[00:03.25]Unit 24 Society Language Awareness 1 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 2 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]
