World Population
This PowerPoint is associated with
population statistics of the world and
how population is dispersed throughout
this world.
Current population
• At some point during last year the 7th Billion
person was born on this Earth.
• As of this week the current population of the
World is somewhere in the neighborhood of:
7,211,000,000
http://galen.metapath.org/popclk.html
That means approximately:
• Total births per second: 4.2
• Total deaths per second: 1.8
• Net growth: 2.37 per second
• If we look at a world map… we all have and idea of what it
looks like and we know that the largest continent is Asia
but do you know that he largest countries are Russia
followed by Canada, China and the US in land area.
• But….if we look it a world adjusted population
map, it looks like this:
That means:
• Although Asia has 30% of the world land
area…..on that land is 61% of the worlds
population.
– 17.4 million sq. mi.
– 3.879 billion people
* In other words….. every 6 out of 10 people live in
Asia
Comparison
• In retrospect the US has 3,679,192 sq.
mi……6.5% of the worlds land area
• ….yet with a population of 312,983,800 (the
world 3rd largest country) it only has 22% of
the worlds population.
Population density
• Population density is: population/land area
• The result is the number of people per square
mile.
• Demographics is understanding the
relationships of population between different
areas.
