    [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.

    [01:26.61]
