Penn World Table (PWT)

rug.nl/ggdc/productivity/pwt

El conjunto de datos de referencia para comparar PIB y productividad entre países desde 1950. Incluye también el PDF de documentación, que explica qué significa cada variable.

PWT is the reference economists reach for when comparing GDP, productivity, and price levels across countries, built specifically to make cross-country comparisons valid rather than just aggregating each country's own GDP figures. A notebook comparing economic growth across nations over decades should pull both the data file and the documentation, since the variable definitions matter for interpreting the numbers correctly. It's not updated in real time — releases come on an irregular schedule, so recent years may lag behind sources like the IMF or World Bank.
