- Stage 1: High Population Growth Potential.
- Stage 2: Population Explosion.
- Stage 3: Population Growth Starts to Level Off.
- Stage 4: Stationary Population.
- Stage 5: Further Changes in Birth Rates.

What are the 4 stages of the demographic transition in order?
The demographic transition model was initially proposed in 1929 by demographer Warren Thompson. The model has four stages: pre-industrial, urbanizing/industrializing, mature industrial, and post-industrial.
What are the stages of demographic transition theory explain the stages?
Stage 1- high and fluctuating birth and death arte and population growth remains slow Stage 2- high birth rate and declining death rate and rapid population growth rate Stage 3- Declining birth rate and low death rate and declining rate of population growth Stage 4- low birth and death rate and slow population growth …
How do you calculate demographic transition?
It is calculated by dividing the number of deaths in a country by the total population and then multiplying by 1000. This is the change in the total population of a country because of births and deaths (ie not including migration).
Why is China in stage 4 of the demographic transition model?
In Stage 4 of the Demographic Transition Model (DTM), birth rates and death rates are both low, stabilizing total population growth. That being said, Stage 4 of the DTM is viewed as an ideal placement for a country because total population growth is gradual.
What are the 4 stages of population pyramids?
The stages of demographic transition are – (i) high stationary stage; (ii) early expanding stage; (iii) late expanding stage; (iv) low stationary stage and (v) declining or negative growth rate stage. These stages are represented by dramatically different population pyramids (Fig. 4).
What is Stage 2 of demographic transition called?
Like Afghanistan, many countries in Stage 2 are categorized as “developing.” The rates of birth and death are both the cause and effect of social and political factors within a country.
How many stages are there in demographic transition theory?
four stages
The original Demographic Transition model has just four stages, but additional stages have been proposed. Both more-fertile and less-fertile futures have been claimed as a Stage Five. Some countries have sub-replacement fertility (that is, below 2.1–2.2 children per woman).
What is demographic transition theory explain its three stages with suitable diagram?
Transition theory is a three staged model : (i) First stage of high fertility & high mortality. (ii) Second stage –Fertility high and mortality declines. (iii) Third stage both fertility and mortality declines.
What is CBR and CDR?
PIP: Both the crude birthrate (CBR) and the crude death rate (CDR) represent a simple concept: the number of births or deaths which occur in a given year per 1000 population. They can also be used to calculate another fundamental measure, the rate of natural increase.
Why is Canada a stage 4 country?
The birth rates are decreasing and the death rates are increasing and it appears that Canada is in Stage 4 of the Demographic Transition Model. Once the country is at Stage 4 the birth and death rates will stabilize and be equal to each other which makes the country fully developed.
Why is Australia a stage 4 country?
Right now, Australia appears to be in the fourth stage of the demographic transition model. This fourth stage characterizes low stability in which both birth rates and mortality rates show a downward trend. Secondly, mortality rates have declined with increased survival until old age.
What are the four phases of demographic transition?
The four phases of demographic transition are as follows: Phase 1: primitive stability, Phase 2: epidemiologic transition, Phase 3: fertility transition, and Phase 4: modern stability. The first phase which is primitive stability is defined by the high birth and the high death rates.
What countries are in the stages of demographic transition?
The extent to which it applies to less-developed societies today remains to be seen. Many countries such as China, Brazil and Thailand have passed through the Demographic Transition Model (DTM) very quickly due to fast social and economic change.
What stage of the demographic transition is the US in?
That being said, Stage 4 of the DTM is viewed as an ideal placement for a country because total population growth is gradual. Examples of countries in Stage 4 of the Demographic Transition are Argentina, Australia, Canada, China, Brazil, most of Europe, Singapore, South Korea, and the U.S.
What is an example of demographic transition model?
The demographic transition theory is a model that tries to explain the stages of population growth for nations over a period of time. For example, before industrialization many nations had significant high death and birth rates; however, this allowed the population to remain stable.
