Answer:
East Asia, centered on China but extending to Korea and Japan, it contains about one-quarter of the world's population; nearly 1.3 billion in China alone.
India lies at the center of the South Asian concentration with extensions to Pakistan, Bangladesh, and the island of Sri Lanka. This is one of the greatest concentrations of people on Earth with about 1.5 billion people.
Europe, the third-ranking population cluster, also lies in Eurasia but at the opposite end from China. This cluster contains about 700 million people.
Step-by-step explanation:
In Europe, unlike East and South Asia, terrain and environment are not as closely related to population distribution. Another contrast lies in the fact that the majority of the European population live in cities and towns; while the majority of Asians are farmers. Leaving the rural country-side more open and sparsely populated. These contrasts with the East and South Asian clusters reflect the impact of the Industrial Revolution on Europe over the last 200-plus years.
