The Science of Overpopulation

The World's Population Density by Latitude Map Explainer: Key Facts About Ukraine The modern state of Ukraine was formed nearly 30 years ago after the collapse of the Soviet Union in 1991. Since then, the country has often made headlines due to political instability and the looming threat of a Russian invasion. In the map graphic above, we examine Ukraine from a structural point of view. What’s the country’s population composition? What drives the country’s economy? Where Do People Live in Ukraine? With a population of nearly 44 million people, Ukraine is the eighth-most populous country in Europe. As the cartogram below demonstrates, a large portion of the country’s population is located in and around the capital Kyiv, along with the Donetsk region—which is front and center in the current conflict with Russia. Not surprisingly, many of the country’s Russian speaking citizens live on the eastern side of the country, near the Russian border.

Birthrates are declining globally – here's why it matters Birthrates are falling globally. In many countries, COVID-19 has suppressed population growth by causing a decline in births, migration and life expectancy. Even before the pandemic, urbanization was driving population decline. At the end of May, the Chinese Government announced that parents in China would now be permitted to have up to three children. This announcement came only five years after the stunning reversal of the 1980 one-child policy. Something is clearly going on. That something is that China has experienced a fertility collapse. That’s right: 600 and 700 million people, or about half of its total population today. China’s population changes are not unique among the superpowers. You can also add the world’s second-most populous country, India, to the list of low-fertility countries, with a birthrate at replacement rate (2.1). There are still big countries with high birthrates, such as Pakistan (3.4) and Nigeria (5.1). The role of COVID-19 in declining birthrates

Why declining birth rates are good news for life on Earth | Laura Spinney Fertility rates are falling across the globe – even in places, such as sub-Saharan Africa, where they remain high. This is good for women, families, societies and the environment. So why do we keep hearing that the world needs babies, with angst in the media about maternity wards closing in Italy and ghost cities in China? The short-range answer is that, even though this slowdown was predicted as part of the now 250-year-old demographic transition – whose signature is the tumbling of both fertility and mortality rates – occasional happenings, such as the publication of US census data or China’s decision to relax its two-child policy, force it back into our consciousness, arousing fears about family lines rubbed out and diminishing superpowers being uninvited from the top table. The longer range answer is that our notion of a healthy, vibrant society is still rooted in the past. That doesn’t mean we don’t have to adapt to the new reality.

Global population is crashing, soaring and moving 8 Billion and Counting: How Sex, Death, and Migration Shape Our World Jennifer D. Sciubba W. W. Norton & Company (2022) In January 2022, the National Bureau of Statistics of China made a startling announcement: for the fifth year in a row, the country’s birth rate had fallen. As it turns out, many women in China feel that they cannot afford to have more than one child — or any. Almost eight billion people live on Earth; their futures are highly divergent, argues Sciubba, a senior associate at Washington DC think tank the Center for Strategic and International Studies. In Latin America and the Caribbean, eastern and southeast Asia, Europe and North America, Australia and New Zealand, the total fertility rate (TFR), or average number of children a woman is likely to have in her lifetime, was below replacement level (around 2.1 children per woman) in 2020. In some regions, population pressures are exacerbating problems such as poor governance, civil war and environmental devastation.

How Did The World Population Change? | Gapminder In this short video Professor Hans Rosling shows how the size of the world population has changed over time.
