A population pyramid is a graphical representation showing the distribution of various age groups in a population, which forms the shape of a pyramid when the population is growing.
Imagine stacking blocks where each block represents an age group. The bottom blocks are wider representing younger people while top blocks get narrower representing older people. That’s your typical "pyramid" shape for growing populations!
Dependency Ratio: This measures the pressure on productive population by dependent parts (children and elderly). Like having one worker carrying three backpacks – one for himself, one representing children and another for elderly dependents.
Cohort: A cohort is any group of individuals who share a common demographic characteristic. It's like being in the same school grade - everyone is roughly the same age.
Age-Sex Ratio: This term refers to the proportion of males to females in a given population. Imagine having 10 apples (males) and 15 oranges (females), your ratio would be 10:15.
