Population structure means the 'make up' or composition of a population. Looking at the population structure of a place shows how the population is divided up between males and females of different age groups. The structure of a population is often of greater importance than numbers alone.
Population structure is usually shown using a population pyramid. A population pyramid can be drawn up for any area, from a whole continent or country to an individual town, city or village.
A population pyramid tells us how many dependants there are. There are two groups of dependants - young dependants (aged below 15) and elderly dependants (aged over 65). Dependants rely upon the working population for economic support. As birth rates fall and people have smaller families, the number of young dependants is falling and the number of elderly dependants is rising.
The population structure of the UK has changed since 2001 as a result of low birth and death rates, together with migration into and out of the country. The population pyramid above shows these changes. There has been:
This is partly due to the higher birth rates of migrants who have entered the country in the last 10 years. Many migrants are of reproductive age. In addition, they may have a religious culture that forbids the use of contraception.
The majority of people who migrate are young and in search of work and a better life. More men tend to migrate than women.
