Sažetak
Sex ratio at birth has been one of the most studied demographic phenomena, yet remains one of the most poorly understood. Numerous physiological, ecological and demographic factors seem to influence sex ratio at birth, but there is no single, indisputable explanation. Certain countries show trends in sex ratio at birth over time, and their sex ratio at birth time-series can be modeled by non-random stochastic processes that reflect interdependency in subsequent annual observations. This article examines sex ratios at birth in the Republic of Croatia from 1946 to 2007. Time-series assessments were performed, as well as autoregression modeling. The Croatian time-series is the product of a pure random process with no observable time trend despite the presence of those factors known to affect sex ratio at birth. The size of the live-birth population may not be sufficient to reflect the subtle changes in these factors. The prospective study will conclude whether the randomness of the series is a universal feature of small populations.
