I think they might want to get away from the rat race and pollution in metropolises. What I mean is that cities are getting more and more polluted than ever before. The streets are crowded and stuck all the time. So if people continue to live in cities, they might suffer from either mental or physical illnesses such as depression, chronic stress and lung cancer. People can enjoy fresh air and immerse themselves into nature when living in the suburbs. Another reason is that people can still earn a huge amount of money when working in remote areas. This is thanks to the Internet development where people can connect and collaborate with each other effortlessly.
