Population functioning is operationalised through the measures used in the WHO Model Disability Survey (MDS). The MDS is a population survey that provides detailed and nuanced information on how people with and without disabilities conduct their lives and the difficulties they encounter, regardless of any underlying health condition or impairment. Other national population surveys that measure functioning may also be used.

Functioning of population as measured by the MDS, across the spectrum of functioning levels.

This is a continuous variable measure. The target population is the national population with and without disability.
