True or False: The growth of global urban populations is driven by the expansion of cities of all sizes.

The statement is true because the growth of global urban populations is indeed driven by the expansion of cities of all sizes. Urbanization occurs as people move from rural areas to urban centers in search of better employment opportunities, education, and living conditions. This trend is not limited to any specific size of city; it encompasses both large megacities and smaller urban areas.

Larger cities often attract a significant proportion of migrants due to their diverse economic opportunities, but smaller cities and towns are also experiencing growth as they develop and offer better services and quality of life. In many developing countries, smaller cities are growing rapidly as people are drawn to them from rural regions, leading to an overall increase in urban population worldwide. This reflects a broader trend of urban expansion that affects cities of various sizes across different regions.

Other options suggest limitations or scenarios that do not accurately reflect the general trend of urbanization, such as focusing only on developed countries or implying that urban growth is restricted to larger cities. These framings overlook the complex dynamics and varied contexts in which urbanization occurs globally.
