Well, not for Bavaria but another Catholic region with high illegitimacy ratios in those stats -- from books written in and from the stories of my own ancestors around the Habsburg Empire, it did appear to me that the typical profile of the mother of an illegitimate child is a maid or peasant girl who got in the sights of the landlord, and then had to struggle (either the mother all on her own, or the child was separated from the mother and given to relatives, or the father paid the mother without marrying her). 'Bastard' was a strong curse word, after all.

CATHOLIC ENCYCLOPEDIA: Illegitimacy

Until the year 1868, a man could not get a license to marry in Bavaria unless he possessed an amount of economic advantages that was beyond the reach of a large proportion of the population. Soon after the modification of this legal restriction, the birth rate of illegitimates dropped from twenty per cent to twelve per cent. The rate in Bavaria is still the highest in Europe, with the exception of Austria, but this is undoubtedly due in some measure to the unfavourable legal restrictions which yet remain, and to the surviving influence of the bad customs and the indulgent public opinion which were produced by the older regulations. That the large proportion of illegitimacy in Bavaria is not, as some have assumed, to be attributed to the Catholic religion, clearly appears from the fact that the evil is greater in the Protestant than in the Catholic sections of the country.

Well, Catholicism is better than protestantism.
