There are several synonyms that can be used instead of 'counter-urbanization' depending on the context. Some of these synonyms include 'ruralization', 'deurbanization', 'suburbanization', 'outmigration', 'flight to the countryside', and 'reverse urbanization'. Counter-urbanization typically refers to the movement of people from urban areas to less densely populated areas, so any of these terms can be used to describe this phenomenon. Other related concepts that can be used as synonyms include 'urban sprawl', 'urban decline', 'urban blight', and 'urban decay'. These terms can be used to describe the negative impacts that urbanization can have on certain areas, which may eventually lead to a decrease in urban population.
