This project follows as closely as possible the design and methodology of previously-developed Asian and African databases (Deichmann 1994, Deichmann 1996a). The database has been updated since previous versions were published on the United Nations Environment Program's spatial data clearinghouse (UNEP 2000) and on CIAT?s web site. The new maps include new information from the 2000 census round for 16 countries. We improved the spatial resolution of the new map by collecting data at more detailed administrative levels for several countries, increasing the number of administrative units substantially compared to our previous release. We include information on the sources of the population and administrative boundary data, procedures for compiling the data, and some indicators of the quality of the data set. Documentation of the methods to create the maps was derived from the earlier work for Africa and Asia. The raster population surfaces are based on a data set of over 18,300 administrative units and 10,700 populated places. Population growth rates were use to project population totals acquired at the date of each country census back to 1960 and forward to 2000. This documentation also includes appendices with information on data resolution and quality, data sources for population and administrative boundary information. The main difference between this verison and previous efforts is that it includes a mechanism that incorporates new census and administrative data as they become available, and which ensures consistency with other sources and provides easy access to the data. The Latin America 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. The population figures attached to the GIS database represent estimated totals for the standardized years 1960, 70, 80, 90 and 2000. Data sources vary by country. In general we attempted to obtain population data from each census that has been carried out at the geographical level for which boundary data were available. Where official population estimates or projections were available from the national statistical office, these were used as well. In order to provide an indication of population dynamics and to maximize comparability across national boundaries, population estimates were produced for 1960, 70, 80, 90 and 2000.Data format - GeoTIFFCell Size 0.042 degrees Data Type IntegerNumber of Rows 2208 Number of Columns 2088 Xmin = -119.000 Xmax = -32.000 Ymin = -58.000 Ymax = 34.000 Projection GEOGRAPHICUnits DD Spheroid CLARKE1866 1960 2000 publication date Complete As needed -119 -32 34 -58 none population density population demography none Latin America Caribbean South America Central America none 1960 - 2000 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. 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.
