The major factor affecting the population is the growth of the population which depends on the fertility of the population. 2. The second factor affecting the population is the mortality rate, as the fertility rate increases the population the death rate decreases it thus creating a balance in the population size.

Which are the components of population growth in India?

Birth rate is a major component of growth because in India, birth rate has always been higher than the death rate.

What is population growth Class 8?

A rapid growth in population is referred to as population explosion. If the birth rate is more than the death rate, then there is an increase in population. If the death rate is more than the birth rate, then there is a decrease in the population. A decrease in population is known as depopulation.

What are the main components of population structure?

Population structure (numbers, density, sex, and age), fertility, mortality, and migration are fundamental demographic variables. They are also the fundamental variables of microevolution at the population level.

What are the components of population composition?

Population composition means all the characteristics of population by which population is separated from one another, i.e. age, sex, settlement, occupation, education, and life expectancy. Components of Population Composition: The major components of population composition are age, sex, literacy, settlement, etc.

What are the 5 components of demography?

Therefore, demography is the scientific study of human population primarily with respect to size, structure, distribution and change (development). In short, demography is the scientific study of population. Population change results from interaction of demographic components, viz, birth, death and migration.

What are the cause of population growth Class 9?

Birth rate, migration, emigration are the major causes of population change.

What do you mean by growth of population?

Population growth is the increase in the number of humans on Earth. For most of human history our population size was relatively stable. But with innovation and industrialization, energy, food, water, and medical care became more available and reliable.

What is the main cause of rapid population growth in India Class 9?

The main cause of the rate of growth of the Indian population has been the rapid decline in death rates. Till 1980, high birth rates and declining death rates led to a large difference between birth rates and death rates resulting in higher rates of population growth.

What are two component of population growth?

Population change includes two major components: natural change (births minus deaths) and net migration (in-migrants minus out-migrants).

What are the principal components of population dynamics?

In practice investigations and theory on population dynamics can be viewed as having two broad components: first, quantitative descriptions of the changes in population number and form of population growth or decline for a particular organism, and second, investigations of the forces and biological and physical ...

What is population discuss about population growth and its characteristics?

Population growth rate (r) is how fast a population changes in size over time. A positive growth rate means a population is increasing. A negative growth rate means it is decreasing. The two main factors affecting population growth are the birth rate (b) and death rate (d).

And the projected growth in demand is staggering.

What are the causes of high population growth?

What are the six components of demography?

Demographics can include any statistical factors that influence population growth or decline, but several parameters are particularly important: population size, density, age structure, fecundity (birth rates), mortality (death rates), and sex ratio (Dodge 2006).

What are the components of population education?

3 major elements of population education are 1) determinants of population growth; 2) demography; and 3) consequences of population growth. 2 other aspects, generally called "sex education," can be added: human reproduction and family planning policies and programs.
