'demographic' originates from Greek, specifically the word 'dēmos,' meaning 'people,' and 'graphia,' meaning 'writing or description.' 'Growing' comes from Old English 'grōwan,' meaning 'to grow or flourish.'

'Demographic' evolved from the French word 'démographique,' while 'growing' remained largely unchanged from its Old English roots.

Initially, 'demographic' referred to the statistical study of populations, while 'growing' meant to increase in size. Together, they now describe the expansion of a population group.
