Demographic Transition Model
- The model shows the change from high birth rate and death rate to low birth rate and death rate over time
- Typical of less developed countries: high proportion of children, high death rate, and short life expectancy
- Factors contributing to high birth rate and death rate: lack of access to birth control and healthcare, limited knowledge about preventing or curing diseases, and poor sanitation and hygiene
Stages of the Demographic Transition Model
- Stage 1: High birth rate and death rate, typical of less developed countries
- Stage 2: Shrinking population pyramid, lower numbers of younger people, more ageing people, and long life expectancy, typical of very developed countries
Differences in Development Around the World
- More Economically Developed Countries (MEDCs) have higher literacy levels and lower infant mortality rates
- Social measures: life expectancy, death rate, infant mortality rate, percentage of population undernourished, and percentage of country's budget spent on healthcare
Environmental Indicators
- Measure the extent of human impact on the environment
- Examples: percentage of polluting gases in the atmosphere, quality of water, and drop in fish stocks in the sea
Human Development Index (HDI)
- Adopted in 2010 as a more reliable indicator than GDP
- Takes three indicators into account: life expectancy, adult literacy, and GDP
- Does not consider environmental factors
- Ranks 187 countries, with Norway, Australia, and Switzerland being the top three in 2014
Population Characteristics and Development
- Population growth: increase in a country's population during a year, expressed as a percentage of the population
- Calculated as the difference between birth rate and death rate
- Birth rate: number of births per 1000 population in a year
- Death rate: number of deaths per 1000 population in a year
