PWT version 9.0 is a database with information on relative levels of income, output, input and productivity, covering 182 countries between 1950 and 2014. Access to the data is provided below:
If you are new to PWT, please consult the User Guide to PWT 9 for further information and a guide to the available documentation. This Vox column is a good starting point as well. If you are an experienced PWT user, please consult What is new in PWT 9.0.

Selective data access
|Query||Variable Name and Use||Example|
|RGDPNA||Real GDP using national-accounts growth rates, for studies comparing (output-based) growth rates across countries||Dependent variable in (cross-country) growth regressions|
|CGDPe||Expenditure-side real GDP at current PPPs, to compare relative living standards across countries at a single point in time||Initial level in growth regressions requiring relative living standards|
|CGDPo||Output-side real GDP at current PPPs, to compare relative productive capacity across countries at a single point in time||Initial level in growth regressions requiring productive capacity or productivity|
|RGDPe||Expenditure-side real GDP at chained PPPs, to compare relative living standards across countries and over time||Living standards of China today compared to the US at some point in the past|
|RGDPo||Output-side real GDP at chained PPPs, to compare relative productive capacity across countries and over time||Productive capacity of China today compared to the US at some point in the past|
|DA||Development accounting, the sources of differences in living standards at a point in time||Is the US richer because of more inputs, higher productivity, or both?|
|GA||Growth accounting, the sources of economic growth over time||Analysis of the sources of economic growth over time|
Notes: Real GDP variables are in (millions) of US dollars, not in per-capita terms. A population variable (acronym pop), which can be used to convert GDP into per-capita terms, is included in the relevant queries.
