World Population Will Reach Eight Billion Today, Says UN | India is blooming
Washington/UNI: World population is expected to reach eight billion people on Tuesday and India is expected to overtake China as the world’s most populous country in 2023, according to a report released by the United Nations (UN) citing World Population Prospects 2022 .
The latest UN projections suggest that the world population could reach around 8.5 billion in 2030, 9.7 billion in 2050 and 10.4 billion in 2100.
“This year, World Population Day falls in a pivotal year, as we anticipate the birth of the eight billionth person on Earth.
“This is a time to celebrate our diversity, recognize our common humanity, and marvel at the advances in health that have extended lifespans and dramatically reduced maternal and child mortality rates,” the secretary said. UN General António Guterres.
“At the same time, it’s a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to each other,” he said.
The annual World Population Prospect 2022 report, released on Monday to coincide with World Population Day, also notes that the world’s population is growing at its slowest rate since 1950, after falling to less than 1% in 2020.
While it took 12 years for the world’s population to grow from seven billion to eight billion, it will take around 15 years – until 2037 – for it to reach nine billion, a sign that the overall growth rate of the world’s population slows down.
In 2022, the two most populated regions were both in Asia: East and Southeast Asia with 2.3 billion people and Central and South Asia with 2.1 billion.
China and India, with more than 1.4 billion each, accounted for most of the population of these two regions.
More than half of the projected increase in world population through 2050 will be concentrated in just eight countries: Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania .
Disparate growth rates among the world’s largest countries will rearrange their size rankings.
According to UN estimates, India is expected to overtake China as the world’s most populous country in 2023.
Population growth is due in part to falling levels of mortality, as evidenced by increased levels of life expectancy at birth.
Globally, life expectancy reached 72.8 years in 2019, an increase of nearly nine years since 1990.
Further reductions in mortality are expected to result in a global average longevity of around 77.2 years in 2050.
Countries with the highest fertility levels tend to be those with the lowest per capita income.
Over time, therefore, global population growth has become increasingly concentrated among the world’s poorest countries, most of which are in sub-Saharan Africa.
In these countries, rapid and sustained population growth can thwart the achievement of the Sustainable Development Goals (SDGs), which remain the world’s best path to a happy and healthy future.
Although population growth amplifies the environmental impact of economic development, rising per capita incomes are the main driver of unsustainable production and consumption patterns.
Countries with the highest material resource consumption and greenhouse gas emissions per capita tend to be those with the highest per capita income, not those with rapidly growing populations.
According to the UN, achieving the goals of the Paris Agreement to limit global temperature rise, while achieving the SDGs, depends critically on tackling unsustainable patterns of production and consumption.
