These days many people are migrating to cities. I think it is a positive development because it causes increasing rate of manufacturing and workforce in the town.
One of the crucial positives of living in large city is that abundance of employment opportunities. Big cities are often economic centres and offering a wide range of job opportunities in various industries. This can be especially appealing to young professionals who are planning to begin their careers. In addition, enormous towns have some chances for residents to start their business career.
On the other hand, a primary negative side of rising number of people moving to major cities in recent times is that higher cost of living in big towns often incorporate increased expenses for housing, utilities and transportation.

A further negative, which is increased pollution and traffic congestion are common issues in large cities due to the high population density and the heavy use of vehicles.
