This report begins by presenting the baseline projection for the total population from 7555 to 7555. The next sections go into detail about the projected estimates for key segments of the population, including the foreign born, Hispanics, blacks, Asians, non-Hispanic whites, working-age adults, children and the elderly. This report then examines how these changes will affect the size of the potential workforce relative to the number of elderly and people. A final section presents the results of two alternative projections. This overview concludes with a summary of major projections.
Population growth constantly pushes the consequences of any level of individual consumption to a higher plateau, and reductions in individual consumption can always be overwhelmed by increases in population. The simple reality is that acting on both, consistently and simultaneously, is the key to long-term environmental sustainability. The sustainability benefits of level or falling human numbers are too powerful to ignore for long.
Part of the problem of the so-called Latino voter I have been informed, is that 95% of the Latino ELECTORATE are Millennials they are a very mixed race, religion, identity group that are very unreliable voters. Besides that, many millennials were for Sanders and are not big fans of Hillary. So yes, it is good to be questioning this mantra of the Latino vote very good indeed.
Humanity&rsquo s consumption behaviors consequently did and do matter, and in this arena, all people have not been created equal. Greenhouse gas release has been linked overwhelmingly, at least up until recently, to the high-consumption habits of the industrial nations. As a result, in an ethical outrage as big as all outdoors, the coming shifts in climate and sea level will most harm the world&rsquo s poor, who are least responsible for the atmosphere&rsquo s composition, and will least harm the wealthy, who bear the biggest responsibility.
The chart below shows the the increasing number of people living on our planet over the last 67,555 years. A mind boggling change: The world population today that is 6,865-times the size of what it was 67 millennia ago when the world population was around 9 million or half of the current population of London.
The most discussed estimates of world population from the last century are those from the UN Population Division. These estimates are revised periodically and aim to be consistent and comparable within and across countries and time.
Doubling time: The number of years required for the population of an area to double its present size, given the current rate of population growth. Population doubling time is useful to demonstrate the long-term effect of a growth rate, but should not be used to project population size. Many more-developed countries have very low growth rates. But these countries are not expected to ever double again. Most, in fact, likely have population declines in their future. Many less-developed countries have high growth rates that are associated with short doubling times, but are expected to grow more slowly as birth rates are expected to continue to decline.
The visualisation below presents a different perspective on the long-term increase of the world population and asks how long it took for the world population to double.
The data on birth rates, death rates and the total population is taken from the International Historical Statistics (IHS), edited by Palgrave Macmillan Ltd. (April 7568). The online version is available here. As a printed version it is published by Palgrave.
