Data Market is a website that provides easy access to 13k data sets, 100 million time series, and 600 million facts! DataMarket is a type of "one stop shopping" to obtain data for countries ranging from Afghanistan to Zimbabwe and issue ranging from agriculture to youth.
Since I work in the Middle East, and with the recent "Arab Spring" I decided to graph internet users in the countries of Egypt, Jordan, Lebanon, Morocco, Tunisia, Palestine and Yemen. The graph below was produced and DataMarket provides various formats to export the data and graphs.
As the graph illustrates, since 2001 there was a dramatic increase in the number of internet users in Egypt, followed by Morocco and Tunisia with much lower increases in internet users were in Lebanon, Jordan and no real increase in Libya or Yemen.
So, give DataMarket a try and see if it can help you quickly get the data you need and illustrate it.
