Human Resources and Population Dynamics

People are the greatest resource of a nation. All other resources of nature become significant only when people extract their usefulness. It is people with their demands and abilities that turn them into resources. Hence, human resource is the ultimate resource.

Population distribution in the world is uneven because of two factors, Geographical and Social.

<p>People prefer living on plains rather than mountains and plateaus because these areas are suitable for farming, manufacturing, and service activities. The Ganga Plains are the most densely populated area in the world, while mountains like the Andes, Alps, and Himalayas are sparsely populated.</p> Signup and view all the answers

<p>The birth rate is the number of births per 1,000 people, and the death rate is the number of deaths per 1,000 people. Birth and death are the natural causes of population change.</p> Signup and view all the answers

<p>When the birth rate is more than the death rate, it means that the population is increasing and vice-versa. The difference between the birth rate and the death rate of a country is called the natural growth rate.</p> Signup and view all the answers

<p>Population composition refers to the structure of the population. The composition of the population helps us know how many are males or females, which age group they belong to, how educated they are, what type of occupations they are employed in and what their income levels and health conditions are. An interesting way of studying the population composition of a country is by looking at the population pyramid, also called an age-sex pyramid.</p> Signup and view all the answers

<p>The graphical representation used to study the composition of a country's population is called the population pyramid. It shows the total population divided into various age groups, the percentage of the total population subdivided into males and females and the number of dependents in a country. When the population of a country has high birth and death rates, the population pyramid is broad at the base and narrow towards the top.</p> Signup and view all the answers
