Yes, that is billion with a “B”. For you mathematicians that is: 7,100,000,000 If you want to get a real-time feel for how fast the world population is growing (along with a bunch of other interesting statistics) go to: World Meters ( ) . Remember, most of these counters and statistics are estimates, so they might differ by a few million with others you may find on the web. You now also know that world population is heading for just over 9 billion by 2050 (~9.3 billion) and some estimates put the world population at over 10 billion by 2100. Putting it another way, the world population will increase by about 30% in your lifetime. I hope you and I both are still around in 2050. And, yes, everyone will need to eat! Now, what are the three largest population countries? Well, if you guessed China, India and the US (followed by Indonesia and Brazil) you were right on. China and India are converging at about 1.3 billion each. I say converging, because their population growth curves are actually starting to move in opposite directions ( See Figure 1 below ).

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
