He Calculation of population density Is carried out dividing the number of inhabitants of a territory between the extension of this one. The formula is as follows:
Density of population = Number of inhabitants / extent of territory (expressed in km 2 )
The population density Is a figure that establishes a relationship between the territory and the number of people who inhabit it. Data provided by population density are an average, and are usually expressed in inhabitants / square kilometers.
For example, in Spain the population density is 77 inhabitants / km 2 , Which means that in each square kilometer of the Spanish territory there are an average of 77 people.
The density of the population is one of the most important data in demography, which is the science that is in charge of studying the phenomena that affect the populations.
In this sense, population density shows which areas of the territory are most populated and which are the least populated.
For example, population density is highest in Asia, Europe and North America, while in South America, Africa and Australia the population density is lower.
Calculation of population density
The calculation of population density requires knowing two data: the number of inhabitants and the extent of the territory. Various methods are used for counting the population.
Determine the extent of territory
The first data required for the calculation of density is the area of the territory. This is usually expressed in square kilometers.
When the extent of the territory is to be calculated, the limits of the territory must be determined. For this, we must think about what we want the population density figure: for a study at local, state, national level, among others.
According to the object of the study that is wanted to be carried out, the extension of the territory will be delimited.
Determine population
The second data required to calculate density is the population of a country, federal department, city, among others.
One of the main methods is the census, in which a series of officials of a State go house by house, recording the data of the people who live there.
The results of the census are analyzed and published through the institutes in charge of population statistics. It should be noted that the census is the most accurate way to calculate the number of inhabitants.
With some luck, the number of the population will have already been calculated by an organ of the State through the census and the data will be available on the web, in the census books, among others. Otherwise, it will have to be calculated in a personal way.
Another method is sampling, which involves counting individuals within a small area of the territory. This area will be the sample .
This type of technique is used for smaller scientific or social studies, in which researchers do not have the time or the tools to carry out a census.
Once the two data are known, the population is divided between the territory.
