First stage (High stationary): This stage is characterised by high bih and death rate which cancel out each other and the population remains stationary. Second stage (Early expanding): The death rate begins to decline, while the bih rate tends to fall. Many countries in South Asia and Africa are in this phase. Third stage (late expanding): The death rate of the population is on declining trend. The bih rates are also falling. The population continues to grow as bih rate exceeds deaths. India is currently in this phase. Fouh stage (Low stationary): This stage is characterised by low bih and death rate with a result that the population becomes stationary as in Austria in 1980 to 1985. Fifth stage (declining): Population begins to decline because th bih rate is lower than the death rate. Ref: Park, 22nd edition pg: 441
