The Effect of Income of Fertility Rates in the Wielkopolska Region by Country During the Years 1999-2010

Abstract

Th e aim of this paper is to identify the size and diversity of changes to the fertility rate in the Wielkopolska region by county; namely the shape and strength of the relationship between fertility rate and income per capita in the districts of Wielkopolska. Th e study covers the years 1999-2010. It is based on data from the Regional Data Bank for the years 1999-2010 published on the website of the Polish Central Statistical Offi ce. To describe the dynamics of the fertility rate fi xed-base indexes were used; and to determine the impact of incomes on total fertility rate, a regression analysis on the correlation of two variables. Th e results of the study showed that during the period analysed, fertility rates in the region and its counties did not provide a simple reproductive model for the population. In the counties studied during the 2000-2010 period, the intensity and direction of fertility rates varied. Additionally, the hypothesis of a correlation between total fertility rate and income per capita was confi rmed. Finally, the estimated regression models of fertility rates relative to income vary according to the living environment.
