Why country rank and global rank are different
Two different reference distributions can give valid but very different positions.

Two reference populations
A national rank describes position in one country’s adult income distribution. A global rank describes the purchasing-power equivalent’s position in the world distribution. A high worldwide position is not automatically an error because daily life feels expensive locally. The statistical question and the personal-budget question are different.
The national-median experiment
Imagine an amount at country A’s median. Its national top percentage is approximately 50%. Convert that median into USD PPP and locate it on the world curve. There is no reason it must also land at the world median. The national and world distributions can have different levels and shapes.
Inspect instead of guessing
Country pages show published thresholds and the world position of the national median using the stored factor. The global explorer shows the separate world thresholds. Together these views make the difference inspectable without changing sources or silently substituting a salary definition.
Compare like with like
Percentiles do not deduct rent, debts or taxes. The raise tool can model an inflation assumption but cannot update historical distributions or predict a future rank. Save ranks optionally in the main calculator and compare later results only with attention to country and dataset. Use country comparison when the question concerns a different location rather than change over time.
