UN Human Development Index [Data]

The UN Human Development Index measures the life expectancy, educational attainment, and income of most nations. "The breakthrough for the HDI was the creation of a single statistic which was to serve as a frame of reference for both social and economic development."

The site is a great way to have students look up differences between nations and regions on three major indicators. The data are also easy to sort on the spot- and so you could use this in class to start a discussion on global inequality.

The site does a great job explaining how each data point was calculated, so this would also be a nice tool to use if you wanted to talk about measuring and operationalizing concepts.
