According to passage it is irreversible tide one way traffic into the cities, collect a data from researches?

Research studies have shown that urbanization and the movement of people into cities is a global trend that is unlikely to reverse. According to data from the United Nations, more than half of the world's population currently lives in urban areas, and this number is expected to increase to 68% by 2050.

Various factors contribute to this trend, including economic opportunities, access to services and amenities, and social and cultural attractions. As cities continue to grow and develop, they attract more people seeking better job prospects, education, healthcare, and quality of life.

While some efforts have been made to promote decentralization and regional development, the pull of cities remains strong. This one-way traffic into urban areas has significant implications for infrastructure, housing, transportation, and environmental sustainability.

Overall, the data from research studies suggest that urbanization is a long-term and irreversible trend that will continue to shape the future of human settlement patterns.
