Densely populated cities are cities where a very large number of people live, which leads to a high population density. These cities differ from small and rural settlements in that they are major centers of economy, culture and social life. In such cities there is a developed infrastructure, including a wide network of public transport, many shopping centers, restaurants, cafes and other entertainment venues. In addition, densely populated cities usually have a rich and diverse cultural scene, offering their residents many opportunities for education, entertainment and self-development.
