Which development gave birth to modern societies, where a person’s identity is based on overlapping group affiliations rather than the concentric ones of premodern societies?

The growth of urban population centers.

Explanation:

The increase of the urban population centers helped a man to find his status. The industrialization was the reason for the growth in urban centers. Industries led to the rise in the population in the urban area because it brought opportunities for the people to earn money. The modern society broke the old tradition of the landlord in the rural areas which led to the shift of the population.
