A quick revision of over and under population:



  • There could be unemployment because there are not enough jobs for everyone

  • There could be a shortage of schools and hospitals

  • There could be a shortage of hoses and informal settlements grow

  • Congestion may increase as there are more cars, buses, etc. on the road

  • Prices may increase as demand for houses, resources, etc. increase (inflation)

  • There may be a shortage of clean drinking water, electricity, etc.

  • There may be an increase in air, noise and water pollution e.g. open sewers, fires, etc.

  • The rural-urban fringe may be damaged as informal settlements are built

  • There are a shortage of workers

  • There will be less people paying tax

  • Schools and hospitals may close because there are not enough clients

  • Public transport links might close because of less customers

  • There may be less innovation and development (lee brain power)

  • Not possible to exploit all resources

  • Hard to defend country

  • Necessary to attract migrants
