Abstract

The intensity of changes in the population dynamics of the Early Neolithic (ca. 6250–5300 cal BC) communities in the Central Balkans was addressed by estimating the growth rate values. The Bayesian approach (Crema and Shoda 2021) of estimating intrinsic growth rates by fitting different models of population growth was applied to radiocarbon dates from the Early Neolithic sites in Serbia. We explored two possible episodes of population growth based on the results of the population dynamics reconstruction using the summed calibrated radiocarbon probability distributions (SPD) method. The results have shown that, within the first episode of growth, the intrinsic growth rate mean values are higher than the estimated continental average (between 1% and 2%). The results indicate a sudden and fast rise in population size, possibly due to the influx of the new population settling in the region at the beginning of the Neolithic. Lower values for the second episode could indicate more gradual population growth due to the mechanisms associated with the Neolithic Demographic Transition and the rise in fertility.

研究史前人口动态变化的强度:新石器时代早期中巴尔干地区人口增长率的估算
通过估算增长率值,研究了巴尔干半岛中部新石器时代早期(约公元前 6250-5300 年)族群人口动态变化的强度。我们将贝叶斯方法(Crema 和 Shoda,2021 年)应用于塞尔维亚新石器时代早期遗址的放射性碳年代,通过拟合不同的人口增长模型来估算内在增长率。根据人口动态重建的结果,我们使用总和校准放射性碳概率分布法(SPD)探讨了两个可能的人口增长事件。结果表明,在第一个增长期,内在增长率的平均值高于估计的大陆平均值(1% 到 2%)。结果表明,可能是由于新石器时代初期定居在该地区的新人口的涌入,人口数量突然快速上升。第二个阶段较低的数值可能表明,由于与新石器时代人口转变和生育率上升相关的机制,人口增长更为渐进。

期刊介绍: Radiocarbon serves as the leading international journal for technical and interpretive articles, date lists, and advancements in 14C and other radioisotopes relevant to archaeological, geophysical, oceanographic, and related dating methods. Established in 1959, it has published numerous seminal works and hosts the triennial International Radiocarbon Conference proceedings. The journal also features occasional special issues. Submissions encompass regular articles such as research reports, technical descriptions, and date lists, along with comments, letters to the editor, book reviews, and laboratory lists.
