The United Nations has predicted that the global population might reach around 8.5 billion in 2030 while the number stands at about 7.7 billion at present.

The UN data published on July 11, World Population Day, said, ‘It took hundreds of thousands of years for the world population to grow to 1 billion but in just another 200 years or so, the global population grew sevenfold.’

According to the global population trend by the UN, in 2011, the global population reached 7 billion mark, and today it stands at about 7.7 billion.

The global population is expected to grow to around 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100, the UN predicts.

This dramatic growth has been driven largely by increasing numbers of people surviving to reproductive age, and has been accompanied by major changes in fertility rates, increasing urbanisation and accelerating migration.

These trends will have far-reaching implications for generations to come. The recent past has seen enormous changes in fertility rates and life expectancy.

According to the Global Population Trend by the UN, in the early 1970s, women had on average 4.5 children each; by 2015, total fertility for the world had fallen to below 2.5 children per woman.

Meanwhile, average global life spans have risen, from 64.6 years in the early 1990s to 72.6 years in 2019. In addition, the world is seeing high levels of urbanisation and accelerating migration.

The year 2007 was the first year in which more people lived in urban areas than in rural areas, and by 2050 about 66 per cent of the world population will be living in cities. They affect economic development, employment, income distribution, poverty and social protections.

They also affect efforts to ensure universal access to health care, education, housing, sanitation, water, food and energy.

To more sustainably address the needs of individuals, policymakers must understand how many people are living on the planet, where they are, how old they are, and how many people will come after them.
