Then they analyzed structural dimensions to estimate the household productivity, how quickly monuments were constructed as well as the ancient settlements’ populations and densities. The researchers found that more populous ancient settlements also tended to be the more productive ones. They also found that rate at which this productivity increased was the same as in today’s city environment.
As populations in ancient cities grew, the rate at which they could produce monuments also increased, according to the researchers. They found that the pattern was true of private wealth accumulation. The surface areas of houses tend to become larger as the size of the settlement grew.
