[The analysis of seasonality in births and deaths].
"Monthly data on live births and stillbirths and quarterly data on mortality and infant mortality in Poland are analyzed for the period 1983-1985.  The aim is to evaluate and compare seasonal fluctuations in these variables in Katowice voivodship and in Poland as a whole.  Effects of seasonal factors are estimated separately for males and females and urban-rural areas via a regression model. For births, effects of seasonality are similar in Katowice and Poland, while for deaths significant differences are observed.
