Wpływ czynnika ekonomicznego na zachowania prokreacyjne rodzin rolników indywidualnych

Abstract

The work attempts at estimating the effect of the economic factor on procreational attitudes of families of individual farmers. The factor was symptomatically defined by adopting: the area of a farm in ha, assessed income in thousand zł, value of agricultural products sold in thousand zł, and a size of living quarters in rooms and m2. The stated task was to be fulfilled with the aid of all-Poland survey done by The Department of Statistics and Demography of Academy of Economics in Poznań, as of January 1,1980. A population of 674 families of individual farmers inhabiting the central-western macro-region is the subject of analysis. The effect of economic factor on procreation in families is examined by means of the cohort analysis with the aid of methods of analysis of correlation, straight regression and curvilinear regression. The results indicate that there is no statistically significant linear relationship between procreational behavior of the examined families and the size of a farm, value of products sold and the assessed income. On the other hand a negative linear relationship was observed between the family size and apartment conditions in the first year after matrimony, at the moment of observation the correlation is positive with the exception of cohorts 1945-49, 1970-74. The study revealed that the examined relations do not have a linear form. The parameter yx is significant for the relation of family size to value of the products sold for the cohort 1960 - 64 and to the size of the farm for cohorts 1945 - 49, 1950 - 54. The regressive analysis allows to formulate the view that a shape of correlational relationship between family size and the economic factor changes with the period of establishing a family.
