At present the world's population is growing quickly, but… this has not always been the case.

Has the increase in MEDCs been similar to the increase in LEDCs?

DEMOGRAPHIC TRANSITION MODEL

DTM shows population change over time,how birth rate and death rate affect the total population of a

country

HIGH STATIONARY STAGE

Birth and death rates are both very high (35-40 per thousand).

Slow population growth

All human populations up until the late 18thC.

- deseases- food shortages- natural desasters

EARLY EXPANDING STAGE

The death rate declines while the birth rate remains high.

Rapid rise in population growth (a "population explosion")

The decline in the death rate in Europe began in the late 18th.CMany LEDCs entered stage 2 in the second half of the 20th C.

Gap between death and birth rates

LATE EXPANDING STAGE

The gap between birth and death rates narrows due to the decline in birth rates.

Total population is still rising, but the growth begins to slow down

LOW STATIONARY STAGE

The death rate and birth rate remain low.

Slow population growth

The birth rate fluctuates due to changes in the economy.

Most MEDCs are now at this stage

Now a new stage -Declining stage- has

been added as it is relevant to an increasing

number of MEDCs in the 21st century.

The original model didn´t take

into account the fact that some

countries now have a

declining population.

DECLINING STAGE

The death rate remains low or increases a little (ageing population).

The birth rate keeps decreasing.

Negative population growth.
