Population Dynamics Flashcards
Crude Birth Rate
the number of births in a total population in a year, given as a rate per 1000 people
Total Fertility Rate
the average number of children a person is likely to have if they live to the end of child-bearing age
Replacement Rate
the fertility rate required to keep a population stable (neither increasing or decreasing)
Crude Death Rate
the number of deaths in a total population in a year, given as a rate per 1000 people
Natural Increase
the difference between crude birth rate and crude death rate of a population, with births exceeding deaths, usually expressed as a percentage
Life Expectancy
the average number of years a person might be expected to live, usually measured from birth
Infant Mortality Rate
the number of deaths of children under one year old per 1000 live births in a year
Child Mortality Rate
average number of deaths of children under the age of 5 per 1000 children in a year
Ageing Population
A population where older people become proportionally larger share of the total population. Increased percentages of the elderly (usually 65 and over), increased median age of total population, decreased percentages of children
Demographic Transition Model
