Population

  1. 1. The number of births in a year per thousand population. As in many developing countries, birth rates have been falling in the UK for many years. The number of deaths in a year per thousand population. As in many developed countries, the death rates in the UK are low by international standards 9.7 Essentials 1 / 5 Birth and Death Rate Births and Deaths in the UK
  2. 2. 9.7 Essentials 1 / 5 Population: UK and Poland This shows the population structure of a place by displaying the numbers in each age group as a bar graph. The shape of the pyramid shows the proportion of young and older people, males and females and indicates the birth and death rates. Pyramids allow us to predict future natural increases, as they show the numbers of people of child-rearing age. http://www.medindia.net/patients/calculators/worldpopulation.asp
  3. 3. • Natural increase The number of births minus the number of deaths, i.e. the change in population due to the differences between birth and death rates. • Life expectancy The average number of years a person born in a particular country is expected to live. • Ageing population The process taking place in many developed countries, where fewer people are being born, leading to an increase in the average age of the population. An ageing population can put more strain on the working population to supply funding for pensions and healthcare. • Fertility rate The average number of children born per Woman. In the UK the fertility rate has fallen 9.7 Essentials
  4. 4. 9.7 Essentials 1 / 5 9.7 Essentials 9.7 Essentials Total UK net migration 1991-2006 Migration The permanent, seasonal, or temporary movement of people. This can range from permanent international migration to daily flow of commuters from the suburbs, to the city centre Immigration The movement of people into a country from outside. In 2006, 591,000 people entered the UK. 68,000 were from Poland. Emigration The movement of people outward from a country. In 2006, 400,000 people emigrated from the UK- mainly to Australia, Spain, France and New Zealand Net Migration The number of people arriving (immigrants) minus the amount leaving (emigrants). In 2006, net migration to the UK was 191,000 Migration
  5. 5. The expected future changes in a country’s population on which many government and planning decisions are based. The UK population is projected to increase 10.5 million, from 60.6 million in 2006, to 71.1 million by 2031. 53 per cent of this will be due to natural increase and 47 per cent due to migration. Dependency ratio The number too old or young to be working divided by the number of working age (16- 64 years). This ratio is increasing in the UK and Poland, as birth rate declines, the population ages and larger number of retired people are no longer working. Population Project 9.7 Essentials
