It Took Hundreds of Thousands of Years for World Population to Grow to 1 Billion – Then in Just Another 200 Years or So, It Grew Sevenfold… Today, It Stands at About 7.7 Billion

11 July 2021 (United Nations)* — In this second year of COVID-19, we are suspended in an in-between state, where parts of the world are emerging from the deep recesses of the pandemic while others are locked in battle with the coronavirus as access to vaccines remains a distant, deadly reality.

The pandemic has compromised health care systems particularly in the area of sexual and reproductive health. It also exposed and exacerbated gender-based inequities: gender-based violence increased under lockdown, as did the risk of child marriage and female genital mutilation as programmes to abolish the harmful practices were disrupted.

Significant numbers of women left the labour force – their often low-paying jobs were eliminated or caregiving responsibilities for children learning remotely or for homebound older people increased – destabilizing their finances, not just for now but in the long run.

Against this backdrop, many countries are expressing growing concern over changing fertility rates. Historically, alarmism over fertility rates has led to abrogations of human rights.

UNFPA advises against reactionary policy responses, which can be extremely harmful if they violate rights, health and choices. The agency emphasizes that women must be empowered educationally, economically and politically to exercise choice over their bodies and fertility.

World Population Dashboard

The World Population Dashboard showcases global population data, including fertility rate, gender parity in school enrolment, information on sexual and reproductive health, and much more. Together, these data shine a light on the health and rights of people around the world, especially women and young people.

World Population Trends

It took hundreds of thousands of years for the world population to grow to 1 billion – then in just another 200 years or so, it grew sevenfold. In 2011, the global population reached the 7 billion mark, and today, it stands at about 7.7 billion, and it’s expected to grow to around 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100.

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 urbanization 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. 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 lifespans 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 urbanization and accelerating migration. 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.

These megatrends have far-reaching implications. 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.

Never before had population grown so rapidly – in 1950, five years after the founding of the United Nations, world population was estimated at around 2.6 billion people. It reached 5 billion in 1987 and 6 billion in 1999. In October 2011, the global population was estimated to be 7 billion. A global movement “7 Billion Actions” was launched to mark this milestone.

The world’s population is expected to increase by 2 billion persons in the next 30 years, from 7.7 billion currently to 9.7 billion in 2050 and could peak at nearly 11 billion around 2100.

We have the inherent right to choose what we do with our body, to ensure its protection and care, to pursue its expression. The quality of our lives depends on it. In fact, our lives themselves depend on it…
