This game compares under-five mortality rate across countries.

• The figure estimates how many children die before age five per 1,000 live births.
• It bundles sanitation, nutrition, vaccination, transport, conflict, and primary care into one brutal denominator.
• Life expectancy can sound gradual. Under-five mortality is where state capacity gets much harder to romanticize.

Nothing clarifies a system faster than how often it fails before kindergarten.
