population density expressed in the number of resident population per square kilometer is called population density.There are various indicators of density: the density of the township, city, region, country.
Why keep records of this density?The reasons are many.The main among them - the forecast of labor resources of the region in particular the present and future time, with the aim of building (or closure) of social institutions (gardens, schools, institutions, and so forth.), Residential buildings, factories and mills opening, etc.Desert area and large water space when calculating density generally omitted.For the population of the rural and urban population figures are used separately.
population density by continents, countries and their individual parts is very different, being directly dependent on the nature of settlement, the size and density of the population.Major cities and urban areas have a higher density than, for example, rural areas.Therefore, in some cases, use of the term "average population density".Calculated by dividing the average density of the total number of people (continent, country, state, region) in the area, expressed in square kilometers.If you convert to the above formula, we get the expression: P. n.= P / Q.
greatest population density, not in China, which has gone down in the adage, and in Monaco.According to the latest data, in the principality of 16,500 people. / Km².China is the only place on 55, with a density of 141 persons. / Km².In second place - the Republic of Singapore (7326 pers. / Km²).The lowest density of Nunavut.Here per square kilometer only 0.02 a person.
Russia on the list is in the 180th place.Here, the average population density is 8.5 persons. / Km².In more than half of the country's area (and that Siberia and the Far East) per square kilometer only three people.Settling in these areas patchy.The vast uninhabited spaces - Tundra, marshy average, southern and mountainous taiga, where conditions are almost uninhabitable.In some autonomous regions (Yamalo-Nenets, Evenki, Chukchi, and others.) Density and even lower - 0.03 / km².
highest population density in the capital and the region.In Moscow itself the approximate density of 325 persons. / Sq km in area, except for Moscow - 141 attendees. / Km².
Interestingly, the larger regions (area) density is lower.The area of the central economic area 483 square kilometers, and the density - 62 people. / Km²;West Siberian area - 2427 square kilometers, the density - 2.5 persons. / km²;Far East area - 6215 square kilometers, the density - 1.5 persons. / km².
These differences are explained by the socio-economic, historical, natural and geographical factors.In the central regions of the country have been laid before the trade routes, there was communication with other countries.This is where concentrated populations, developing industry economic systems aimed at the processing of the same and imported raw materials.But the main factor, perhaps, is still the climate: the more it is suitable for human life, the higher the population density.
weak development of the North, Siberia and Far East due, as has been said, natural factors geographic: orographic complexity and too harsh conditions do not allow to develop the infrastructure to a high level.
Russian government launched the fight against overpopulation, presenting a program of so-called "labor mobility".The idea of something like a Komsomol construction of Soviet times, when young people were sent to the lifting of virgin land, and where along with the advanced workers and military prisoners.A striking example is the BAM.I wonder what will the old way?Under the program, unemployed people who moved in 2012 from the densely populated cities in the undeveloped regions and depressive receive up to 120 000 rubles.Perhaps, very soon we will be able to observe mass migration and a sharp change in the density of population ...
