## In plain language

A baby who is born small. The exact weight threshold depends on the source and is not recorded here yet.

## Technical summary

Birth weight below a defined threshold. This atlas does not yet record the general definition, so each study's birth-weight band (for example 1.0 to under 1.8 kg) is kept with that study's context.
