The LandScan Global Population Databases, developed at the Department of Energy's Oak Ridge National Laboratory, represent resolution global population distribution databases available. This is a geographically based, population distribution model.
LandScan is a global population database that shows geographical distribution of population at one-kilometer resolution over an average 24 hour period.
The LandScan algorithm uses spatial data and imagery analysis technologies and the most up-to-date census data within an administrative boundary. Accurate administrative boundaries are an integral part of the LandScan population distribution modeling process. These population distribution models are tailored to match the data conditions and geographical nature of each individual country and region.
Most national censuses count populations by measuring where people sleep (or reside) rather than where they work or travel. LandScan integrates daytime movements and collective travel habits into a single measure to produce a better representation of where people are located during an average day.
With improvements added this year, high-resolution imagery sources were used extensively for validation to refine urban areas, land cover data, and thousands of smaller villages and populated places.

Designed to "connect the data to the research it informs," Data Citation Index captures all available metadata for the data repositories indexed. Currently, 69 repositories and over 1.75 million records in the Life Sciences, Social Sciences, Physical Sciences, and Arts & Humanities are indexed. Includes citations to publications reporting research which utlitizes the data.
Provides access to statistical information produced by U.S. Federal agencies, private companies, and intergovernmental organizations. Create maps and reports from data you select from over 640 datasets. Subjects include health, crime, population, finance, industry, and marketing.
Data is available for the world as a whole or for selected countries. Data for the U.S. are shown by state, often by county, sometimesby census tract and zip code. Time series data may go back several decades.
Data sources include the U.S. government, the World Bank, Dow Jones, Dun & Bradstreet, Mergent, and Standard & Poors.
The University Library has Dataets Basic Subscription, which does not include EASI Market Planner, IMF data or data from the U-M China Data Center. U-M China Data Center is available from China Data Online.
Social Explorer provides easy access to demographic information about the United States, from 1790 to present. Create maps and reports based on decennial censuses of 1940 to 2000.
SimplyMap is a web-based mapping application that allows you to create thematic maps and reports using demographic, business and marketing data. Data can be downloaded for use with other software such as Excel and GIS.
The GEOnet Names Server (GNS) provides access to the National Imagery and Mapping Agency's (formerly Defense Mapping Agency) database of foreign geographic feature names.
