已经成为了全球性的问题,联合国对此进行了一系列调查。
