CITY DENSIFICATION - People are increasingly moving from rural to urban areas. There are numerous reasons for this. For example, many young people move to major cities to study or work. However, the middle-aged and seniors also prefer to stay in cities or move to them due to the entertainment and recreational possibilities they offer. Furthermore, the social trend towards living single leads to more people looking for connection in the anonymous and diverse environment of a big city. Accommodating the large number of new residents requires a lot of living space. This means denser housing development, i.e. more buildings that are bigger and taller.
