This document explores the formula for calculating the rate of natural increase, defined as the difference between the crude birth rate and the crude death rate, divided by ten. Various countries are examined, with specific rates detailed for Paraguay, Australia, China, Italy, and more. Additionally, it discusses the stages of population growth in relation to birth and death rates, highlighting factors affecting these rates, including economic conditions, healthcare advancements, and societal norms. A comparative analysis of aging populations in developed nations is also included.

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 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.
