PWT Releases

Penn World Table


Welcome to the website of the Penn World Table (PWT)

PWT is a database with information on relative levels of income, output, inputs and productivity, with country and period coverage depending on the release. On these pages you find access to several releases of this data set, as well as documentation. For news about PWT check out our blog. To stay informed about new releases, follow us on Twitter @PennWorldTable.

If you are new to PWT, the User Guide is a good starting point as is this Vox column. In the menu on the left you will find an overview of the available PWT releases. For questions not covered in the documentation, please contact
