Raise retirement ages!
That’s the simple, clear and unavoidable message that economics
are sending to governments around the world.
Results from the 2020 population censuses in the United States
recently made headlines. But rather than recognizing the social, economic and environmental benefits of slower rates of population growth for the U.S., China and the planet, much of the media stressed the downsides of slower growth and wrote about population collapse
, baby bust
and demographic decline
The demographic impact of the coronavirus one year after being declared a pandemic on 11 March 2020 has been enormous. The picture that emerges is one of significant consequences on the levels and trends of the key components of demographic change: mortality, fertility and migration.
The world is in the midst of the Great Migration Clash, a bitter struggle between those who “want out
” of their countries and those who want others to “keep out
” of their countries. More than a billion
people would like to move permanently to another country and no less than a billion people say fewer or no immigrants
should be allowed to move into their countries.
While the end of life remains the inescapable fate of every man, woman and child, death can be delayed as has been demonstrated
repeatedly throughout human history. Amid the current coronavirus pandemic, a paramount objective is delaying death from Covid-19 for many millions of people across the globe.
It’s an indisputable fact
: the United States leads the world in the number of Covid-19 deaths. As of 15 May, three months after the country’s first confirmed coronavirus death
, the US death toll from the pandemic has reached a remarkable 88,000 deaths
. That rising figure is more than double the number of coronavirus deaths of the next highest country, the United Kingdom at 34,000 deaths
How many COVID-19 deaths will occur before a vaccine becomes available worldwide? As with many seemingly simple questions about an uncertain future, the proper answer to that important query is: “it depends”.
The answer to the critical question of how many immigrants will there be in the future is: far below the number of people wanting to immigrate and far above the number of immigrants wanted. The discrepancy between the two opposing migration “wants” underlies the current divisive migration crisis sweeping the globe.
In addition to its unprecedented rapid rate
of demographic growth during the past 75 years, world population’s distribution across the planet has changed significantly over the past seven decades. The momentous global changes in humanity’s geographic distribution pose serious social, economic, political and environmental challenges and disquieting implications for the future.
What if current fertility rates of countries remain constant for the rest of the 21st century? Under this assumption, the populations of high fertility countries skyrocket while those of most low fertility countries plummet and world population nearly triples in size by the century’s close.
Two, four and eight billion people is the extraordinary doubling and redoubling of the world’s population that occurred in slightly less than a century. World population
, which had grown to 2 billion by 1927, doubled to 4 billion by 1974 and will reach 8 billion by around 2023.
Premarital sex, defined as voluntary sexual intercourse between unmarried persons, is increasing worldwide. While traditional values
, religious instructions
and the laws of some countries
continue to prescribe abstinence until marriage, the rapid societal changes that have occurred across all regions during the past half-century have resulted in the growing prevalence and acceptability of premarital sex.
Most of the world’s women have experienced sexual harassment. Based on available country surveys, it is estimated that no less than 75 percent of the world’s 2.7 billion women
aged 18 years and older, or at least 2 billion women, have been sexually harassed (Figure 1).
Recent elections around the world have clearly shown growing public support
for candidates and political parties advocating the deportation of migrants and stricter restrictions on immigration, including halting it altogether. At the same time, opposition, challenges
and resistance to deportations
and immigration restrictions
have become more widespread, visible and vocal.
Are humanoid robots or androids
a solution to declining and aging populations? Given the prospects of demographic decline and population aging coupled with growing opposition to immigration, countries
are increasingly turning to and investing
in advanced robotics and androids to address shrinking workforces and rising numbers of elderly.
While rapid population growth may be the defining feature of the 20th
century, with world population nearly quadrupling from 1.6 to 6.1 billion, the hallmark of the 21st
century is likely to be population aging.
Global food extremes of chronic undernourishment and obesity have brought about a bipolar world of hundreds of millions of underfed and overfed people. Of the world’s population of 7.5 billion the proportions suffering from chronic undernourishment
and those afflicted by obesity
are similar, approximately 11 percent or together about 1.6 billion people. However, as with most global averages, the levels of both chronic undernourishment and obesity vary enormously among regions and across and within countries.
