As anyone who does comparative social science research knows, finding reliable data sources in one place can be a difficult task. Fortunately, there is the United Nations Economic Commission for Europe (UNECE). On the UNECE website, visitors can find data related to macroeconomics, gender, and transport for all of the countries in Europe. First time visitors may want to start by reading the "About this database" overview, and then taking a look at the summary statistics for the past several years in the "Facts and Figures" area. Moving on, visitors can view tables and statistics that relate to industrial production, price indices, forest resources, and biological diversity. Visitors to the site can also register for free to create their own comparative data tables and save them for future use and consultation. Also, visitors can view the UNECE document library and look over a list of related links.
