HOMEWORK!!!! YAH!! Monday September 17/2012
RNI • The formula for the rate of natural increase is: • (Crude birth rate − Crude death rate) / 10 • For example, Paraguay's crude birth rate (28.47) - the crude death rate (4.49) is 23.98; divide that by 10 and the result is 2.39%, Paraguay's rate of natural increase.
Question 2 • Australia- 7 or 0.7% • China 5 or 0.5% • CR 1 or 0.1% • Italy -1 or -0.1% • Malawi 32 or 3.2% • Malaysia 16 or 1.6% • Myanmar 9 or 1.9% • Nepal 20 or 2.0% • Papua New Guinea 21 or 2.1% • Swaziland 0 or 0% • Uganda 32 or 3.2% • United Kingdom 4 or 0.4%
Questions 4 • http://www.brightredpublishing.co.uk/Uploads/InsideCatalogueItems/4578_Hgr_Geog.pdf
Questions 5- Stage 1 • • Death rates are high because of • Wars • Famine • plagues and epidemics • a lack of clean water and very basic medical care. • • Birth rates are high because of • a lack of birth control • low marriage age • children work, mainly in agriculture, to add to the family income.
Stage 2 • Death rates drop because of: • surgical advances • the increased availability of medical supplies and the introduction of vaccines for diseases such as smallpox • improved nutrition • sanitation and water supplies • rising wages leading to better personal hygiene. • • Birth rates remain high because of • religious factors • the importance given to men with large families • the low status of women in society.
Stage 3 • Death rates continue to drop with further improvements in • Sanitation • health care and medical facilities. • • Birth rates show a huge drop due to: • the adoption of family planning and the development and spread of contraception • declining infant mortality rates • the desire for consumer goods combined with the increased costs of keeping children leading to smaller families • mechanisation meaning less labourers needed for agriculture and factory work. • Better educational opportunities for women and higher female literacy rates also decrease the desire for large families.
Stage 4 • Birth rates have decreased to roughly the same level as death rates but continue to fluctuate in response to • economic conditions. • Very effective birth control enables people to limit the number of children they want and the average marriage age increases as women pursue careers before starting families. • Migration of young, fit individuals also contributes to the fall in birth rates.
Stage 5 • Death rate shows a possible rise because a greater proportion of the population is elderly. • • Birth rate is low and decreasing as people delay child-rearing or make a lifestyle or economic choice to have only one child.
Question 5 • Italy and the UK both have very large populations of people over the age of 65. The UK has 16.5% of its population over 65 along with Italy who has a percentage of 20.3. While comparing this to China and Malaysia both of these countries have only 9% or less of their population over the age of 65. The developed nations mentioned will have a higher death rate due to the fact that they have more elder making up their population and dying of old age.
