The reason for the little growth can be migration.
Migration is the transfer of a population from one geographic area to another in search of better living arrangements, employment opportunities, or social amenities. Factors such as poor air and water quality, a lack of water supply, problems with waste disposal, and high energy use are all made worse by the growing population density and needs of metropolitan areas. Such factors lead to people moving away from their homes.
Effective city planning will be essential for addressing these concerns as well as others as metropolises around the world grow. The wealth gap between urban and rural areas has an impact on migration trends in New Zealand as well. Other benefits of living in an urban area include access to better educational opportunities, water, and the appeal of city lights. Since gaining their independence, migrants have continued to maintain ties to their native villages while residing longer in towns.
