Urban revolution

Urban revolution is when people move from rural (countryside or small towns) areas to cities. Cities get bigger and more people live in them. This happens because living in cities can be more convenient than living in smaller towns. It's usually easier to find jobs, shops, schools and services in cities, so more people want to live there. Urban revolution can lead to more efficient transportation, better communication, and increased economic opportunities.
