John Grount initiated the study of demography based on his work 'Natural and Political Observation Made upon the Bills of Mortality' in 1662. Therefore, he was considered as the Father of Demography. However the word 'demography' was first coined by Achille Guillard in his book Comparative Demography published in 1855.
The word demography is derived from two Greek words 'demos' and 'graphien'. Demos means people whereas graphien means to study. So, in simple words we can say that demography is the study of human population. Demography is the systematic and scientific study of the human population primarily with respect to size, structure, distribution and change (development).
Population change results from the interaction of demographic components, viz, birth, death and migration. Therefore, demography deals with the detailed study of the three components. With the measurement of such components, various aspects of the population are analyzed and interpreted. It helps to plan and implement various development activities.
The word 'demography' is derived from two Greek words 'demos' meaning people and 'graphy' meaning science or studies. So, demography refers to the study of human the population. It makes scientific and statistical study of the population with respect to its size. The study of human population is very important. It has developed as a separate discipline of modern time. It gives us information and idea about the population situation and its trend. Problems of its management and solution. So, it is essential in planning and developmental activities of every human society.
Demography is the mathematical and scientific study of the size, structure, distribution and other important aspects of the population. The process of finding out the number and rates of these three factors is known as population measures. The status of the change in the population can be known through the measure of birth, death and migration rate. It is useful in population studies for the following reason:
