In the first half of the 19th century, the parish of Tinjan was under the rule of the Austrian Habsburgs. The Habsburg reign was shortly interrupted by a period of French rule which ended in 1813. The parish of Tinjan had a distinctive rural character and at the beginning of the 19th century it had numbered 1200 inhabitants. By the end of the half of the century the population grew by 31, 4%. This work is based on the analysis of the registers of births, marriages and deaths in the period from 1800 to 1850, and it deals with the particular elements of demographic behaviour in the parish of Tinjan. The registers include data about phenomena such as high birthrate, low average life expectancy, high infant mortality rate in times of crisis, mortality caused by epidemics and hunger. This data indicates that the population at the time was still in the pre-transition period, despite lower rates of mortality in some ten-year stage. Moreover, this work analyses data on the gender structure of the population in Tinjan. The data show that there has been a larger number of baptised, however, also deceased male children. Furthermore, based on the seasonal variation of the weddings it is evident that the population of the parish of Tinjan obeyed the strict catholic rules imposed by the Church. The registers of deaths were used for the analysis of the most common causes of death in the parish of Tinjan for certain age groups. The demographic indicators mainly do not differ from other Istrian towns in the observed period, however, all similarities and differences concluded on the basis of data during the research, are also mentioned in the work.
