subpopulations
Groups within groups
Subpopulations are distinct groups within a larger population, identified by shared characteristics.
In biology, a subpopulation might share genetic traits or geographic isolation: The island subpopulation developed resistance to the disease.
In statistics and public health, subpopulations are segments analyzed separately: The vaccine showed different efficacy across subpopulations defined by age.
