Question

The annual growth rate in population is related to __________.
A. High birth rate
B. High migration rate
C. Increase in age composition
D. Decline in population.

Answer 1

Hint:The annual average rate of change in population size over a defined period for a given nation, region, or geographic area. The ratio, normally multiplied by 100, between the annual growth in population size and the total population for that year is expressed.

Complete answer:
Population growth refers to a decrease in the number of inhabitants of a country or region over a given period of time. Annual Population Growth Rate refers to the rate at which the number of individuals expressed as a fraction of the original popular of the previous years in a given popular increase over a year. There are three main population change processes: birth rates, death rates and migration.The normal population growth is the contrast between birth rates and death rates.
A. High birth rate:-Birth rates are high for a variety of reasons: lack of knowledge or contraception for family planning. Children are required as workers on farms in rural areas. They are forced to work in the informal sector in urban areas to raise money for their families.Women have a large number of children and there is a high level of infant mortality. Culture/religion means that abortion is inappropriate.
B. High migration rate :-The proportion of immigrants from one country to another differs considerably. It reaches half the population in others, although it's below 0.1 percent in others.
A positive net migration rate exists if the number of immigrants is greater than the number of emigrants. A positive net migration rate shows that more individuals are entering than leaving a region.
 C. Increase in age composition :-In demographic studies, age distribution, also called age composition, is the proportionate number of individuals in successive age groups in a given population.
Age distributions between countries vary largely due to variations in fertility levels and patterns.
For example, a population with persistently high fertility has a large proportion of children and a small proportion of elderly individuals.
D. Decline in population :-A reduction in the population of humans is a drop in the size of the human population due to short-term events such as pandemics, conflicts, famines or other disasters, or to long-term demographic patterns such as sub-replacement fertility or persistent emigration.
The consequences of a population that is deteriorating may also be negative. GDP growth may rise much more slowly or may even decline as the population of a country declines.

Hence, the correct answer is option A.
Note:In China, followed by Japan and Russia, the largest absolute population loss will occur between 2015 and 2050. European countries are in the lead in terms of relative population decline: first Bulgaria, then Latvia, Moldova, Ukraine, Croatia and Lithuania.Seven billion people are still living today, and the Population Reference Bureau estimates that 107 billion people have ever existed. This means that we are not close to seeing more people alive than dead.
