By the year 2025, how many people is China expecting to reside in entirely new cities?

China is projected to experience significant urbanization, with expectations for a vast number of people relocating to entirely new cities by 2025. The figure of 350 million is based on various reports and forecasts regarding China's continuing migration patterns and urban development strategies. This expectation reflects China's aggressive urbanization policies, which include the development of new urban areas to accommodate its growing population and to stimulate economic growth.

The rapid growth of urban areas is a component of China's broader efforts to enhance infrastructure, improve living conditions, and optimize resource distribution. This massive movement of people indicates a trend towards creating modern urban environments that can support a higher quality of life and more efficient services.

Considering the alternatives, the figures provided (150 million, 250 million, and 450 million) do not align with the current urbanization trends and government projections for 2025. The chosen number, 350 million, accurately mirrors the anticipated scale of urban migration in China, hence reflecting a deeper understanding of the country's urbanization trajectory.
