Prasanta Chandra Mahalanobis: Zitate auf Englisch

“Population in India is widely differentiated in ethnic composition, geographical and climatic conditions, social and cultural stratiﬁcation, as well as by differences in economic status. Differential fertility therefore assumes a far more complex picture in India than anywhere in the world. Ethnic. geographical. socio-cultural and economic dilferences give a four-fold patterning with many complicated interactions. It is essential therefore to study different population groups separately.”

Quote, Professor P.C. Mahalanobis and the Development of Population Statistics in lndia

“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.”

Quote, Professor P.C. Mahalanobis and the Development of Population Statistics in lndia

“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 tatistical 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.”

Quote, Professor P.C. Mahalanobis and the Development of Population Statistics in lndia

“It would be, however, a fatal mistake to establish an expensive system of education on the model of the advanced countries which would have little relevance to local needs and would be beyond the means of the national economy. It is necessary to evolve a system, through experimentation and trial and success, which would be within the means of the national economy.”

Quote, Prasanta Chandra Mahalanobis in Vigyanprasar

“The transformation of the advanced countries to their present stage has been brought about by the acceptance of a scientiﬁc and rational view of life and nature. The scientiﬁc view has already permeated in a large measure the administrative organizations of the advanced countries. The scientiﬁc revolution, the social revolution and the industrial revolution are three aspects of the modernization of every society; these three aspects may be distinguished but cannot be separated. The rate of economic growth in every country is determined both directly and indirectly by the rate of progress of science and technology; directly through the utilization of the results of research and development, and indirectly through institutional changes brought about by the increasing inﬂuence of the scientiﬁc out-look and tradition.”

“The spirit and outlook of 'Sankhya' will be universal, but its form and content must necessarily be, to some extent, regional. We shall keep the special needs of India in view without, however, restricting the scope of the journal in any way. We shall naturally devote closer attention to the collection and analysis of data relating to India, but we shall try to study all Indian questions in relation to world problems…. The study of modern statistical methods in its infancy in our country, and we do not expect to be able to achieve immediate results. We shall be satisfied if we can help by our humble efforts to lay the foundations for future work.”

“some evidence is available to indicate that, in India, an increase in the income of the poorer people leads to an increase in the size of the family; and also that this tapers off after a certain critical level of income is attained, and is followed by a reduction in the size of the family at higher levels of living When a sufﬁcient number of people reach the critical income, there would be a gradual decrease in the average birth rate with further increase in income.”

“India has a medieval and authoritarian structure of society and the tradition of science is not yet strong. The power of government officials is increasing as an inescapable result of the pervasive anthoritarian character of lndian society.”

Quote, Professor P.C. Mahalanobis and the Development of Population Statistics in lndia

“We believe that the idea underlying this integral concept of statistics finds adequate expression in the ancient Indian work Sankhya in Sanskrit the usual meaning is ‘number‘, but the original root meaning was ‘determinate knowledge’ in the Atharva Veda a derivative from Sankhyata occurs both in the sense of ‘well-known‘ as well as ‘numbered’. The lexicons give both meanings. Amarakosa gives Sankhya – vicarana (deliberation, analysis) as well as ‘number’; also Sankhyavan”

Quote

“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.”

Tagore in "Prasanta Chandra Mahalanobis in Vigyanprasar".

“Everybody knows him as the founder of the Indian Statistical Institute, the architect of the Second Five Year Plan, a close associate of Rabindranath Tagore and as one who had richly contributed to the social, cultural and intellectual life in Bengal. All those in the statistical profession were aware of his deep contributions to statistical theory, his efforts in providing a sound database to the Indian economy, and the part he played in placing India not far from the centre of the statistical map of the world. Those who have been closely associated with him have witnessed the indomitable courage and tenacity in fighting opposition for a good cause and clearing obstacles for propagating right principles.”
