China's population exceeded 100 million due to which factor?

• A. Industrial Growth
• B. Population Growth
• C. Urbanization
• D. Migration

Answer: (B)

The main idea here is natural population growth—the idea that a population increases when births outnumber deaths over a long period. When a society sustains birth rates higher than death rates, the total number of people climbs, eventually passing milestones like 100 million. In historical contexts, improvements in agriculture and living conditions boosted food supply and reduced mortality, while families often remained large, driving a steady natural increase. Industrial growth is about economic development and doesn’t by itself raise the total number of people. Urbanization describes more people moving to cities, which changes where people live but not the overall count. Migration shifts populations between places and regions, again redistributing people rather than creating them. So the factor that explains surpassing 100 million is natural population growth driven by births exceeding deaths.
