Zróżnicowanie wyznaniowe a postawy prokreacyjne magnaterii w XVI i w pierwszej połowie XVII wieku

The article is an attempt to answer the question whether professed religious affiliation influenced the number of children in aristocratic Christian families and whether there were other factors with some impact on that demographic parameter. The analysis has been carried out on the database containing the numbers of children who reached adulthood in aristocratic families – 41 Orthodox, 40 Calvinistic and 89 Catholic – living in the Polish–Lithuanian Commonwealth (formally the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania) in the 16th century and the first half of the 17th century.
