Population Year 2022 - Worldmapper

As I see it, humanity needs to reduce its impact on the Earth urgently and there are three ways to achieve this: we can stop consuming so many resources, we can change our technology and we can reduce the growth of our population. Sir David Attenborough, naturalist and broadcaster

In 2022 world population estimates reached 8 billion; that is 8 thousand million.

Most of the people still live in China, followed by India, the United States of America. Indonesia and Pakistan. The image shown here is expected to change in this century: China is feeling the impact of its one-child-policy and will be soon overtaken by India in total population numbers, Nigeria will take over the USA to become the third-most populated country. Global population growth has started shifting away from Asia towards the African continent, with Nigeria's ongoing growth being a main symbol for the continent's future young generations, while many other regions of the world started seeing stagnating or even declining population numbers, along with new demographic challenges such as a declining workforce and ageing societies.

Gesellschaft - Weshalb wir den Begriff «Familie» überdenken müssen

# data[].attributes.attachment_link.description
Seit Jahrzehnten ist die Kleinfamilie die Norm. Doch nun gerät sie unter Druck – von immer mehr alternativen Familienmodellen. Die Gesellschaft verliert einen gemeinsamen Wert. Schlimm ist das nicht.

# data[].attributes.attachment_link.description
Im Lauf der Jahrhunderte hat sich das Familienbild immer wieder verändert. Dabei konnte und kann Familie viel mehr sein als Vater, Mutter, Kind: zum Beispiel Sippe, Stamm, Dynastie, Hausgemeinschaft oder Patchwork.
