The number of people living per square kilometre can vary greatly depending on the country or region. For example, in densely populated countries like Singapore or Monaco, the population density can be over 10,000 people per square kilometre. In contrast, in sparsely populated countries like Mongolia or Greenland, the population density can be less than 1 person per square kilometre. It is important to note that population density is a measure of the number of people living in a given area and can change over time due to factors such as migration, urbanization, and natural population growth.
