Paleodemographic simulations are rare in the Maya region, because generally the skeletal collections do not represent well the ancient living population, are poorly preserved, and lead to flawed age-at-death estimations. The skeletal collection of Xcambó, however, is suitable for paleodemographic analysis and is large enough to enable comparison of paleodemographic trends between the Early (AD 250–550) and Late Classic (AD 550–750) periods. Three demographic simulations were generated; two relied on growth rates calculated from the site's previous archaeodemographic data, and a third simulation was based on a stationary scenario by applying Weiss's (1973) and Séguy and Buchet's (2013) models. All simulations indicate that Xcambó’s Late Classic population was growing faster than its Early Classic peers, with higher rates of survivorship and more severe mortality rates. We argue that the differences are more likely due to shifts in lifestyle and wealth than to environmental changes, as is confirmed by other bioarchaeological and skeletal indicators.

尤卡坦 Xcambó 的古人口模拟：北玛雅地区早期和晚期经典人口动态

古人口学模拟在玛雅地区很少见，因为通常骨骼收藏不能很好地代表古代生活人口，保存不善，并导致有缺陷的死亡年龄估计。然而，Xcambó 的骨骼集合适用于古人口学分析，并且足够大，可以比较早期（公元 250-550 年）和晚期经典（公元 550-750 年）时期之间的古人口学趋势。生成了三个人口统计模拟；两个依赖于根据该站点之前的考古人口数据计算的增长率，第三个模拟是基于应用 Weiss (1973) 和 Séguy 和 Buchet (2013) 模型的静止情景。所有模拟都表明，Xcambó 的晚期经典人口增长速度快于早期经典同龄人，具有更高的存活率和更严重的死亡率。我们认为，这种差异更有可能是由于生活方式和财富的变化，而不是环境变化，正如其他生物考古和骨骼指标所证实的那样。
