To facilitate data processing, I have put together a collection of 36087 variables from the largest cross-country databases. Every variable is stored as a separate file, which can easily be imported from the command prompt of your statistical software. Some basic code for Stata is available here. A variable list is available on this site as a searchable MySQL database.
There are two versions of the database. Visitors outside Uppsala University, like yourself, can only access data that otherwise could be obtained for free from the original sources. If you believe you should have full access to the database, please send me an e-mail and be sure to include your IP address (188.8.131.52). For legal reasons I don't provide data that you cannot access in other ways.
Use the search form in the right column to find the variables you want.
