Child mortality fell. Then progress stalled.

A child's odds of reaching five still depend on where they are born.

A boy in Norway and a boy in Chad born at the same moment are born a century apart in survival terms.

Key Takeaways
  • Child mortality has been halved since 2000 and is the lowest it's ever been
  • But progress has slowed significantly since 2015
  • There's a strong correlation between income levels and child mortality
  • Solutions exist, but aren't always accessible to those that need them most

“ONE Data is exactly the kind of infrastructure the development sector needs. It transforms the nightmare of fragmented financing data into data that is interoperable and accessible, and can drive real change.”

Prem Ramaswami, Data Commons Product Manager, Google

“If you can't measure it, you can't manage it. ONE data enables an evidence-based approach. They turn complex issues into intelligible and digestible data sets, allowing for an informed debate and decisive action.”

Omar Ben Yedder, Group Publisher, African Business
