[00:03.25]Unit 24 Society Language Awareness 9 [00:09.27]Are Societies Ageing Too Fast? [00:13.10]An ageing society is one [00:15.03]in which the population of people [00:16.83]over the age of 60 is increasing. [00:19.73]The global population at present [00:21.58]is about 6 billion with 1 person in every 10 [00:25.38]aged 60 or above. [00:27.50]The United Nations projects that by 2050, [00:30.88]it will be 1 in every 5. [00:33.37]This will mean that for the first time [00:35.36]in human history the population of older [00:38.23]persons will be larger than the population [00:40.42]of children! [00:41.64]What are the causes of this population change? [00:45.01]One reason is that dramatic health advances [00:47.80]have added 20 years [00:49.57]to the average life-expectancy, [00:51.92]and another is that birthrates [00:53.71]have dropped as people, [00:55.69]especially women, are educated. [00:58.43]Measures to slow population growth [01:00.54]like China's one-child policy, [01:02.89]have also contributed to lowered birthrates. [01:06.13]The increase in the aged population [01:08.77]is not just an interesting trend however; [01:12.02]it also has severe implications [01:14.33]for the future of global economies. [01:17.60]People traditionally retire at 65 [01:20.61]and live on government pensions. [01:22.99]As people grow older, [01:24.21]a huge financial burden will be placed [01:26.61]on the government.
