Fig. 21. Life expectancy (e x ) is missing from the majority of the cemeteries because their graves were originally shallow and consequently destroyed during cultivation. Only those children's graves escaped destruction which were originally dug deeper. In case of the few populations given in Table 4 the researchers found the expected infant mortality rate in some instances but in others they discovered much lower ones. Thus in some of the cemeteries only a few while in others more children's graves became destroyed throughout the centuries. Thus the proportion of those between 0 and 4 years of age is important for demography because the mean length of life is based on it. In those cemeteries where the infant graves were not destroyed the expectation of life at birth is lower than those where the destroyed infant graves create the false impression of a low mortality rate. Of the cemeteries included in Table 4 the life expectancy of Halimba, Zalavár—Village and Kérpuszta are closer to reality. The 32-1 years calculated for Sárbogárd have to be consequently reduced by a few years and it is much more realistic to place it between 28 and 30 years of age. The normal age at death of the population of Sárbogárd is 55—60 years. This is the age reached by the majority of the population. The other series introduced show similar values. The particular demographic features of the population of Sárbogárd is especially clear from the mortality rates of adults. In Sárbogárd the males have an especially high death rate in comparison to the values for the females (Figure 21). As the result of the higher mortality rate of male, for example, the majority of the dead between 20 and 24 years of age are males in Sárbogárd while in the other five examined series the majority are females with the exception of Zalavár—Village (Table 4). In case of this latter, however, the mortality rate of males is only insignificantly higher than that of females in the mentioned age group. The difference between the mortality rates of the two sexes is naturally reflected in the values of the life expectancy of a twenty-year old. In Sárbogárd a 20 year old male has a life expectancy of 22-7 years, a rate which is much lower than the similar values of the introduced series, while the women of Sárbogárd have an expectancy of 33.5 years at 20 years of age, a figure which is higher than the similar values of modern India or Greenland. 37 From all these it follows that 50% of the adult male population of Sárbogárd reached an age of only 40 while 50% of the adult females attained an age of 55 (Figure 22). Such differences in the mortality rates of the adult individuals of the population of Sárbogárd allow us to compute that the resistance of males and females to injury causing death was much different.
