Country comparisons using graphs, maps. Huge database of world statistics. Reference site contains country statistics, maps, flags, graphs and pie charts.
Encyclopeadia, country statistics and other such useful stuff. Haven't had any problems with this site.
A fantastic treasure trove of information.
Very awesome statistic data and records

NationMaster is really amazing research resource. You can graphically compare countries of the world on any parameter – country size, population, economy, health, mortality, religion, patriotism, funds pledged for the recent tsunami disaster – just about anything under the sun. A one stop shop for all my needs. I sincerely recommend it to all students doing serious research on countries.
