A Metropolitan Municipality is a large urban area that encompasses a city and its surrounding suburbs and towns. It is governed by a single municipal authority, which manages various services such as transportation, waste management, and public safety. This structure allows for more efficient administration and resource allocation across the entire region. These municipalities often have a diverse population and play a crucial role in regional economic development. They typically provide essential services like education, healthcare, and infrastructure, ensuring that residents have access to necessary amenities. Examples of such municipalities include Los Angeles County and Toronto.
