Population

• Birth Rate - the number of babies born annually per thousand people.
• Death Rate - the number of deaths a year per thousand people.
• Natural Increase - the difference between the birth and death rate.
• Infant Mortality - the number of children under 1 that die per 1000 live births.
• Dependants - people that rely on economically active people for their well-being e.g. under 16's and the elderly.
• Dependency Ratio - the number of dependants compared to the number of economically active people.
• Changes to the UK's population:

  • Decrease in marriage
  • Increasing population
  • Ageing population
  • Increased immigration
• Death rates decreased due to improvements in medicine.
• Birth rates decreased due to easier access to contraception, women are more focussed on their jobs, children are expensive to look after and less children needed for work on farms - children survived so no need to have more to replace them.
