what is the population of the UK
in 2001 the population was 59 million, 2015 population was 65 million
- population has increased
- growth rate decreased
how does high population density cause housing shortages
- example: London has 60,000 new houses are needed to keep up with the population growth
- a shortage of houses drives up prices so some can not afford to live there
how does high population density lead to water stress
- many areas with higher population have a lower annual rainfall
- causes water stress where there isnt enough water to meet peoples needs
- this requires the transfer of water between areas of water surplus and areas of water deficit
what is the population structure of the UK
- In 2001 highest number of people were betwen 30-39yr olds due to high birth rates in the 1960’s

what is annual rainfall and where is it most comon in the uk
the highest levels of rainfall are in the north and west of the uk
why will the south east of england be an area of server water stress in the future
water stress means that there is hardly any water which could cause shortages of food such as fish as the less water on coastal areas the more fish are being killed off
