Areas such as Shanghai have over 520 people per square mile. This is because there is low relief and high precipitation.

Many pensioners are having to continue to work. A solution is to encourage migrant labour.</p><p> Pensions: the Prime Minister has introduced reforms which includes the retirement age being increased from 60 to 65 by 2030 and higher pension contributions from employers, employees and the government.</p><p> Health care: Many pensioners are living in nursing homes or care homes now. This is putting pressure on the health budget, more than half goes towards caring for the elderly.</p><p> In 2006, incentives were introduced to promote independent living at home. A health insurance scheme for over 75s were introduced in 2007. It has been nicknamed the hurry up and die scheme.</p><p> To shorten hospital admissions, a fee a hospital receives after 100 days goes up.</p><p> One care home has hundreds on the waiting list, not enough staff work there for everyone to be admitted.</p></li><li><p>Case study: Ageing population in Japan (continued)</p><p>Advantages</p><p> The greying yen: the elderly saved money. Now, Japanese pensioners are spending; buying luxury goods, travelling and indulging their taste for expensive food. This benefits their economy.</p><p> In the past, their saved money would go to their children to help look after them at an old age.</p><p> Now, children are doing less of the caring.</p><p> Technology: Japan has a range of gadgets to support the ageing population. It allows young relatives to keep in touch with their elderly relatives.</p><p> This includes an online kettle that automatically sends emails to up to three people when its switched on. </p><p> Also, internet-linked sensors that can be attached to fridge doors and bathroom mats.</p></li><li><p>Population pyramids</p><p>LICHIC</p><p>Short life expectancy</p><p>High birth rate</p><p>Long life expectancy</p><p>Low birth rate</p></li><li><p>Key wordsLife expectancy the average number of years a person is expected to live</p><p>Dependent population the people aged under 15 and over 65 that are relying on the rest of the population to work and pay taxes to ensure a good quality of life (health care, education, etc.)</p><p>Economically Active Population people aged 15-65 who are of working age</p><p>Economic Dependency Ratio the % of people working compared to those people who are not. A high % of people working is good for the economy.</p></li></ul>
