Most passport rankings give you a single number. That's useful, but incomplete. Two passports with the same destination count can open very different parts of the world.
HabiBubble measures passport strength through three independent lenses:
- Mobility — How many countries you can visit without a pre-arranged visa.
- GDP reach — How much of the world's economy your passport unlocks.
- Heritage — How many UNESCO World Heritage sites are accessible to you.
We also measure how smooth entry is — visa-free versus an e-visa you arrange in advance — but show it as the visa-type breakdown on each passport, not as a separate rank, because it closely tracks mobility.
Why three indices instead of one
A single score hides important trade-offs. A passport might rank #30 on destination count but top 10 on GDP reach because it opens the US, EU, and East Asia. Another might have excellent mobility but reach a much smaller slice of the world's economy.
By showing all three, you see which dimension matters to you:
- Frequent business traveller? GDP reach matters most.
- Culture-focused traveller? Heritage is your index.
- Backpacker? Raw mobility is what counts.
How we show it
Mobility is the headline rank — the other two appear alongside it. Each has its own rank, so nothing is hidden or averaged away.
We chose transparency over simplicity. Three honest numbers beat one misleading average.
