World Population Day is observed every year on July 11th. The main purpose of this day is to draw attention towards the issues arising out of increasing population across the globe.
World Population Day is an annual event, observed on July 11th every year, which seeks to raise awareness of global population issues. The event was established by the Governing Council of the United Nations Development Programme in 1989. It was inspired by the public interest in Five Billion Day on July 11th, 1987, the approximate date on which the world's population reached six billion people. World Population Day aims to increase people's awareness on various population issues such as the importance of family planning, gender equality, poverty, maternal health and human rights.
What does this mean for the architecture and engineering sector?
Both the architecture and engineering sectors have to take the ever-growing world population into account in their projects. Houses need to be designed to accommodate more and more people without compromising their quality of life. Cities also need to be designed in such a way that many people can move around as quickly as possible without hindering each other. Efficient means of transport need to be created and existing public transport such as metro, trains and flights need to be adapted to the growing world population.
How much will our population increase in the next 30 years?
Population in the world is currently (2020) growing at a rate of around 1.05% per year (down from 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current average population increase is estimated at 81 million people per year.
Annual growth rate reached its peak in the late 1960s, when it was at around 2%. The rate of increase has nearly halved since then and will continue to decline in the coming years.
The latest world population projections indicate that world population will reach 10 billion people in 2057.
