Countries with the largest population 2024

In 2022, India overtook China as the country with the largest population in the world, and now has more than 1.44 billion people. China now has the second-largest population in the world, still with just over 1.4 billion inhabitants, however its population went into decline in 2023.Global populationAs of 2024, the world's population amounts to more than eight billion people, and is expected to reach around 10.4 billion people by the end of the century. Due to improved healthcare, sanitation, and general living conditions, the global population continues to increase; mortality rates (particularly among infants and children) are decreasing and the median age of the world population has steadily increased for decades. As for the average life expectancy in industrial and developing countries, the gap has narrowed significantly since the mid-20th century. Asia is the most populous continent on Earth; 11 of the 20 largest countries are located there. It leads the ranking of the global population by continent by far, reporting four times as many inhabitants as Africa. The Demographic TransitionThe population explosion over the past two centuries is part of a phenomenon known as the demographic transition. Simply put, this transition results from a drastic reduction in mortality, which then leads to a reduction in fertility, and increase in life expectancy; this interim period where death rates are low and birth rates are high is where this population explosion occurs, and population growth can remain high as the population ages. In today's most-developed countries, the transition generally began with industrialization in the 1800s, and growth has now stabilized as birth and mortality rates have re-balanced. Across less-developed countries, the stage of this transition varies; for example, China is at a later stage than India, which accounts for the change in which country is more populous - understanding the demographic transition can help understand the reason why China's population is now going into decline. The least-developed region is Sub-Saharan Africa, where fertility rates remain close to pre-industrial levels in some countries. As these countries transition, they will undergo significant rates of population growth

于2022年，印度超越了我国，成为世界上人口最多的国家，目前人口已超过14.4亿。我国目前位居世界第二人口大国，尽管人口略超14亿，但自2023年起，我国人口开始出现下降趋势。截至2024年，全球人口已超过80亿，预计到本世纪末将达到约104亿。得益于医疗保健、卫生状况以及总体生活条件的改善，全球人口持续增长；死亡率（尤其是婴幼儿死亡率）持续下降，而全球人口的平均年龄已稳步上升数十年。至于工业化和发展中国家的平均预期寿命，自20世纪中叶以来，两者之间的差距已显著缩小。亚洲是地球上人口最多的洲际；其中20个最大国家中的11个位于该洲。亚洲在按洲际划分的全球人口排名中遥遥领先，其人口是非洲的四倍。人口转变在过去两个世纪中的人口激增是人口转变现象的一部分。简言之，这一转变源于死亡率的急剧下降，进而导致生育率的降低和预期寿命的增加；在这一低死亡率和高生育率的过渡期，人口激增现象发生，随着人口老龄化，人口增长可以保持较高水平。在当今最发达的国家，这一转变通常始于19世纪的工业化，而现在随着出生率和死亡率的平衡，增长已趋于稳定。在欠发达国家，这一转变的阶段各不相同；例如，我国在转变阶段上晚于印度，这解释了为何我国人口现在开始出现下降。最不发达地区是撒哈拉以南非洲，一些国家的生育率仍接近工业化前的水平。随着这些国家进入转变期，它们将经历显著的人口增长率。
