                                                                                                             they are located near water

                                                           Another global trend is that the populations are distributed in clusters rather
                                                          than spread evenly around each country. This also may be because it is easier
                                                             for people to be near each other as they can buy food and other utensils
                                                               without having to cross the planet (Most people are also very social
                                                          creatures). There are many exceptions dotted all over each country except for
                                                            Australia which is largely inhospitable at its epicenter. These exceptions are
                                                               mainly due to faster transportation. Smaller communities dispersed
