More than 50% of the world\u2019s population lives within this circle.
\nDo you think it's a coincidence?<\/h2>\n<\/div>\n<\/div>\n

Let's zoom in on the region to analyze the situation.<\/p>\n

\n
\n
\"\"<\/div>\n<\/div>\n<\/figure>\n

India and China together have a combined population of 2.8 billion people, or 35% of the world\u2019s population.
\nBut many other neighboring countries also have massive populations: Indonesia has 274 million, Pakistan 230 million, Japan 126 million, the Philippines 114 million\u2026 And those are just the ones with over 100 million people. All these countries combined account for a little over 50% of the world\u2019s population.<\/p>\n

The Origins of the East and South Asian Population<\/h1>\n

Let's take a closer look at the biggest ones. First, there's India.<\/p>\n

1. India<\/h1>\n

I conducted an in-depth analysis of India, along with Pakistan and Bangladesh, in an article about the Indian subcontinent<\/a>. If you've read the article or thread, or already understand why India has such a large population, skip this section. If not, you might want to check it out now, or simply read this short version:<\/p>\n

  1. The Indo-Australian Plate collides with the Eurasian Plate<\/li>\n<\/ol>\n
    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    2. The collision causes the land to rise.<\/p>\n

    \n
    \"\"<\/div>\n<\/figure>\n

    3. This creates the world's largest mountain range, consisting of the Himalayas, Tibet, the Hindu Kush, the Hengduan Mountains\u2026<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    4. The weight is so great that these mountain ranges are sinking toward the Earth. The surrounding areas sink along with them, becoming flatter and forming valleys.<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    5. Winds carrying a lot of moisture come from the Indian Ocean, hit the Himalayas, rise, the air cools, the moisture condenses, and it rains.<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    This image shows that: India is green on the left, and Tibet is dry on the right.<\/p>\n<\/div>\n<\/div>\n

    6. Some rain falls directly on India\u2014making much of it fertile\u2014and much of the rest falls in the Himalayas and flows downhill. All this water converges in the Ganges Valley, making it very humid and suitable for irrigation.<\/p>\n

    7. The Ganges carries sediment with it, which fertilizes the Ganges and any area it floods.<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>
    Two rivers from the Ganges basin converge. You can see the color of the one on the right, which indicates that it carries a lot of sediment.<\/figcaption><\/figure>\n

    8. Rain, fertilizer, rivers for irrigation, and heat: Perfect conditions for agriculture, which makes India one of the world\u2019s largest food producers. Food = population.<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    Now there\u2019s one more thing: Why does the wind carry so much moisture into India? In this part of the world, that\u2019s not common.<\/p>\n<\/div>\n<\/div>\n

    \n
    \n
    \n

    \"\"<\/div>\n<\/div>\n<\/figure>\n<\/div>\n<\/div>\n<\/div>\n

    \n

    The Horse Latitudes tend to have deserts because the wind blows over the land without any water. Why?<\/p>\n

    Because of the Earth's rotation.<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    The equator is the hottest part of the world because the Sun shines directly on it. This causes water to evaporate and the air to heat up. Hot air is lighter, so it rises; when it reaches the colder air in the upper atmosphere, water condenses and falls as rain. But the air keeps flowing because of the Earth\u2019s rotation! And it descends in the Horse Latitudes, where there is no water. With so much wind blowing downward, other winds have a hard time reaching that area, and there is no rain.<\/p>\n

    So why doesn't it work in India? Because of the monsoon.<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    In the summer, monsoon rains overcome this mass of dry air and bring humid winds to India. How does that happen?<\/p>\n

    Because Eurasia is so big.<\/p>\n

    \n
    \n
    \"\"<\/div>\n<\/div>\n<\/figure>\n

    This part of the world is the only one with a southern ocean and a northern continent. Here's what happens in the summer:<\/p>\n
