Another thread about world's population reaching 7 billion got me thinking

about how fast it has increased in just the last 50 years...

I have an old Rand McNally World Atlas from 1965 listing population by nation, I also have a 2011 World Almanac listing projected population for year 2050, current population figures are from wiki....

Here's a list of top 50 most populous countries...

Some are "loosing" population:Germany and Japan

Some are increasing population rapidly:Ethiopia

Ironically poorer nation's population are increasing

and some of the richer nations are almost stagnant

What I find interesting is countries like Saudi Arabia having only

7 million in 1965, similar to Switerland, now above 25 million

Also democratic Congo with only 16 million in 1965, now over 70 million

*= Pakistan 1965 population includes East Pakistan (now Bangladesh)

**= Germany 1965 population is "combined" East & West Germany
