Question

The age and distribution of a population is determined by the
a. Timing of births and death.
b. The rate at which population is growing.
c. Both(A) and (B).
d. None of the above.

Answer 1

The way the people are distributed across a particular area is population distribution. This distribution may depend on nationality, locality, geographical factors, and the region.

Complete answer:
The Population of a place is determined by the dimensions of birth and death. It is observed that the world’s population is increasing day by day. This is because the death rate has decreased and there is an increase in the birth rate. This imbalance has led to a population increase. Thus, we can say that life expectancy has improved by improving health and falling in mortality. When the birth rate and death rate remain, equal, the population is stable. If there is a high population density, then there are chances of high birth rates and also higher death rates.

The rate of population increases with the growth of individuals in the population. The less developed countries show more growth in population as the birth rates are more than the death rates. Fertility, migration, and mortality are the major determinants of population size. There are different methods for calculating the rate of population growth. The growing population has a severe effect on environmental problems as the carrying capacity decreases.

Hence, the correct answer is option (C).

Note: Life expectancy means the length of time an organism lives in the population. There is uniform distribution in plants as it is observed that many plant species inhibit the growth of nearby plants. The migration of young adults influences the population.
