What happens to population growth in each stage of the demographic transition?

What happens to population growth in each stage of the demographic transition?

In stage 1 the two rates are balanced. In stage 2 they diverge , as the death rate falls relative to the birth rate. In stage 3 they converge again, as the birth rate falls relative to the death rate. Finally in stage 4 the death and birth rates are balanced again but at a much lower level.

What is Stage 2 of the demographic transition model called?

Stage two has a high birth rate, but the death rate drops. Because of this the natural increase rate goes way up! A number of countries in Sub-Saharan Africa (Niger, Democratic Republic of the Congo, Somalia) are currently in stage two. The population of these countries is rising and their doubling time is short.

How does demographic transition affect global population?

During this stage, the birth rates remain high but the death rates drop, causing the overall population to increase. The theory of demographic transition predicts how a population will change over time in regards to the mortality and fertility rates as well as age composition and life expectancy.

What are the stages of demographic transition theory explain the stages?

Stage 1: This is a state of high birth and death rates culminating in low population growth overall. Stage 2: With a consistently high birth rate and decreasing death rate, population growth surges. Stage 3: As the birth rate falls and the death rate remains low, the population continues to increase.

What are the three phases of demographic transition?

Stages of Demographic Transition

• Pre-Industrial Stage. The first stage of the demographic transition is the pre-industrial stage.
• Transitional Stage. Following the pre-industrial stage is the transitional stage.
• Industrial Stage.

What are the 4 stages of demographic transition?

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 country is most likely to be in stage 4 population growth?

China

Why is Canada a stage 4 country?

Canada’s population is replacing itself because there are more births than deaths. 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.

Why is India a Stage 3 country?

In stage 3 there is already a low death rate as well as a declining birth rate, therefore leading to a slight increase in population. Lower infant mortality rate. A more industrialised way of life. The want for more material possesions as well as women being able to go out to work.

When did India become a stage 3 country?

Thus, India’s population entered the third stage of transition sometime in the close of the 1960s. As decline in the death rates was much more rapid, the rate of natural increase in the population went up from 1.2 to 1.3 per cent during 1921-51 to 2 to 2.2 per cent during 1951-81.

Which stage has the highest NIR?

NIR= % of growth or decline in the population of a country per year. Africa and Southwest Asia have the highest NIR, while Russia and Europe have negative rates.

What countries are Stage 5?

Possible examples of Stage 5 countries are Croatia, Estonia, Germany, Greece, Japan, Portugal and Ukraine. According to the DTM each of these countries should have negative population growth but this has not necessarily been the case.

Is Germany in stage 5 of the DTM?

Germany is currently in the theoretical stage 5 of the demographic transition model because the birth rates fall below the death rates causing the population not to naturally replace itself. Also the life expectancy for old people is really high.

What is Stage 2 of population pyramid?

Stage 2 of the Demographic Transition Model (DTM) is characterized by a rapid decrease in a country’s death rate while the birth rate remains high. As such, the total population of a country in Stage 2 will rise because births outnumber deaths, not because the birth rate is rising.

What do population pyramids show?

A population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population. The graphic starts from youngest at the bottom to oldest at the top.

Which are two main factors that cause population change?

Three primary factors account for population change, or how much a population is increasing or decreasing. These factors are birth rate, death rate, and migration.
