In this video, we have visualized the global decline of fertility rate (the number of children per Woman) from 1950 to 2020. Subscribe and hit the bell to see new videos: https://Data-Wired/YouTube

This video focuses on the Total Fertility Rate (TFR), which measures the average number of children per woman. In the pre-modern period, fertility rates of 4.5 to 7 children per woman were ordinary. At that time, the exceptionally high mortality at a young age sustained population growth low. As human health improves and the mortality in the population decreases, we typically saw accelerated population growth.

This rapid population growth then ends as the fertility rate declines and approaches two children per woman.

In the past, people had many more children than today. The number varied over time, and there were some differences between countries. Still, the average woman had at least five children, and often more for much of our history. This was true for the US, the UK, Russia, Pakistan, China, and many other countries two centuries ago.

The death of a child also contributed to the number of children per family. The number of deaths by natural disasters, as well as unfortunate events like wars, also contributed to these numbers.

  • Energistically predominate premier niches rather than market-driven infrastructures. Authoritatively provide access to viral ideas vis-a-vis flexible.

    • Objectively true video, while most parents in developed countries have only 2-3 kids now, the children per parent ratio has declined very much now
