'shrinking-demographic' originates from the combination of 'shrink' and 'demographic', where 'shrink' meant 'to become smaller' and 'demographic' referred to 'a specific segment of the population'.

The term 'shrinking-demographic' evolved from the need to describe population trends in sociology and economics.

Initially, it meant 'a group of people becoming smaller in number', and this meaning has largely remained the same in modern usage.
