1. Higher Population An Introduction to Higher Population

2. Introduction In October 2011 the worlds population was calculated at 7 billion. This population is set to increase and will reach 8 billion around the year 2050. This population is not evenly spread throughout the world; some areas are sparsely populated while others are densely populated. Estimates suggest that around 75 % of the world’s population live in developing countries which marks a northern/southern hemisphere divide.

13. Answer Areas like Central Europe are densely populated because here the climate is moderate without extremes meaning that people can live and work here comfortably. The land is flatter here which means it is often more fertile and that building is easier and less expensive here. There is also a high concentration of jobs within Europe which encourages people to live there. At the same time there is also government investment within Europe meaning that there is more money for development. Areas like the Amazon are not densely populated as they are too remote to get there. This means that transportation is difficult and also that industry will not want to set up there. There is also a lack of jobs. The climate is uncomfortable and too humid to work in. Agriculture is difficult as they rain leaches nutrients from the soil.

14. Collecting Population Data LO – To be able to describe and explain how demographic information is collected and the problems associated with this.

15. What is a census? A Census is a survey, which provides detailed, reliable, statistical information of an entire population. It is a count of all people and households by the Government so that they (and all other organisations) can target resources, decide policies and plan services In the UK a census has been taken every ten years since 1801 (except for 1941)

16. What does the census cover? Household Accommodation Type Number of rooms Bathroom facilities Number of cars ownership Personal D.O.B Marital status Education Employment Religion Ethnic origin General health Number of children

17. How effective are they? Many countries are very efficient at collecting regular, reliable counts of their population and therefore valuable data for governments and planners. However, it requires massive amounts of planning and is very expensive (UK census costs approx. £255 million!) Some countries find it very difficult to conduct a census. Data is often inadequate, unreliable or non-existent.

18. Problems

19. Problems taking a Census in an ELDC Nomadic people Are difficult to keep track off e.g. Fulani of the Sahel High Pop Mobility e.g. 300 rural families migrate to Mumbai everyday Expensive Costs are huge and pose an enormous financial burden Enumerators e.g. India’s 1991 needed 1.7 million enumerators Suspicion Homelessness Language e.g. India has over 1 billion people that speak 15 languages in 1650 dialects Social and religious e.g In Jordan’s 1994 census many females omitted Literacy You are expected be familiar with some case studies that reflect the problems associated with taking a census in an ELDC Remote/ mountainous War

21. World Population Change LO – To be able to describe world population change.

22. Fertility, Mortality, Migration Fertility rates, mortality rates and migration rates are continually changing in our world. This fact makes it even more difficult to project population growth.

24. Population Projections for 2150 3 possible projections have been calculated based on UN forecasts If women around the world have 2.5 children world population will reach 27 billion by 2150 If fertility rates are reduced to 1.6 low projection levels would drop the population to 3.6 billion by 2150. Most likely is a medium projection where women have 2 children, this will stabilise the population at around 11 billion by 2150.

46. Migration LO – To be able to describe migration patterns and explain the positive and negative impacts of migration.

47. Key Terms Migration is ‘a movement’ of people from one home to another. It can be applied to temporary changes, including seasonal and daily movements. Emigrant is people who leave a country Immigrant are newcomers to a country The migration balance is the difference between the number of emigrants and immigrants

48. Types of Migration Permanent External (international) Internal VoluntaryForcedRuralUrbanRegional West Indies to UK African slaves to USA LEDCs UK conurbations NW to SE UK

49. Types of Migration (continued) Semi-PermanentSeasonalDaily Several years Several months/years Commuters Migrants workers in France/Germany Harvest/holidays/uni students SE England

50. International Migration (Voluntary) People looking for an improved quality of life and personal freedom Employment (e.g. higher salaries, better job) Trade and economic expansion Better climate Better social amenities (e.g. hospitals, schools) To be with friends and relatives

51. International Migration (Forced) There is no personal choice but to move due to natural disaster or to economic or social imposition Religious and/or political persecution Wars (refugees) Forced labour (e.g. slaves or POW) Racial discrimination Lack of food due to famine Natural disasters Overpopulation

53. Barriers To Voluntary Migration: Lack of money Lack of awareness of opportunities Lack of skills Government restrictions To returning to Area of Origin: Insufficient funds Lower standard of living Racial or political problems

54. Consequences: for the Migrant May find better employment May have a better standard of living Stressful May not speak the language May find gaining employment difficult Away from family and friends and may feel lonely and isolated

55. Consequences: for the Area of Origin Less pressure on services and resources May send money back from host area Lack of workers (age 20-35) may lead to economic slump Very few children born Increasing elderly population Creates ghost towns Nobody to do manual work

56. Consequences: for Host country Plentiful supply of key workers Increase number of children born (stop underpopulation) May bring new skills May depress local wages Strain on local services Competition for employment Racial tension
