Jalpaiguri District Migration History Between 1872-2011

In social science research studies, human migration is an important aspect, which is an interdisciplinary research problem. Presently, History researchers are also attracted to it. In social science migration research problems such as when do the people move from one place to another, who moves, why do they move, what are the historical events associated with the movements, and what are the impacts when they live there are mainly studied herein. It is well known that historical data sets are not accurate as collected from scientific studies, or physical measurements. It is necessary to perform history research with efficient robust estimated historical data that can only be obtained from the derived probabilistic model based on the raw available data. The present paper studies migration problems of Jalpaiguri District, West Bengal, India from 1872 to 2011 using census data, based on parametric and nonparametric population growth trend models. It not only derives the efficient population growth data estimates during this period, but also concentrates on the above stated migration related social science research problems, from the derived parametric and nonparametric probabilistic models. It is noted herein that parametric model provides better estimates than nonparametric probabilistic models.
