From the U.S. Census:
The U.S. Census Bureau recently updated its popular World Population Clock Web tool with features and information for 228 countries. In addition to featuring the 10 most populous countries, already available in the clock, it now includes country profiles with trade and population statistics, such as total population, population per square kilometer, and goods exported from and imported to the United States. Additional features include graphics on population projections and top exported goods by U.S. state or territory.
Along with the updated clock, another new tool, the International Map Viewer, is now available. This tool shows the four most commonly requested demographic measures for foreign countries using statistics from the International Data Base — total population, growth rate percent, life expectancy at birth and infant mortality rate — by clicking on a world map.
