The effect of the change in air temperature on the number of newborns in Vienna 1984-99.
The number of daily births depends on a wide range of sociodemographic, temporal as well as many other mostly unknown factors, resulting in non-random patterns. We tested the hypothesis of the influence of the change in air temperature on the daily number of all newborns in Vienna (n=254 797) in the period 1984-99 (n=5843 days). We found a significant association of sudden changes in temperature with the daily number of births. The observed effect is responsible for up to 0.27% of the explained variation in the regression model.
