For example the population of Turkey is 79,749,000 people, or as 7.9749 * 10^7 in scientific notation.
The country of Mexico has a population of about 114,975,000 people, or 1.14975 X 10^8. Mexico has approximately 35 million more people than Turkey.
Population density is used to compare how crowded places are around the world. The density of a place might suggest a good place to begin a business, or a good place to advertise a product/service. Others may think that a place with low population density may be a more peaceful place to live with less noise or traffic congestion. How do you feel, would you prefer to live in place with a high or low population density?
Use the websites below to explore places in the part of the world you live, or places that interest you. Here are some questions to include as you explore as you compare world populations.
- How do different cities or countries compare in population ?
- How would the populations be expressed in Scientific Notation?
- How does the population density compare between the cities or countries?

By looking at Density I learned about the ratio of people to land area. It was interesting to me that Turkey had the highest population density of the four countries since Turkey had the second lowest population.
I think that this high density may be caused by it's smaller land area. Another thing I noticed was the lowest population density was from Peru who had just 32 people per square kilometer. The population in Peru is therefore more spread out than the other countries which have a higher density than Turkey.

I like the way bar graphs show population density of different countries. The website at nces.ed.gov/nceskids/createagraph/default.aspx
