Herewith article is an example of applying of some quantity method to analyse changes in town settlement network within the framework of a region. This region compreses Bydgoszcz voivodship within bounds before administrative reform in 1975. The area that composed Bydgoszcz voivodship when the war was over, belonged to the territory supplied with a danse, previously formed network of towns and a high percentage of a town population. Dynamic increase of regional economy, its industrialization undoubtedly influenced upon the further rate of urban process i.e. upon a system of town settlement. An attempt to answer the following questions was undertaken, while analyzing the changes in town settlement in Bydgoszcz voivodship in 1946-1970: does an economic development of the region reflect in the town settlement network and what is the direction and size of these changes? How did the changes in settlement network influence upon the homogenity of a system as a whole and what was a dynamics of changes? Preliminary examination pointed out that in the period, mentioned above, the changes comprised mostly size and functional structure of the town network its density changed considerably less as a number of cities changed slighty. A process of concentration of population in the great towns such as Bydgoszcz, Toruń, Włocławek, Grudziądz, Inowrocław was evident. At the same time the numer of population in small settlements declined. Small towns counting 10-20 thousand inhabitants were found in a specific situation. A number of inhabitants has been increasing quite regularly as they developed town-creating functions. Moreover population emigrating from the countryside and the small settlements regarded these towns as „transitional statins” on the way to the greater centres. Diagram of dislocation in the rang of the towns in Bydgoszcz voivodship (diagram 1) served to analysis the changes in hierarchical system of units. Four types of towns developement were separated here: 1. Towns of permanent status 2. Towns of ununiform developement 3. Towns still developing 4. Towns loosing their rang Permanent status in this division belongs to the big towns while the remaining units often changed their position. This phenomena was usually connected with the development of industry or its shortage, administrative changes also influenced upon permanent status of these towns. Distribution of the towns accepted as a theoretical model accordingly the rule of sequence and size (Zipf rule) pointed out that the system of town settlement has been considerably changing due to economic development. Increasing quantity of contrast exponent „a” confirm and intensive process of population concentration in the big towns, at the same time a number of inhabitants of small settlements has been declining. Diagram pointed out a gap in settlement system within the towns of means size that could be interpreted as a staggery of homogenity in town settlement system. Calculation of the exponent „a” mentioned above allowed to confirm that the process of changes in the town regional system was more intensive in 1946-1960 than the next period. This conclusion acknowledges a strict correlation between a dynamics of economic developement and the changes of the town settlement network.

The article is an attempt at typological presentation of the demographic structure of the Suwałki Province and its spatial differentiation. In contains comments on the reasons of the differentiations and indicates further consequences of the processes of changes in biological structure of the population of the Suwałki region. The data for the year 1975 were utilized in the research since full statistical documentation exists for that period. Community and town were accepted as basic spatial units. In the first part of the article, the choice of typological methodology based on F. Uhorczak typograms methodology based on F. Uhorczak typograms was explained. Subsequently, the basic demographic features of the population of the Suwałki Province, which are the basis of the analysis, were characterized. The features were presented by means of the following ratios: 1) birth - rate, 2) proportional participation of the population having non – agricultural maintenance sources - economic ratio of urbanization, 3) participation of population of retirement age in the total number of population - ratio of population ageing, 4) number of women per 100 men - feminization ratio. Basing on mutual relations of the features, six types of demographic structures were distinguished, which showed distinctly the existing biological – social differentiation of the population of the region. The most favourable types of demographic structures occur in the western and central parts of the Suwałki Province, where there is a high share of younger age - groups in the structure of the population age, more even structure of the sexes and relatively higher level of urbanization. The eastern areas, on the other hand, appear to have decidedly worse demographic structure - lower birth-rate, higher level of population ageing, lower level of urbanization, strongly deformed structure of the sexes with clearly marked dominance of men (particularly in the country) which may negatively influence the processcs of natural movement in the future.

A transformation of relations among the factors of agricultural production: land, labour and production means, is taking place in the suburban zone of Warsaw, to the detriment of land. The area of agricultural land is decreasing due to change of the type of use by turning land into various forms of non-agricultural use, including especially housing and industrial construction, and transport investment projects. This decreasing tendency of the area of agricultural land is accompanied by increasing specialization of agriculture, mainly in the direction of vegetable-fruit-and-flower production (including horticultural production of protected crops), in which optimum acreage of a farm, given intensive cultivation, could be small. Simultaneously, greenhouses, hotbeds and foil tunnels give the space of smaller towos and rural areas the specific aspect of suburban landscape.
