Abstract:
This project (which has been carried out as a cooperative activity between NCGIA, CGIAR and UNEP/GRID between Oct. 1995 and present) has pooled available data sets, many of which had been assembled for the global demography project. All data were checked, international boundaries and coastlines were replaced with a standard template, the attribute database was redesigned, and new, more reliable population estimates for subnational units were produced for all countries. From the resulting data sets, raster surfaces representing population distribution and population density were created in collaboration between NCGIA and GRID-Geneva.
Purpose:
The Asian administrative boundaries and population database is part of an ongoing effort to improve global, spatially referenced demographic data holdings. Such databases are useful for a variety of applications including strategic-level agricultural research and applications in the analysis of the human dimensions of global change.
Supplemental_Information:
With few exceptions, we used official census figures or official estimates 
which were taken from national publications (census reports or
statistical yearbooks) or from secondary data sources (yearbooks and 
gazetteers). 
In order to maximize comparability across national boundaries, all 
district-level population figures were projected to 1995.

Access_Constraints:
The GRID database is maintained for the purpose of assisting individual nations and the international community in making sound decisions related to resource management and environmental planning, and where applicable providing data for scientific studies. In general, requests for data from the archive will be filled according to data availability, GRID workload and the nature of the data set being requested. Requests will be queued with priority given to requests related to joint activities with UNEP programme areas. UN organizations, intergovernmental organizations, scientific and academic organizations, non-governmental organizations are all eligible to request data from the GRID archive. Requests from eligible organizations for data with unrestricted access rating will normally be filled without further clearance. Requests for data with a source approval rating will be referred to the relevant authority for clearance, and in some cases, the requestor will be advised to seek the data from the source. Data sets with an in-house rating will not be distributed; however, information about such data sets, including the distributor's name, will be sent to eligible organizations on request. Data requests from private commercial firms and private individuals will not be filled. Exceptional cases in which the intended use of the data would be of direct benefit to the United Nations or member states will be considered on a case-by-case basis by the GRID Director, in consultation with the UNEP Assistant Executive Director-Programme.
Use_Constraints:
Users of datasets supplied through GRID are requested to incorporate in output products and reports acknowledgments to the originator of the data and to the fact that they were acquired through GRID. Appropriate wording may be "UNESCO(1987) through GRID".

Corresponding (W. Asia) Population Density Map [GRID ASCII, BIL]
Distribution_Liability:
The Asian administrative boundaries and population database was compiled from a large number of heterogeneous sources. The objective was to compile a comprehensive database from existing data in a fairly short time period that is suitable for regional or continental scale applications. The resources available did not allow for in-country data collection or collaboration with national census bureaus. With few exceptions, the data do not originate from the countries, and none of the input boundary data have been officially checked or endorsed by the national statistical agencies.
