l have liked your article very much. The way you have narrated the history of my humanism in an evolutionary perspective has made this aspect of mine… - Prasanta Chandra Mahalanobis

Because demography is concerned with human affairs and human populatlons it is possible, in principle, to consider demography as a sub-field of many other subjects. It provided the scope of any particular subject-field like anthropology, genetics, ecology, economics, sociology, etc., and is defined in a sufficiently comprehensive manner. While not denying the possibility of considering demography as a sub-field of one or another subject, at least for certain special purposes, it is suggested that demography should be logically viewed as the totality of convergent and inter-related factors and topics which (although these could be, spearately, the concern of many difl'erent subjects like genetics and anthropology, sociology, education, psychology. economics, social and political affairs etc.) jointly, together with their mutual inter-actions, form the determinants as well as the consequences of growth (or decline), changes in composition, territorial movements, and social mobility of population in different geographical regions or in the world as a whole, at any given period of time, or over difl'erent periods of time. Such a view would supply an aggregative, inter-related, and mutually interacting system of all those factors which have any influence over, or are influenced by, demographic or population changes over space and time.

In the absence of social awareness and appreciation of the scientific objectivity among sufficiently large number of civil servants or political leaders,the need of validity has not yet been accepted in the official statistical system in India. Ofcial statistics in India is treated as an integral part of the dministrative system which is regulated by the principle of authority. Approval of statistical estimates at a high level of authority is accepted as a bstitnte for validity in many ases there is continuing opposition to independent cross-hccks for the validity of the data. Officials have the feeling that two independent estimates, which might differ would be confusing and, in fact unthinkable; therefore independent cross-checks in statistics should be eliminated.

Without the progress of equality and improvement in the level of living at least beyond the poverty line, for one quarter of the population of the world who live in South Asia, there would be grave repercussions on the rest of the world. The problem of the underdeveloped country is, in one sense, of greater concern to the advanced countries because international rivalries and tensions arise from the desire to establish spheres of influence over underdeveloped areas. The very existence of underdeveloped regions would he therefore a continuing threat to world security, and world peace. A quick transformation of the underdeveloped countries into industrialized economies would reduce the sphere of conflicting interests; and hence decrease the tension between East and West.
