Age Class

A term defined in ecology as a group of individuals of the same age within a species. A similar “taxonomic” device has evolved in medicine, where large blocks of patients are divided by age and treated by the appropriate specialist—neonatologist, pediatrician, and adolescent medicine specialist in the beginning of life, and geriatrician at the end of life.
