Abstract
Sex ratio at birth has been one of the most studied, yet most
poorly understood demographic phenomena. Numerous
physiological, ecological and demographic factors seem to
influence it although an unequivocal explanation is lacking.
Indeed, some countries have exhibited a trend in the sex
ratio at birth over the years. Their sex ratio at birth time-
-series can be modeled with the non-random stochastic
processes which reflect the interdependency in the
subsequent annual observations. This article examines sex
ratio at birth for the Republic of Croatia during the years
1946 to 2007. The tests for assessing the time-series were
performed, along with the autoregression modeling. The
Croatian time-series is the product of a pure random process
with no observable time trend despite the presence of some
factors known to affect the sex ratio at birth. It is suggested
that the size of the live-birth population is not great enough
to reflect the subtle changes in these factors.
