Does a Doubling of Population Necessitate a Doubling of Government Spending?

Overcoming Bias:
Doubling the population of any city requires only about an 85% increase in infrastructure, whether that be total road surface, length of electrical cables, water pipes or number of petrol stations. This systematic 15% savings happens because, in general, creating and operating the same infrastructure at higher densities is more efficient, more economically viable, and often leads to higher-quality services and solutions that are impossible in smaller places. Interestingly, there are similar savings in carbon footprints — most large, developed cities are ‘greener’ than their national average in terms of per capita carbon emissions.
