How does population increase?
The birth rate is higher than the death rate
What does a population pyramid with a wide base represent?
A developing country
What does a population pyramid with a Narrow base represent?
A developed country
What does a narrow or wide top of a population pyramid
represent?
- Narrow- low life expectancy and high death rate
- Wide-high life expectancy and low death rate
What does a narrow or wide base of a population pyramid
represent?
- Narrow-low birth rate
- Wide-high birth rate
What are the three age factors that a population pyramid are split into?
- 0-16 young independents
- 16-65 economically active
- 65+ elderly dependants
What are the 7 social and economic development indicators?
- SOCIAL-how acountry uses its wealth to improve the quality of life of its people
- Adult literacy
- Energy used per person
- Infant mortality rate
- Life expectancy
- ECONOMIC-they measure the wealth and industrialisation of a country
- GDP
- People employed in agriculture
- GNP
What is the definition of GDP?
The value of goods produced and services provided in a country in one year. Indicates the wealth of the average person.
What is the definition of GNP?
Similar to GDP but it also includes services earned abroad
What is the definition of people employed in agriculture?
A country with a high proportion of its people employed in agriculture will have little industry to produce wealth. In addition its farms are likely to be small and unprofitable. so a high percentage of people employed in agriculture is a good representation of a developing country and vice versa.
What is the definition of adult literacy?
Percentage of people aged 15 and over who can read and write, shows that a country has good education services.
What is the definition of energy used per person
The amount of energy used in a country, countries producing much wealth will use a lot of energy. People with a higher standard of living will use a lot of petrol in their cars and electricity in their homes.
What is the definition of infant mortality rate?
The amount of children who die before they are one year old indicating how good a countries health services and living conditions are..
What is the definition of life expectancy?
The average period a person may expect to live and shows how good a countries health services and living conditions are.
What are solutions to rapid population growth and how do these affect the population growth?
- One child policy in China - means that less people will have more than one child as they will be fined and those that stick to the rule will get incentives like better education, free health care and preferential housing.
- Family planning clinics/Sex ed - means that people are better educated about protection and the reality of bringing up a child
- Abortion and sterilisation more widely available - means that unplanned births can be terminated
- Contraception being more widely available - results in less unplanned births happen
• Better education for females - if females are better educated they are more likely to get better jobs and have kids later on in life when fertility rates are lower
