Last updated 28 Apr 2018
The DTM is a model of population change from a low stable population to a high stable population as a result of a preliminary fall in the death rate from a high level (45/1000 p.a. to around 9/1000 p.a.) to be followed later by a fall in the birth rate. The time-lag between the decline in the two measures of natural population change results in a period when there are far fewer people dying than being born, resulting in a phase of rapid population growth.
