World Population Day is observed every year on 11th July to raise awareness about the growing population and the challenges that come with it. This day aims to highlight population-related issues such as family planning, gender equality, maternal health, and human rights. Each year, a specific theme is chosen to bring focus to a key concern. Here’s why this day is important:

• Reminds us about the impact of overpopulation on resources and the environment.
• Encourages discussions on reproductive health and rights.
• Highlights the need for youth education and empowerment.
• Supports efforts to achieve sustainable development goals (SDGs).

World Population Day was created to bring global attention to the challenges and opportunities presented by population growth. The idea was born out of growing global concerns about how population trends affect health, development, and the environment.

• The concept was suggested by Dr. K.C. Zachariah, a senior demographer at the World Bank, who played a key role in proposing that this day be commemorated.
• It was inspired by the “Day of Five Billion” on 11 July 1987, when the world’s population reached 5 billion.
• In 1989, the United Nations Development Programme (UNDP) proposed the observance of World Population Day.
• The UN General Assembly, in December 1990, officially decided to continue celebrating World Population Day every year to raise awareness of population issues and their link to the environment and development.
• The first World Population Day was observed on 11 July 1990, in over 90 countries around the world.

Since then, the day is marked globally through campaigns, awareness drives, educational events, and media outreach to promote informed decision-making on population-related issues.

"The power of population is indefinitely greater than the power in the earth to produce subsistence for man." — Thomas Robert Malthus, (English economist and demographer)

The global population has been growing at an unprecedented pace, raising important concerns about sustainability, resource use, and quality of life. As we observe UN World Population Day 2025, it’s essential to understand the current population trends and their implications for the future.

• The world’s population has tripled since the mid-20th century, reflecting rapid growth over just a few decades.
• As of July 2025, the global population stands at 8.2 billion, according to the United Nations.
• The population is projected to reach 9.7 billion by 2050, and peak at 10.4 billion in the 2080s.

Here are the top 5 most populous countries in 2025:

Together, these five countries account for nearly 46% of the global population (~8.2 billion in 2025).

India’s Population Status

• India is now the most populous country, with 1.46 billion people, overtaking China, which has 1.41 billion.
• According to the UNFPA’s 2025 State of World Population Report, India’s Total Fertility Rate (TFR) has dropped below the replacement level (2.1), indicating a slowing growth trend.
• Despite this, India’s population is expected to grow to 1.7 billion before it starts declining around 2065.
• As of 2025, the five most populous states in India are Uttar Pradesh, followed by Bihar, Maharashtra, West Bengal, and Madhya Pradesh. 

Population growth can bring several serious challenges, especially when not managed with proper planning and policies. As the world population crosses 8.2 billion in 2025, the strain on global systems is becoming increasingly evident. Major challenges include

1. Pressure on Natural Resources: Increased demand for water, food, land, and energy leads to overexploitation of natural resources, contributing to climate change, deforestation, and biodiversity loss.

2. Unemployment and Underemployment: Rapid population growth outpaces job creation, resulting in rising unemployment, especially in developing countries.

3. Urban Overcrowding: Cities face housing shortages, inadequate public transport, and poor sanitation due to population concentration in urban areas.

4. Healthcare and Education Gaps: High population densities can strain healthcare systems and limit access to quality education, especially in low-income regions.

5. Poverty and Inequality: Population growth intensifies economic inequality, with limited access to resources and opportunities for the poor.

6. Environmental Degradation: More people means more waste production, more emissions, and greater pressure on ecosystems, pushing us beyond planetary boundaries.

Tackling these challenges requires strong political will, long-term planning, and the empowerment of communities.

The theme of World Population Day 2025—"Empowering young people to create the families they want in a fair and hopeful world"—calls for focused efforts on awareness, healthcare access, and informed decision-making.

Key Steps Ahead:

• Strengthen Policies: Ensure effective implementation of schemes like National Population Policy (2000), Mission Parivar Vikas, and the Population Stabilization Fund.
• Grassroots Action: Facilitating ASHA workers, surveys, and reproductive health campaigns to reach rural communities.
• Youth Empowerment: Promote education and awareness to help youth make informed family planning choices.
• Community Participation: Support activities by NGOs and health institutions. Rallies, street plays, poster contests, and radio shows can work to spread awareness.
• Collaborative Approach: Encourage coordination between government, civil society, and healthcare providers for long-term population stability.

By investing in awareness and access, especially for the youth, we move closer to a balanced and sustainable future.
