World Population from 1994 to 2014

By: Cameron Karaba

Question

What is the percent of change for world population from 1994 to 2014?

Information

1994 = 5,661,086,346 billion people

2014 = 7,243,784,121 billion people

Equation

Difference / Original = Percent of Change

World Population Percent of Change = 27.96% increase

How I Solved the Problem

7,243,784,121 - 5,661,086,346 = 1,582,697,775

1,582,697,775 / 5,661,086,346 = 0.279574922244085

Then you would round it to = 27.96%

Reaction to the Percent of Change

If population were to stay the same it would mean that for every 1 person that died 1 person would be born.  However the percent of change that I found would mean for every 1 person that died 30% more people are born.  Yes, I am surprised at the birth rate. I thought it was only going to be a 4 to 1 ratio.

Four Component

Future Percent of Change Information

2014 = 7,243,784,121 billion people

2034 = 8,681,569,042 billion people

Percent of Change = 19.85% increase

How I solved the future Percent of Change

8,681,569,042 - 7,243,784,121 =1,437,784,921

1,437,784,921 / 7,243,784,121 = 0.198485335424589

then you would round it to = 19.85%
