The Census Organization has published Census Atlas volumes during 1961, 1971 and 1981. The Census Centenary Atlas was published during 1973 as a special project. Besides the Atlases, maps of districts, tahsifs, community developm~nt blocks and other administrative units showing basic amenities, population and infrastructure are being published regularly in each Census. The idea of the Atlas was conceived for the first time at the 1961 Census and a special programme of the Census Atlas mapping was organized. In this programme, Census Atlases of States and Union Territories were brought out. This publication programme has been much appreciated by data users and academicians alike. The present volume is part of jhe Census Atlas series of states and union territories. The list of tiUes of the maps has been generated on the basis of the tabulation plan for the 1991 Census. One hundred and twenty five themes were identified. The number of maps includDd in the Atlas Volumes varies from state to state to some extent depending upon the availability of data. The maps in the Atlas volumes portray different themes. There are maps of administrative and physical aspects reflecting the general characteristics of the State followed by maps on demographic, economic and socia-cultural aspects consisting of distribution, density and growth of population, age and sex, urban trends, industrial categories, migration, literacy, religion, scheduled castes and scheduled tribes, education and housing. The choropleth technique has been adopted for the presentation of data in the maps. However, multi-cartographic techniques have also been used frequently depending upon the suitability and requirement of the maps as well as data. The work on the Atlas programme was undertaken by the officers and staff of the Map Division in the Registrar General's office and the Map Units of the Directorates of Census Operations. A list of those who have contributed to the completion of the work is given separately and all of them deserve appreciation. I hope the Census Atlas volumes will be found useful by scholars, planners, administrators and other data users. New Deihl Dr. M.
