Population Flashcards
Zero Growth
A population in balance. Birth rate is equal to death rate, so there is no growth or decrease.
Natural decrease (ND)
The death rate is greater than the birth rate.
Exponential Growth
A pattern where the growth rate constantly increases – often shown as a J-curve graph.
Birth Rate (BR)
The number of babies born per 1000 people per year.
Death Rate (DR)
The number of deaths per 1000 people per year.
Natural Change
The difference between birth rate and death rate, given as a percentage.
Natural Increase (NI)
The birth rate is greater than the death rate.
Life expectancy
The number of years a person is expected to live, usually taken from birth.
Newly industrialising Countries (NICs)
These include the Asian ‘tigers’ as well as other emerging industrial nations such as Malaysia, the Philippines and China.
Asian ‘tiger’
One of the four east Asian countries of Hong Kong, South Korea, Singapore and Taiwan, where manufacturing industry grew rapidly from the 1960s to the 1990s.
Demographic Transition Model (DTM)
A theoretical model that shows changes in population information (birth and death rates and population growth) over a period of time.
Replacement rate
A birth rate high enough for a generation to be the same size as the one before it.
Urbanisation
The growth in the proportion of people living in towns and cities.
Rural-to-urban migration
Moving home from a rural area o settle in a town or city.
Age structure
The proportions of each age group in a population. This links closely to the stage a country has reached in the demographic transition model.
