World aggregate time series (sum or mean across countries)
Returns a Sugra-computed world aggregate across all Penn World Table countries for the requested variable subset. Pick aggregation=sum for level variables that add meaningfully across countries (rgdpo, rgdpe, pop, emp, cn, ccon), or aggregation=mean for unitless indices, shares, and price levels (hc, ctfp, cwtfp, labsh, pl_gdpo, csh_*). The Penn World Table upstream dataset does not ship a World row; this endpoint derives one at request time. Null values in the panel are skipped from the aggregate. Not every country contributes in every year, so the mix of contributing countries varies by year - keep this in mind for long-run world totals.
