**Demography** - the study of population **Population distribution** - the spread of the population e.g. evenly, densely or sparsely spread. **Population density** - number of people in a given area, usually in one kilometre squared **Densely populated** - lots of people in a given area **Sparsely populated** - not many people in a given area **Exponential growth** - when something increases 1,2,4,8,16,32 and so on **Arithmetic growth** - when something increases 1,2,3,4,5,6,7,8, and so on **Natural increase / decrease** - the change in the population governed by the number of births minus deaths **Birth rate** - number of births per 1000 people in a given year **Death rate** - number of deaths per 1000 people in a given year **Infant mortality rate** - of every 1,000 infants born, the number that die before reaching their first birthday. **Fertility rate** - average number of babies a woman can expect to have in her lifetime **Life Expectancy** - the average number of years a person can expect to live until **Pattern of mortality** - the spatial distribution of deaths worldwide, by region or by country **Pattern of fertility** - the spatial distribution of births worldwide, by region or by country **Dependency ratio** - the ratio of the non-working population (economically inactive) - people under 15 or over 65-to the working population (economically active) - people 15-64. **Population pyramid** - a graph showing the size of a population by age and gender **Ageing population** - where the median age of the population rises leading to a larger proportion of the population being of older age **Migration** - the movement of people from one place to another, which can occur on a temporary or permanent basis and over a short or long period of time **Migrant** - a person who moves from one place to another temporarily or permanently and for a short or long period of time **International migration** - people moving from one country to another e.g. Australia to the UK **Domestic migration** - people moving from one part of a country to another e.g. NSW to QLD **Rural to urban migration** - people moving from lower populated rural areas to large urban centres e.g. Barossa Valley to Adelaide **Counter-urbanisation** - people moving away from major urban areas to urban fringes or back to rural areas **Push factors** - negative aspects of a place that may cause a person to leave there **Pull factors** - attractions of another place that would influence a person to move there **Involuntary migration** - people who are forced to move, possibly to avoid war, disease, famine, persecution etc **Voluntary migration** - people who choose to move, possibly for lifestyle, employment, family reasons etc **Refugee** - a person who "owing to a well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group, or political opinion, is outside the country of his nationality, and is unable to or, owing to such fear, is unwilling to avail himself of the protection of that country…" **Asylum seeker** - a person who has left their country of origin, has applied for recognition as a refugee in another country, and is awaiting a decision on their application. **Illegal immigrant** - people who enter a country without meeting legal requirements for entry, or residence. **Internally Displaced Person (IDP)** - a person who may have been forced to flee their home for the same reasons as a refugee, but has not crossed an internationally recognised border.

 * Population growth rate ** - The increase in a country's population during a certain period- usually one year- expressed as a percentage of the population when the period began. For example if a country had 100 people at the beginning of the year and by the end of the year had 200 people, the population growth rate would be 100%
