today in class we worked on comparing different statistics for the different countries in the world. we compared the united States , china, France, Mexico and Canada. we compared them in many different categories. we also talked about the amount of kids born versus the amount of woman. to have the population stay constant the number has to 2.5. if the number is lower than that it probably means that the population is decreasing. if the number is higher than that it means that the population is going up.
