The paper „Life in Pazin in the second half of the 19th century according to the baptismal, marriage and death register books“ analyses the period between 1850 and 1870 using the baptismal records from 1847 to 1882, marriage records from 1847 to 1912 and death records from 1847 to 1909. The baptismal register book has served for the analysis of the annual difference in the numbers of baptised children in Pazin, the seasonal variations of baptisms and conceptions, the number of midwives and priests who conducted the baptisms, the gender structure of the baptised children, the number of legitimate and illegitimate children, the naming convention, the frequent surnames in Pazin, the professions of the parents and godparents, their nicknames and social status and the influence of those two factors on the selection of godparents. The analysis of the marriage register book shows the age structure of newlyweds in Pazin, the number of widowers and widows, the age difference of the bride and groom upon entering marriage, seasonal variations, preferred days in the week to enter marriage, frequent places of origin of the newlyweds and the most frequent witnesses at weddings. The paper also lays out data obtained by analysing the death register book in order to ascertain the gender and age structure of the deceased, the common causes of death, average age and the years of great epidemics. The data gathered from all of those books have been analyzed and compared with those for other places in 19th century Istria to determine the similarities and differences between Pazin and other places in Istria.
