More than numbers: Census data provide unparalleled insight into the world’s demographic, social, and economic development
GCA provides a single platform experience to explore the world’s census publications: all countries and regions, the complete depth of published census materials, including original census publications in e-book form, as well as modern tabular data in Excel format and GIS files for advanced users. This truly global collection contains all available primary source and official census publications associated with a given census. GCA currently contains millions of pages of publications and billions of data points in GIS format, with more content continually added as new censuses are produced across the globe. Users can browse historical publications as full-image, full-text e-books (in any language), download tabular data in Excel format (for born-digital publications), and download GIS data (e.g., shape files of administrative boundaries)—all from a unified discovery interface. GCA simplifies access and increases the discoverability of demographic data from the world’s census publications. Research and analysis is improved with e-books that are fully machine-searchable, with full-image, cover-to cover browsing of original census publications (as well as important supplementary primary source materials, such as original census questionnaires and ephemera), plus the ability to download a variety of GIS and tabular data files to complement existing modern census collections.
