Key Terms• LEDC• MEDC• Birth Rate (BR)• Death Rate (DR)• Migration• Age Group• Dependents• Economically active• Life expectancy• Natural Increase• Declining, Increasing and Balanced Populations• Population Distribution• Population Density• Population Structure• Population Pyramid• Demographic Transition Model

• LEDC – Less Economically Developed Country

• MEDC – More Economically Developed Country

• Birth rate – number of births per 1,000 of the population per year

• Death rate - number of deaths per 1,000 of the population per year

• Migration – the movement of people in and out of an area.

• Age Group – a grouping of certain ages to aid in collection and use of statistics

• Dependents – people who rely on others for support (social or economic)

• Economically active – people who are of working age

• Life expectancy – how long a person is expected to live from a certain age

• Natural Increase – the rise of a population due to more births than deaths

• Declining, Increasing and Balanced Populations• Declining = more deaths than births• Increasing = more births than deaths• Balanced = birth and death rates are equal

• Population Distribution – The way in which people are spread across a given area (local, regional, national, global)

• Population Density – Population density is the average number of people per square kilometre

• Population Structure – The parts or composition of a population

• Population Pyramid – a graph that shows the distribution of various age groups in a population (not necessarily a pyramid!)

• Demographic Transition Model – a graph that shows a population transition from high birth and death rate, to a declining overall population – has 5 stages.

Important Concepts

• Population Growth• Population Structures• Population Change
