Youthful Populations: Where/Why? • High proportion of young people due to high birth rates and a reduction in infant mortality. • This is due to better nutrition, education and medical care. • This may create problems since the children need feeding, housing, education and eventually a job. • Medical care and education has to be paid for by taxing a proportionally small number of workers.
Youthful Population Structure(Population Pyramids) Seen as a wide base on population pyramids that reflect high birth rates in LEDCs.
Youthful Population Structure (DTM) • Stage 2: • This is where the birth rates are high but the death rates begin to fall. • This results in the population increasing. • Lots of countries in the developing world are at this stage, due to improved medical care, but poor education.
Ageing Populations: Where/Why? • High proportion of elderly people who have survived due to advances in nutrition and medical care. • This creates problems since these people do not work and have to be provided with pensions, medical care, social support, sheltered housing etc. from the taxes paid by a proportionally smaller number of workers. • In addition, an increasing number of young people are employed as care workers for the elderly. This removes them from more productive jobs within the economy and harms a country's competitiveness.
Ageing Population Structure(Population Pyramids) • A population pyramid with a narrower shape, broad at the top, found in MEDCs. This reflects their low birth rates and the greater proportion of elderly people.
Ageing Population Structure (DTM) • Stage 5: • Population has begun to decline. • This leads to an aging population as people are not dying due to good medical care. • Babies are also not being born due to good access to contraception and a stronger desire amongst women to work.
Activity Look at the 2 Case Studies (Africa and Britain), read them, and use 3 colours to highlight: • Causes • Effects • Responses You can also add any other logical explanations you can think of for discussion.
