Global Demographic Trends

The Demographic Trends that Will Shape the World -- Joseph Chamie, Real Clear World

While governments and institutions try to grapple with economic uncertainty and volatility an important factor of relative certainty is often overlooked: demography. One may not know how the markets will behave, but demographic trends can provide instructive and relative certainty for the near term to deal with debt, taxes, unemployment and entitlements, to name a few. Dismissal of major demographic trends, seven of which described below, will in all likelihood result in ill-conceived policies, unsustainable programs and squandered resources. First, at an estimated 7 billion, the world's population is growing at 1.1 percent annually, or 78 million people, half the peak level of 2.1 percent in the late 1960s. Although the world's demographic growth rate is continuing to slow due to declining birthrates, the 8 billion world population mark will likely be reached by 2025. This growth will increase the world's working age population, 15 to 64 years, by 610 million and those aged 65 years and older by 290 million, increases of 13 and 52 percent, respectively.

My Comment: There are a lot of stats in this report .... bottom line .... the world in 2050 will not look like the world today.

Welsh And Cornish Are The 'Purest Britons'

Welsh And Cornish Are The 'Purest Britons', Scientists Claim -- The Telegraph

Natives from Wales and Cornwall could hold the title for the "purest" Britons, a scientific study suggests.

Scientists drew up a map of the British Isles revealing the genetic ancestry of people from different rural areas across the UK.

After extensive DNA surveying, they found that Welsh and Cornish people were among the most genetically distinct groups in the country.

One theory for the difference in their DNA is that they are a "relic" population, tracing their ancestry back to the tribes that colonised Britain after the last Ice Age 10,000 years ago.

A Doomsday Scenario For The Japanese?

Lack Of Babies Could Mean The Extinction Of The Japanese People -- FOX News

Japan has a problem, a lack of children, and it seems likely there will be even fewer in the future.

Japanese researchers have now warned of a doomsday scenario if it carries on this way with the last child to be born there in 3011 and the Japanese people potentially disappearing a few generations later.

Academics from the city of Sendai, which was hit hard by last year's tsunami, calculate there are now 16.6 million children under the age of 14 now in Japan.

My Comment: The population is going to decline .... that is the world trend .... but I doubt that it will go to zero.

The Changing Face Of America: Time-Lapse Map Reveals How Non-Whites Will Become The Majority In U.S. Within 30 Years -- the Daily Mail

By the year 2040, the majority of Americans will be people of colour - the minorities will have become the majority.

A fascinating new time-lapse map shows the increase in the non-white population across the decades.

It starts with 1990 and then predicts up to 2020, 2030 and 2040.

From Science Daily:

In a study published in the September 24th issue of Nature, an international team describes how they harnessed modern genomic technology to explore the ancient history of India, the world's second most populous nation.

The new research reveals that nearly all Indians carry genomic contributions from two distinct ancestral populations. Following this ancient mixture, many groups experienced periods of genetic isolation from each other for thousands of years. The study, which has medical implications for people of Indian descent, was led by scientists at the Centre for Cellular and Molecular Biology (CCMB) in Hyderabad, India together with US researchers at Harvard Medical School, the Harvard School of Public Health and the Broad Institute of Harvard and MIT.
