New Brunswick at the Dawn of a New Century
IV. WHERE ARE WE GOING?
A. Global Trends
Over the past three decades, many parts of the world have undergone remarkable
demographic, social, economic and political change. Many countries have
made substantial progress in expanding access to reproductive health care
and in lowering death rates. In addition, in many nations, levels of education
and income levels have improved, particularly for women.
As the 20th century draws to a close, three demographic trends loom especially
large on the horizon: the aging of the world's population, the growth of
cities, and the urgent need to bring population growth and growing needs
more into balance with available resources, while limiting the pace of environmental
destruction.
We are burdensome to the world, the resources are scarcely adequate
to us, and our needs strain us and complaints are everywhere while already
nature does not sustain us.

Population Dynamics
The rate of global population growth increased from approximately 2 per
cent over a thousand year period to 2 per cent per year during the 1950's.
Despite the fact that fertility rates are beginning to drop, the world's
population is growing on average by 1.8 per cent a year. Global population
grows by 240,000 every day, and by over 95 million every year; the equivalent
of three Canada's or another Mexico.
The world's population now stands at 5.4 billion, and there will be approximately
6.25 billion people living on the planet by the turn of the century. With
the momentum of population growth, it is conceivable that another 3 billion
people will be added to the planet between 1985 and 2025.
The triad of excessive population growth, environmental degradation
and poverty threaten us and our planet as never before.

Century, Amsterdam, 1989 |
Population Aging
The change brought about by demographic transition affects not only the
rate of population growth but transforms the population age structure.
The demographic transition to an older population structure is proceeding
very quickly in many countries. By 2025, more than 12 per cent of the population
of less developed regions will be over 60 years of age. In more developed
regions the proportion of elderly people will exceed 25 per cent.
In an extensive United Nations study conducted in 1988, it was observed
that despite their current youthful populations, developing countries will
experience the most rapid aging during the next several decades, and after
the turn of the century they will contain the vast majority of the world's
older persons. By the year 2025, more than 70 per cent of the world's elderly
population will reside in developing regions.
If we do not get population growth under control, habitat on Earth will
be destroyed by ecological disaster and/or violent migration processes.

Urbanization
According to the United Nations, another very significant demographic
development of the twentieth century has been the increase in the number
and proportion of persons living in urban areas. The world's urban population
has grown fivefold, a rate of growth that outstrips the world's ability
to provide adequate housing, services, education and jobs. In 1900, about
14 per cent of the world's population lived in cities. By 1980, that figure
had exceeded 40 per cent.
B.A North American Perspective
Canada is expected to experience even greater relative demographic aging
than the United States, Europe, and many other parts of the world. In 1989,
only 10 percent of Canada's population was 65 years or older. By 2020 however,
19 percent of Canada's population will be 65 and over, compared to, for
instance, 16 percent for both the United Kingdom and the United States.
Canada and the United States are expected to have a major slowdown in
the growth of their workforce. Given slower labor force growth and the rapid
pace of technological change, governments, corporations and unions in Canada
and the United States will have to place more emphasis on continuing education,
training and retraining of workers to meet the actual skill levels required
by employers and society -- a task that is already underway in New Brunswick.
The Census Bureau projects that there will be more than 35 million Americans
over 65 by the turn of the century, accounting for nearly one-seventh of
the population. By 2040, the National Institute on Aging projects that 87
million Americans will be over 65. By 2080, there are expected to be 5 million
centenarians.
