Significant factors impacting the data on life expectancy include expectations regarding mankind's ability to reduce the impact of AIDS/HIV and other infectious and non-communicable diseases.Īs a result of the increase in global life expectancy, the majority of the world's countries are undergoing considerable growth in the number of residents over the age of 65. Global life expectancy is projected to continue to increase, reaching 77.2 years by the year 2050. Global life expectancy has also improved in recent years, rising to 72.8 years in 2019-almost 9 years longer than in 1990. Life expectancy and its impact on world population Additionally, multiple nations within Africa are expected to double their populations in the coming decades as fertility rates and birth rates rise thanks in part to advancements in medical care and decreased infant mortality and malnutrition. Particularly of interest is India, which is on track to overtake China's position as the most populous country by the year 2030. More than half of the world's expected population growth between now and 2050 is expected to come from just eight countries: DR Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and Tanzania. The rate of population growth varies greatly from one country or region to another. This decrease continues a trend begun in the 1970s, in which the population growth rate shows a consistent decrease when measured in five-year increments. In 2020, the global population growth rate fell below one percent for the first time since 1950. While the world's total population is expected to continue to rise until roughly 2100, the rate at which the population is rising has been slowly decreasing for decades.

According to the United Nations' 2022 World Population Prospects report, the global population is projected to reach 8.5 billion people by the year 2030, 9.7 billion people by 2050, and 10.4 billion people by 2080, where it will remain until 2100. The world's population continues to increase, with approximately 140 million babies born every year. Rates of population growth around the world The smallest country in the world in terms of both population and total area is Vatican City, where barely 500 people reside. Countries with fewer than 100 million peopleĪs shown in the live-updating population table below, the overwhelming majority of the world's countries have fewer than 100 million people-substantially fewer, in some cases. Additionally, two additional countries, DR Congo and Vietnam, have more than 99 million people and should soon reach the 100 million mark. While Russia and Japan will see their populations decline significantly by 2050, the rest of these nations are expected to continue growing until at least 2050. Countries with more than 100 million peopleĪnother 12 countries each have populations that exceeded 100 million people as of September 2022: Country This contraction, coupled with India's continued growth, is expected to result in India replacing China as the most populous country in the world by the year 2030. While India's population is projected to continue to grow until at least the year 2050, China's population is currently contracting slightly. Only one other country in the world boasts a population of more than 1 billion people: India, whose population is estimated to be 1.41 billion people-and rising. Countries with more than 1 billion peopleĬhina is currently the most populous country in the world, with a population estimated at more than 1.42 billion as of September 2022. After this time, the population growth rate is expected to turn negative, resulting in global population decline. This slowdown is expected to continue until the rate of population growth reaches zero (an equal number of births and deaths) around 2080-2100, at a population of approximately 10.4 billion people. Overall, however, the rate of population growth has been slowing for several decades. The world's population continues to increase by roughly 140 people per minute, with births outweighing deaths in most countries. This total far exceeds the 2015 world population of 7.2 billion. The US Census Bureau's world population clock estimated that the global population as of September 2022 was 7,922,312,800 people and was expected to reach 8 billion by mid-November of 2022.
