indeed i noticed a strange phenomenon in russia over all the birth rates are growing in vs in in vs in at the end of each of those years they went down slightly in for example i'll have to research this more to really see why this is but if i had to say now i'd say it is because of the new year and orthodox christmas as well as muslim kurban bairam celebrations november december january is when everyone is celebrating and partying not a lot of people are conceiving during this time
