“Demographics is destiny,” is a phrase that is way overused and abused. Demographics isn’t necessarily destiny, but it does play a major role in the rise and fall of civilizations. For example Rome the city at its height of power had over a million residents and controlled 100 million subjects. When Rome fell to the Germanic raiders it had only 50,000 residents left and its control did not extend much outside the city. Demographics is important, which in turn may influence where you choose to invest.
