India Village-Level Geospatial Socio-Economic Data Set: 1991, 2001

The India Village-Level Geospatial Socio-Economic Data Set: 1991, 2001 is a compilation of the finest level of administrative boundaries in India (village/town-level) and over 200 socio-economic variables collected during the Indian Census in 1991 and 2001. This data set was developed by digitizing village/town level boundaries from the official analog maps published by the Survey of India for 2001. This data set also utilized tabular data for 1991 and 2001 from the Primary Census Abstract (PCA) and Village Directory (VD) data series of the Indian census. The data are in UTM 44N projection and are distributed primarily as shapefiles. Separate files are provided for each of the 28 states (number of states during 1991 and 2001 census) and combined Union Territories for 1991 and 2001.

《印度村级行政边界地理社会经济数据集：1991年，2001年》系对印度最精细的行政边界（村/镇级）及在1991年和2001年印度人口普查期间收集的超过200个社会经济变量的汇编。该数据集由印度测绘局发布的2001年官方模拟地图中的村/镇级边界数字化而成。此外，数据集还利用了1991年和2001年的初级普查摘要（PCA）和村目录（VD）数据系列中的表格数据。数据采用UTM 44N投影，并以形状文件为主要分发格式。针对1991年和2001年的普查，分别提供了28个州（普查时的州份数量）及联合区的独立文件。
