Global Population Likely to Reach 8.5 Billion in 2030: UN

The United Nations on World Population Day on Saturday revealed in its world population trend that the number of global population stands at about 7.7 billion.

“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,” the UN data shows.

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

The global population is expected to grow to about 8.5 billion by 2030, 9.7 billion by 2050, and 10.9 billion by 2100, as per the UN prediction.

This rapid rise has been propelled primarily by a growing amount of people who enter the reproductive period and has been followed by significant shifts in birth levels, rising urbanization and accelerating migration.

Such trends will have far-reaching consequences for future generations. In the recent past, there have been huge changes in fertility and life expectancy.

According to the UN Global Population Trend, women had an average of 4.5 children each in the early 1970s; by 2015, peak fertility worldwide had declined to less than 2.5 children per woman.

While global average life expectancy has 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.

The year 2007 was the first year in which more people lived in urban areas than in rural areas, and by 2050 about 66 percent of the world population will be living in cities.

Megatrends & far-reaching implications

They affect economic growth, employment, income distribution, deprivation and social security.

It also impacts attempts to maintain equal access to health services, healthcare, accommodation, sanitation, water, food and energy.

To order to adapt more sustainably to the needs of individuals, policymakers need to consider how many people exist in the world, where they are, how old they are, and how many others may come after them.
