The Change of Population Structure of the United Kingdom

Extracts from this document...

Introduction

Tanja D�rdelmann Geography Year 12 Page 1 The Change of Population Structure of the United Kingdom 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 in 5 year age groups. Population structure is usually shown using a population pyramid. A population pyramid can be drawn up for a whole country or an individual town, city or village. It enables to see the births and deaths in particular age groups and the overall life expectancy. It also shows the impact of migration, war, famine and disease. The following graphs show the population pyramids for the population structures of the UK for 2000 and for 2025, using projected figures. The left side of each pyramid shows the number of men in each age group, the right side shows the number of women in each age group. ...read more.

Middle

Many young children died in infancy from Tanja D�rdelmann Geography Year 12 Page 2 infectious diseases. As the century progressed the death rates fell. Improvements in medical care and the development of new drugs have meant that some of these people, particularly women, are living into their 80s and 90s. Another interesting point of this pyramid of 2000 contains the younger part. As mentioned above, there was an increase in birth rates in the 1960s. The people born then became fertile in the 1980s and 1990s, so an increase in birth rates would be expected at that time. This has not happened to the extend predicted because social norms have changed. Young people are less willing to have children due to the increased availability of contraception, abortion and sterilization, the growing importance of material possessions and the desire of women to have careers. ...read more.

Conclusion

At the top of the pyramid, from the age of 75 onwards, females outnumber their male counterparts. The ratio of females to males increases progressively from 1.0 at age 70 to nearly 3.0 at age of 90. Women over 90 outnumber men of the same age by more than 5.0. This reflects the higher life expectancy of women and higher male mortality during the Second World War. Tanja D�rdelmann Geography Year 12 Page 3 Further down the pyramid, people of working age represents about 60% of the total population. Of those people within this age group, 52% were aged below 40. The number of births dropped to approximately 660,000 in 2000 but increased steadily broadening the base of the pyramid. To sum up, population pyramids are not only a kind of graphs. They show us much more as thought and they worth it to watch how the population structure of the United Kingdom, or of any other country, changes over time, because it is always open for unpredicted surprises. ...read more.
