Global population is projected to reach 10 billion by 2050, more than double the estimated 7.7 billion today. this significant population growth is expected to occur primarily in africa and asia, and is attributed to a decrease in the global fertility rate from 4.7 children per woman in 1960 to 2.5 in 2017. additionally, the population of the world’s least developed countries is projected to double by 2050, while the population of the world’s most developed countries is expected to remain relatively stable.
Population growth has been occurring since 1960, when the world’s population was less than half of what it is today. this growth is expected to continue in the coming decades, with the global population reaching its peak in the late 21st century. additionally, the global population growth rate has been declining since the 1960s, and the population is becoming increasingly urbanized, diverse, connected, and educated.
Global population growth is happening due to a decrease in the global fertility rate, which has resulted in fewer children being born. this has resulted in an aging population, with the number of people aged 65 and over expected to triple by 2050. additionally, the population is becoming increasingly diverse, with over half of the world’s population living in countries with more than one ethnic group, and increasingly connected, with over half of the world’s population having access to the internet. the population is also becoming increasingly educated, with the number of people with a college degree expected to double by 2030.
