Population pyramids are graphs that show population structures, ie how many males and females of different age groups are in the population in each place. Population structures change from place to place and over time. The population pyramids for the countries below are different shapes.

The pyramid for Kenya has a very wide base. This means that there is a high proportion of young people. The top is quite narrow which means there are fewer people in the older age groups. This type of pyramid is more likely to occur in a developing country where birth rates are generally higher.

The pyramid for Japan is a different shape. It does not look like a pyramid. The base is not as wide as the Kenyan pyramid. The middle is wider and the top is taller. This type of pyramid is more likely to occur in a developed country where birth and death rates have fallen.

What does this mean?

A wide base means there are lots of young people, and suggests a high birth rate.

A narrow base means a smaller proportion of young people, suggesting a low birth rate.

A [ wide middle, tall pyramid means an ageing population, suggesting that there is a long life expectancy life expectancy : The average number of years a person is expected to live in a particular place.] .

Some reasons for high birth rates include:

Some reasons for falling death rates include:

Remember, though, that the shape of pyramids can also be affected by . This population pyramid for the UAE shows the effects of lots of male workers arriving to work in these countries.

UK ageing population

The United Kingdom has quite a narrow base but a large middle and top. This means we have an ageing population.

In the UK:

an increasing proportion of the population are over 65

in 2005, 16 per cent of the UK population was over 65

by 2034, 23 per cent of the population is expected to be aged 65 and over compared to just 18 per cent aged under 16

the fastest-growing age group is those over 85 years

women tend to live longer than men but the gap between the life expectancy for males and females is reducing

Ageing population can bring benefits, such as more experience and knowledge. But it also increases the cost of healthcare and adds to the government spending, as they have to pay everyone a pension (retirement income).
