Latin America and Caribbean Population Distribution Database from UNEP/GRID-Sioux Falls

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.

This documentation describes the Latin American Population Database, a
collaborative effort between the International Center for Tropical
Agriculture (CIAT), the United Nations Environment Program (UNEP-GRID,
Sioux Falls) and the World Resources Institute (WRI). This work is
intended to provide a population database that compliments previous
work carried out for Asia and Africa. This data set is more detailed
than the Africa and Asia data sets. Population estimates for 1960,
1970, 1980, 1990 and 2000 are also provided. The work discussed in the
following paragraphs is also related to NCGIA activities to produce a
global database of subnational population estimates (Tobler et
al. 1995), and an improved database for the Asian continent (Deichmann
1996a).

拉丁美洲人口数据库（Latin America Population Database）是持续完善全球空间参考人口统计数据储备工作的组成部分。此类数据库可广泛应用于多个领域，包括战略级农业研究，以及全球变化人文维度的分析相关工作。

本说明文档旨在介绍拉丁美洲人口数据库，该数据库由国际热带农业中心（International Center for Tropical Agriculture, CIAT）、联合国环境规划署苏福尔斯网格项目（United Nations Environment Program, UNEP-GRID, Sioux Falls）以及世界资源研究所（World Resources Institute, WRI）联合开发。本项目旨在构建一套人口数据库，以补充此前针对亚洲和非洲开展的相关工作。本数据集相较于亚洲、非洲数据集更为精细详实，同时提供了1960年、1970年、1980年、1990年及2000年的人口估算数据。下文所述的相关工作，还与国家地理信息与分析中心（NCGIA）开展的两项任务相关：一是构建全球次国家人口估算数据库（Tobler等，1995），二是优化亚洲大陆人口数据库（Deichmann，1996a）。
