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.
