For your edification, but also to help you with your assignments, papers, and blogs, here are some data sources that will allow you to compare levels of development and poverty across the globe. The United Nations Development Programme’s Human Development Report is an excellent source of information on indicators related to development. Click here if you would like to look up data and/or statistics. You can search for statistics by country, indicator, or table.
Another excellent data source is the World Bank Development Indicators collected by the World Bank. This link provides access to the Education, Gender, Health & Nutrition & Population, and Poverty databases as well as Country Statistical Information, and Development Gateway Data and Statistics.
Finally, the United Nations maintains a statistical division, whose website can be found here, and which collects a wide range of data from social and demographic statistics, through economic, environmental and energy statistics, to statistics related to Millennium goal indicators.
