3. Integration of Census Data with GIS for Analysis of Population Characteristics

GIS is very well used to integrate the census data for population characteristics. Analysis of population characteristics plays an important role in population geography. In this chapter various aspect of population characteristics like population growth, distribution, density, sex ratio, literacy, occupational structure of peoples in Varanasi are discussed. Population characteristics are relatively vital because it defines the economic and cultural condition as well as characteristics of the area, concerned. The decennial growth rate of Varanasi district had been very high during the last three decades. This has resulted in the pressure of population on land. Growth rate of male-female population during last 3–4 decades (from 1971 to 2001) in Varanasi district has been increased more than double. As per the census 2001, the current sex ratio (female population per 1000 male) in Varanasi city is 876, which is lower than the state urban average of 885 and national urban average of 901. Such rural-urban differentials in sex-ratio are the product of sex selective migration from rural areas to urban areas. Occupational composition is an important index to through light upon the economic dynamic of health and vigor of a region. The growth in population is also likely to pressure already stressed public transport and will have effect on health services, hence planned efforts are required to direct the growth of the district both rural and urban area in right direction.
