Question	Answer
BIRTH RATE	Amount of live births per 1000 people
DEATH RATE	Amount of deaths per 1000 people
POPULATION DENSITY	Amount of people per unit of area
EXPONENTIAL GROWTH	Growth whose rate becomes more and more rapid in proportion to the growing total
NATURAL CHANGE	The difference between the birth rate and the death rate, expressed as a percentage
STAGE 1 OF DTM	Few elderly people in society - short life expectancy. Sides narrow in quickly due to high death rate
STAGE 2 OF DTM	Side less concave as death rate drops. A few more elderly people in population. Base a little narrower
STAGE 3 OF DTM	Straighter sides as more people live into old age. Birth rate decreasing
STAGE 4 OF DTM	Most people die in old age - life expectancy is high. Birth rate reducing causing concave shape
STAGE 5 OF DTM	Increasing proportions in the very elderly group. Middle-aged generation is much larger than those of children because of low birth rate
