World to Have 700 Million Fewer People by 2100 Than Estimated: World Population Prospects 2024

The latest report from the United Nations, the World Population Prospects 2024, reveals a significant adjustment in global demographic projections. According to the report, the world is expected to have 700 million fewer people by the end of the century than previously estimated. 

Summarized Insights:

• Global population expected to peak at 10.3 billion by mid-2080s, declining to 10.2 billion by 2100.

• Fertility rates dropping globally, influenced by education and contraceptive access.

• India's population to grow until mid-2060s despite crossing replacement fertility rate.

• Challenges include ageing populations and healthcare demands; opportunities in economic growth.

This revision highlights a critical shift in population dynamics driven by declining fertility rates and changing demographic trends across the globe.

The current global population stands at 8.2 billion and is projected to peak around the mid-2080s at approximately 10.3 billion. 

However, after reaching this peak, the population is expected to gradually decline to 10.2 billion by 2100. 

This decline reflects substantial decreases in fertility rates across many of the world's most populous countries, presenting a pivotal moment for global sustainability and policy adaptation.

One of the primary factors contributing to the earlier-than-anticipated peak in global population is the widespread decline in fertility rates. 

Over the past few decades, fertility rates have dropped significantly, with the global average falling from 3.3 births per woman in 1990 to 2.3 births per woman today. 

More than half of all countries now have fertility rates below the replacement level of 2.1 births per woman. 

This decline is attributed to increased access to education, particularly for women, and improved availability of contraceptives, empowering individuals to make informed choices about family planning.

India, projected to remain the world's most populous country throughout the century, illustrates diverse regional dynamics amidst these global trends. 

Despite crossing the replacement fertility rate, India's population is expected to continue growing until the mid-2060s due to population momentum. 

Experts emphasize that strategic investments in education, healthcare, infrastructure, and job creation are crucial for leveraging India's demographic dividend until the 2050s.

While declining fertility rates pose challenges such as ageing populations and increased healthcare demands, they also present opportunities for economic growth and sustainable development. 

Nations with youthful populations must strategically invest in education, healthcare, and infrastructure to capitalize on demographic dividends effectively. 

Simultaneously, addressing issues like early childbearing and child marriage remains critical for improving women's health, educational outcomes, and workforce participation globally.

Post-COVID-19, global life expectancy has rebounded, reaching 73.3 years in 2024 and projected to rise to 77.4 years by 2054. 

This increase in life expectancy underscores the shift towards an ageing population structure in many parts of the world. 

As populations age, the proportion of elderly individuals grows, posing challenges for healthcare and social protection systems. 

Countries must prepare by investing in healthcare infrastructure and services to meet the needs of an ageing population.

Gender equality plays a crucial role in managing population dynamics. 

Policies promoting women's empowerment, including access to reproductive health services and equitable caregiving responsibilities, are essential for fostering sustainable demographic transitions. 

Addressing issues such as early childbearing and child marriage through educational investments and delaying childbirth can significantly enhance women's health outcomes and societal participation.

In conclusion, the World Population Prospects 2024 report signals a transformative period in global demographics. 

Shifts in fertility rates, healthcare advancements, and socioeconomic factors are reshaping population dynamics worldwide. 

As countries navigate these changes, strategic investments and policies promoting gender equality and reproductive health will play a pivotal role in shaping a sustainable future for generations to come.
