Government finance statistics
Main source
The IMF data portal is a starting point for government finance and other economic datasets. Search for Government Finance Statistics and read the dataset metadata before extracting observations.
Before comparing observations
Central government and general government are different institutional boundaries. Record cash versus accrual basis, consolidation, currency and whether values are levels or shares of GDP.
Use the publisher's documented download or API options. Preserve the dataset identifier, selected dimensions, access date and source licence with an extract.
