A crowded city is an urban area with a high population density, meaning many people live and work in a small space. This often leads to busy streets, packed public transportation, and a variety of shops and restaurants. Cities like New York and Tokyo are examples where the hustle and bustle create a vibrant atmosphere. In a crowded city, the demand for housing can be high, resulting in tall buildings and apartments. Public services, such as schools and hospitals, may also be stretched due to the large number of residents. Despite the challenges, crowded cities often offer diverse cultures and opportunities.
