- FX rates are April 2026 snapshots. Day-to-day FX volatility affects USD-equivalent conversions.
- Cost-of-living data is Numbeo 2026, crowd-sourced and urban- skewed. Rural and non-capital-city costs can differ materially.
- Does not include employer-provided benefits (health insurance, retirement match, paid leave, which vary dramatically between these two countries).
