Abstract: The China Administrative Regions GIS Data: 1:1M, County Level, 1 July 1990 is composed of boundary files covering the administrative regions of China. The data are at a scale of one to one million (1:1M) for national, provincial, regional, and county levels. The temporal coverage represents the status of China administrative regions as of 1 July 1990. In addition to the administrative regions dataset that were developed for 30 December 1990, the SEDAC China project developed the China administrative regions GIS data that are valid for 1 July 1990. This dataset was developed to correspond with the region names and associated codes that are used in the 1990 China census. The differences in the two datasets consist of the conversion of County and District regions to Cities: counties to cities and districts (QU) to cities. These files are organized by national and individual province levels. The national level covers all of the administrative regions of China, which includes two files: ( coverage of all provincial boundaries), and (coverage of all county boundaries). The data is stored in ARC/INFOŽ export format. The data at the province level separate administrative regions into individual provinces and autonomous regions. The county boundaries of 31 provinces and regions are identified in 31 files named t**9071.e00. The ** represents the first two numbers of the GB-Code (GuoBiao Code or the National Standard Code of P.R. China) for the provinces. These data files are in Arc/Info export format.
