Looking for statistics? Try Statista!
Statista has lots of industry, market, and economic statistics from major countries around the world, plus “dossiers” of related data on a variety of topics. It’s very easy to use, provides details about and links to the original sources of the data, provides proper citations, and allows for easy exporting of graphs and charts.
Statista tends not to have deep historical data series, though, so if that’s what you need, try Data-Planet Statistical Datasets. It’s also easy to use, provides detailed information about the data sources, provides citations, lets you create links to specific datasets, easily lets the user change parameters like country, year, or actual dataset, and is global in scope.
