population. These settlements experience stronger and stronger functional transfor-
mation because of expansion of the industrial firms. According to the mentioned
model, more and less intensely urbanised settlements and rural settlements have
been separated. All settlements that do not meet the mentioned criteria in the model
have been included in a separate group. Status of town gained the settlements with
over 2,000 of inhabitants, below 10% of agricultural population, and with over 50%
of workers in place of living, although it has less than 10,000 inhabitants. After
adoption of the spatial plan of Bosnia and Herzegovina in 1991, a very broad process
of preparation of spatial plans for municipalities was opened and a certain number
of spatial plans for special areas were prepared as well (Fig. 15.3 ).
Apart from Sarajevo, the leading centres of polarisation are also the macro-
regional centres of Banja Luka, Mostar and Tuzla, of which these towns are
functional foci. Similarly, even more expressed disproportion between number of
population, investments in long-term property and number of employed people is
also present at the regional level. Thus, according to demographic concentration
and investments, four regions are distinguished in spatial plans: Sarajevo, Mostar,
Banja Luka and Tuzla. At the same time, a positive correlation between the analysed
indicators of polarised development of the regions and demographic development of
the main core settlements is obvious. So the leading centres of the regions prevalent
in polarisation of population and functions in most cases are the demographically
developed regional centres. By polarised development of population and function,
