A. What does population density mean?

Population density of a place (country, state, city, county,  providence) or area is the equivalent of how many people there are  per square mile of the place. It is computed by dividing the totalpopulation of the place by the area of the place - usually in  square miles in the US. In most of the world, the area would be  measured in square kilometres.

- For example, the United States has a population density of  83.022 people per square mile.

I hope this helped! :)

i believe that if you say you can, you cant and if you say you can't your right. i believe i can do anything i set my mind to. i've applied this with my everyday life. it me get motivated to do stuff.for example, i apply this to do school. if i believe i can finish a whole class in a couple of week's i will be motivated to do the class until i finish it, and if i believe i can't, i will get distracted and do other stuff besides doing my work. it changed me by believing i can accomplish anything i set my mind to.
