Important Population Definitions Demography – the study of population and its’ changes and patterns. Population Density – the average number of people per square kilometre. Population Growth Rate – in %, refers to the speed at which a population grows per year. (ie. World = 1.092%) Birth rate – refers to the number of live births in a country per 1000 population per year. (ie. World = 19.12/1000) Death Rate – refers to the number of deaths in a country per 1000 population per year. (ie. World = 8.12/1000) Natural Increase – birth rate higher then death rate. Natural Decrease – death rate higher then birth rate. Infant Mortality Rate - # of infant deaths per 1000 live births. (World is at 41.61/1000 live births.)
Definitions Continued Doubling Time - # of years required for a population to double. Overpopulation – condition where organism’s numbers exceed the carrying capacity of its habitat. Most commonly refers to the relationship between human population and its environment. Dependency load – The ratio of people under 15 and over 65 in any population, most commonly shown to reveal the strain on the working class. Population Momentum – When the rates of growth are expected to decline but the actual population members continue to grow. Why is this happening in Canada? Carrying capacity – the max number of people that a habitat can support. Total fertility rate – The average number of children each women will have in her lifetime.
