Man-made regulators, such as those attracted by infrastructural development , industrialization, etc., when people settle in a region , are called unnatural regulators of population distribution. The development of industries in the areas rich in mineral resources , agricultural resources , forest resources, etc., created a lot of employment and settlements. If there is an opportunity for better communication in a region, it is easier to maintain communication with different regions, so the population increases there. In areas where there are more opportunities for education , culture , etc. , the population also increases.
