THE COUNTRYWHY METHOD

02Find the primary record

Budget tables, regulatory filings, national statistics and official transcripts.

03Separate facts and explanations

Disclose what is measurable and which interpretations remain disputed.

04Return when the data changes

Update the analysis when a budget passes, a rule changes or new figures arrive.
