Population Flashcards
Crude Birth Rate(CBR)
The number of births per thousand individual in a population per year
Crude Death Rate
The number of deaths per thousand individuals in a population per year
Natural increase rate
The number of human growth expressed as a percentange chanage per year
Double time
The time it takes for the population to double in size
Total fertility rate
Average number of children each women can have over a life time
Dependecy ratio
Measure of the proportion of the working-age population (typically aged 15-64) compared to the dependent population (children under 15 and adults over 64).
Dependecy ration formula
(Population aged 0-14 + population 65+/Populaion aged 15-64) x 100
CBR caculations
Birth/Population x 100
CDR caculations
death/population x 100
NIR Caculations
(crude birth rate-crude death rate)/10
Population density caculations
Total poulation/area(km)
TFR caculaition
addition of fertile(15-49)/5
