Demographic change describes the changes in population size and structure caused by changes in birth rates, death rates, and by migration. Demographic change in the Western developed countries of today is marked by low birth rates below population replacement and by rising life expectancy..
How is demographic transition?
In demography, demographic transition is a phenomenon and theory which refers to the historical shift from high birth rates and high death rates in societies with minimal technology, education (especially of women) and economic development, to low birth rates and low death rates in societies with advanced technology, .
What are the 4 stages of the demographic transition model?
The model has four stages: pre-industrial, urbanizing/industrializing, mature industrial, and post-industrial. In the pre-industrial stage, crude birth rates and crude death rates remain close to each other keeping the population relatively level..
What is the demographic cycle?
The demographic cycle, or population cycle, refers to the evolution over time of the population profile of a country, region or other defined geographical area. A population cycle theory has been postulated in terms of the socio-economic history of industrialized countries..
What is the demographic gap?
On one side of this divide are mostly poor countries with relatively high birth rates and low life expectancies. On the other side are mostly wealthy countries with birth rates so low that population decline is all but guaranteed and where average life expectancy extends past age 75, creating rapidly aging populations.Dec 1, 2005.
What is the DTM model?
This model—the Demographic Transition Model—suggests a shift from high fertility/high mortality to low fertility/low mortality, with an intermediate period of rapid growth during which declining fertility rates lag behind declining mortality rates..
What is the meaning of demographic gap?
The demographic gap refers to the difference between the birth rate and the death rate in a specific population. It is also known as the population growth rate..

Demographic gap is the difference between birth rate and death rate that develops when a country undergoes demographic transition.
History
The theory is based on an interpretation of demographic history developed in 1930 january 16th by the American demographer Warren
Summary
The transition involves four stages, or possibly five
Stages
In pre-industrial society, death rates and birth rates were both high, and fluctuated rapidly according to natural events, such as drought and disease
Effects on age structure
The decline in death rate and birth rate that occurs during the demographic transition may transform the age structure
Historical studies
Between 1750 and 1975 England experienced the transition from high levels of both mortality and fertility, to low levels
What is the gap between urban and rural areas?
The gap between urban and rural areas: rural areas make up to 44% of the EU’s surface, but 78% of the European population lives in urban areas or functional urban areas Ageing population: due to increasing life expectancy, 30
3% of the population is projected to be aged 65 years or older by 2070 (compared to 20
3% in 2019)
What is the onset of the demographic transition?
The onset of the demographic transition is traced by Galor and Weil ( 2000) and Galor and Moav ( 2002) to the rise in the demand for human capital and the incentive that it provides parents to substitute quality for quantity of children

What is the phenomenon and theory of the demographic transition?
The phenomenon and theory of the demographic transition refers to the historical shift in demographics from high birth rates and high infant death rates in societies with minimal technology, education (especially of women) and economic development, to demographics of low birth rates and low death rates in societies with advanced technology,
Demographic gap is the difference between birth rate and death rate that develops when a country undergoes demographic transition In a demographic cycle, as the country develops and the living conditions improve, there is first a decrease in the death rate in the population But the birth rate continues to remain at a high level
