World Travel City Photography

The first true towns are sometimes considered to be large settlements where the inhabitants were no longer simply farmers of the surrounding area, but began to take on specialized occupations, and where trade, food storage and power was centralized. In 1950 Gordon Childe attempted to define a historic city with 10 general metrics. These are:
1. Size and density of the population should be above normal.
2. Differentiation of the population. Not all residents grow their own food, leading to specialists.
