In this article, we list and discuss the 20 Most Populated Countries in Asia. If you would like to skip our detailed discussion of the topic, you can go directly to the 5 Most Populated Countries in Asia.
A century ago, the world population stood at only 1.8 billion people. However, as the years have passed, we have seen a rise in the global population count. At first, this was a slow increase. Eventually, however, the world’s population started snowballing — especially in recent years. As of 2024, according to the United Nations, the global population has crossed the 8 billion mark.
Even though the population has risen worldwide, there are some countries and regions that carry the burden of a rapidly rising population the most. That’s because population distribution is heavily dependent on land area. Note that the keyword here is heavily, not completely (we’ll expand on this in a bit). For example, with 48 countries and three territories, Asia is the largest continent by land as well as population — hosting 59.76% of the global population.
Population Distribution in Asia
Just like with the rest of the world, the population is unevenly distributed within Asia as well. For example, South Asia is the most populated part of Asia with over 2 billion people, while Central Asia is the least populated part, with a population of only over 78 million people.
Above, we’ve stated that population distribution depends heavily but not completely on land area. That’s because, if it did completely, the smallest country in Asia by land area, Macau, would also be the least populated country in Asia. However, that is not the case — Maldives, with a population of 521,021, beats Macau to it.
Despite being the least populated country in Asia, the economy of Maldives has maintained its robust growth performance in 2023 and is expected to grow at an average growth of 5.4% from 2024 to 2025, according to the World Bank. Tourism is the major sector of the country, accounting for almost one-third of the economy.
The Link Between Population Growth & Economy
The richest country in Asia is Singapore in terms of GDP per capita (See: 23 Richest Countries in Asia by GDP Per Capita in 2023). Although the country has a population of only 5,637,022 people, Singapore has a GDP per capita of $133,110 as per 2023 data. At the same time, it’s important to note that Singapore is not the most populated country in Asia, nor the largest or the smallest. Does this mean there is no line between population growth and the economy? No, because people make the economy. Therefore, population growth does affect a land’s economy, both, positively and negatively.
For instance, if there’s a shortage of workers as well as adequate resources, a rise in demand will result in an increased supply of goods and services, which will result in economic growth. On the other hand, if there is a surplus of workers and inadequate resources in an economy, there simply won’t be enough jobs, resources, or goods available for the people. So, the direction in which population impacts the economy depends on the availability of the land’s resources.
It is also important to note that, with increased economic activity, highly populated regions are also subject to high levels of pollution. As the demand for more industrial work rises and the stress on limited resources (like land, housing, educational institutions, healthcare, and non-renewable energy like electricity and fossil fuels) increases, pollution becomes inevitable.
For instance, India, the most populated country in the world, also ranks as one of the top five most polluted countries (See: 30 Most Polluted Countries in the World Heading into 2024). Concurrently, India is also one of the fastest-growing economies in the world. It hosts some of the leading global companies, such as Sony Group Corp (NYSE:SONY), and Tata Motors Ltd (NYSE:TTM).
Both of these are among the most prominent companies in Asia, alongside other names like Alibaba Group Holding Limited (NYSE:BABA) and the Taiwan Semiconductor Manufacturing Company (TSMC). Alibaba Group Holding Limited (NYSE:BABA) — a Chinese multinational technology company — has recently exited the Indian market as it sold its remaining stake in Paytm. As for the rest of Asia, the company continues to expand. In March 2024, Alibaba Group Holding Limited (NYSE:BABA)’s media and entertainment arm pledged $640 million over five years to promote Hong Kong’s creative industries globally.
On the contrary, Sony Group Corp (NYSE:SONY) and Tata Motors Ltd (NYSE:TTM) have a huge market within India, the rest of Asia, and worldwide too. Recently, Sony Group Corp (NYSE:SONY) has joined a venture with Honda and announced its new electric car prototype, Afeela. The two companies aim to sell EVs in the North American market by 2026. Tata Motors Ltd (NYSE:TTM) is set to invest around $2 billion in EV battery models by 2027, aiming for EV-only dealerships across India and possibly in overseas markets.
