In which stage of the demographic transition does most population growth occur?
Most LEDCs are at stage 2 or 3 (with a growing population and a high natural increase). Most MEDCs are now at stage 4 of the model and some such as Germany have entered stage 5. As populations move through the stages of the model, the gap between birth rate and death rate first widens, then narrows.
What are the 4 stages of the 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 two stages of the demographic transition model does population grow rapidly?
In Stage 2, the introduction of modern medicine lowers death rates, especially among children, while birth rates remain high; the result is rapid population growth.
What are the three main components of population change?
The main components of population change are births, deaths, and migration. “Natural increase” is defined as the difference between live births and deaths. “Net migration” is defined as the difference between the number of people moving into an area and the number of people moving out.
What are the major determinants of population change?
Fertility, mortality and migration are principal determinants of population growth. Population change depends on the natural increase changes seen in birth rates and the change seen in migration. Changes in population size can be predicted based on changes in fertility (births), mortality (deaths) and migration rates.
What are the factors affecting global demography?
Often economic growth and economic development have led to a decline in population growth, but there are no hard and fast rules and other factors, such as availability of family planning, social expectations and government intervention can play an important role.
What three factors affect the size and age of population?
Population growth rate is affected by birth rates, death rates, immigration, and emigration.
What is the relationship of demography to globalization?
Globalisation has also its own demographic model: swift increase of individuals mobility from the rural area and from the farming lifestyle to the urban area which is closer linked to global trends with respect to food, markets, fashion and leisure.
How does demography affect economy?
Demographic change can influence the underlying growth rate of the economy, structural productivity growth, living standards, savings rates, consumption, and investment; it can influence the long-run unemployment rate and equilibrium interest rate, housing market trends, and the demand for financial assets.
How does population growth in other countries affect us?
Population growth in other countries cause accelerated immigration to the USA because of better income, health care, job opportunities, etc. But mostly poor, unskillful people tend to move to the USA from other developing countries. In high population growth rate countries some wars or conflicts raise.
What are some positive impacts of population growth?
However, I believe that population growth has positive effects on societies. These include economic benefits such as expansion of tax bases and increased consumer spending at local businesses, as well as benefits derived from innovations by cultures seeking to keep up with growing populations.
What is the relationship between population growth and economic growth?
Population growth enlarges labour force and, therefore, increases economic growth. A large population also provides a large domestic market for the economy. Moreover, population growth encourages competition, which induces technological advancements and innovations.
What is the role of population growth and economic growth?
Population growth plays a conflicting role in the development process of a country. It helps economic development and it retards economic development. To the Greek philosophers, about 2,500 years ago, population growth was undesirable as it adversely affects economic development.
What is the link between population and development?
The quantity, quality, structure, distribution, and movement of a population can help or hinder the rate of economic development. A developed country with low population density and a low percentage of employable people needs an increase in population in order to keep up with economic development.
