A generalized presentation of sex ratio distribution for a region gives us only partial information. The present study analyses sex ratio for Birbhum and Murshidabad districts of West Bengal, at three levels i.e. District, Block and Village level in different categories i.e. Child sex ratio, Adult sex ratio or Scheduled caste and scheduled tribe sex ratio, using PCA census 2011. When studied on a micro-level say, village and block level, we get to know the real problem area, which particular village or block has low sex ratio in a specific category. So that the governing authorities know specific problem area in a large region, it leads to efficient planning; resources can be diverted to a particular village or block to target a particular type of low sex ratio. Within a district, zones of low or high sex ratios can also be visualized which is related with characteristics of demography in that zone, e.g. high or low Scheduled caste or tribe population. Block level analysis is showed with the help of bar graphs and Village level analysis is showed with the help of ArcGIS maps. The maps make it easier to compare between Birbhum and Murshidabad districts.
