Meaning of Population Density
What is Population Density:
Population density refers to the average number of inhabitants per square kilometer in an area or area.
In this sense, population density provides a general knowledge of the conditions of the inhabitants of a country, state or territory, since, the more densely populated a place is, the quality of life is usually lower if there is no urban planning and adequate social.
Population density is also referred to as relative population and differs from absolute population by the latter representing the total number of inhabitants in a place.
Population density is important because it more accurately defines living conditions in certain cities.
See also Density.
For example, according to the National Institute of Statistics and Geography (INEGI), in 2017 Mexico had an absolute population of 123.5 million inhabitants, being the second most populated in Latin America and the eleventh worldwide.
Even so, the population density of Mexico with 62 inhabitants / km2 is far from the first place held by Macao with 21,346 inhabitants / km2. On the other hand, if we compare the population density of Mexico City, which has a population of 8,811,266 in 1,485 km2, resulting in 5,934 inhabitants / km2, we obtain a number that gives us a more accurate image of this great city.
In geography, population density is an essential variable for human geography that studies the relationship between society and its physical space.
