General

Population density was obtained from the 2004 release of LandScan data, with a square kilometer resolution. These data served always as a base for any infrastructure placement, as long as given infrastructure availability is correlated with the population density.


Statistical data such as the age and gender distributions in the society, as well as the distributions of households, workplaces, schools, etc were obtained from the National Census Bureau, in particular from Polish Regional Data Bank. The available age and household data was in the voivodeship resolution, the information concerning the numbers of schools was given for each commune.


Statistical Poland

Population and the number of women and, as well as the number of households are given in Tab.1.

tab.1
Population statistics
Population 38.2 x 10^6 Households 13.3 x 10^6
Women 19.7 x 10^6
Men 18.5 x 10^6


The administrative hierarchy of Poland is the following. The highest level belongs to voivodeship, which, following the European Nomenclature of Territorial Units for Statistics (NUTS) is classified as NUTS-2. There are 16 voivodeships in Poland. Second level constitute about 380 poviats (NUTS-4). The lowest level in the NUTS hierarchy is a commune (NUTS-1). There are about 2500 communes in Poland. There are several types of communes, but basically only three appear in Poland:

Fig.1
  • urban/city communes (areas of larger cities)
  • village/rural communes (area comprising several villages)
  • city-village (urban-rural/mixed) (area comprising one smaller city and several villages)


The distribution of these 3 types of communes in Poland is presented in Fig.1. One can see that the total area of city communes is order of magnitude smaller than the total area of rural communes and about six times smaller than the total area of mixed communes. The corresponding numbers are given in Tab.2.

tab.2
Commune type Population Area [km2] Population density [km-2]
urban 20.3 x 10^6 15307 1328
rural 9.7 x 10^6 198457 49
urban-rural 7.8 x 10^6 99586 79


Most of the results presented here will be given in communal or poviat resolution. Mostly populated are of course cities. However, some regional population density characteristics are also visible in Poland. Figs.2a,b present the population density in Poland per commune or poviat, respectively. Another, though similar look give Figs.3a,b also in commune or poviat resolution, respectively. They show the area fraction covered described by low population density. By low we mean here population density less than or equal to 0.3 of average population density in given unit (commune or poviat). The average population density was calculated over the commune (or poviat) area, where population density data was given per square km.

From Figs.2 one can see there are very "population" characteristic regions. North-East and Nort-West part of Poland has a very low population density, also these are mostly rural or urban rural communes. The highest population density is visible in the middle of the country, where the capital city is located, and in the southern regions, were highly industrial Slaskie voivodeship is located.
