Working note: percent of GDP and currency per person answer different questions. Preserve indicator code, year, unit and provider. Current and capital spending also have different scopes.
Synthetic example: 10% of 100 is 10, while 5% of 1,000 is 50. A larger spending share does not establish a larger total or a larger per-person amount.
Open for verification: propose a compatible pair of public indicators for a particular comparison. State the aggregation method; provider aggregates need not be identical. Keep missing years explicit.
