Background. We have studied human life expectancy in Croatia. Materials and Methods. Local daily papers reported obituitairies for 447 men and 366 who died in a month period. The data were analyzed with the median derivative power function model. Results. The median age of death was 76 and 81 years for men and women, respectively. Cummulative mortality increases at a constant rate after the age 60 y and 65 y for men and women, respectively (r2 = 0.99 and 0.98). Conclusions. Individual life span is a stochastic (random) biological event within the deterministic frame of cumulative mortality.
