Stage 1 of the DMT
High stationary Death rate is high Birth rate is high Rate of natural increase is low UK position:before 1760 Examples remote tribes in the tropical rainforest
Stage 2 of the DMT
Early expanding Death rate is falling Birth rate is high Rate of natural increase is high UK position: between 1760 and 1900 Examples: Bangladesh and Niger
Stage 3 of the DMT
Late expanding Death rate is falling Birth rate is falling Rate of natural increase is high UK position: 1900 to 1950 Examples: India, Brazil and Mexico
Stage 4 of the DMT
Low stationary Death rate is falling Birth rate is low Rate of natural increase is very low or stable UK position: since 1950 Examples: USA, France and Denmark
Stage 5 of the DMT
Declining Death rate is rising Birth rate is very low Rate of natural increase is negative UK position: the UK could soon enter this stage Examples: Japan, Russia and Germany
Where is population increase mostly occurring?
Population increase mainly occurs in low income and middle income countries such as Africa the Middle East and parts of South America and south Asia
