Introduction

Welcome to the Archive of Census Related Products (ARCP), one of several efforts to support the Population, Land Use, and Emissions (PLUE) Data Project at CIESIN. This archive is a collection of georeferenced data files containing census information that spans the United States and its territories. This coverage will expand to include Mexico and Canada, establishing a North American repository for population, land use, and emissions data and integrated data products. These data files are value-added products derived from the original 1990 census files compiled by the U.S. Bureau of the Census.
