The Inka Empire (1400–1532 CE) made common practice of relocating individuals, households and entire communities throughout their expansive realm for different reasons depending on subjects’ assigned social status. Reconstructing patterns of residential mobility and both intra- and extra-regional mobility at Inka sites, particularly in the imperial heartland, could therefore permit some estimation of the social status(es) of their constituents, and thereby provide bottom-up insights into Inka statecraft and political economy. However, this is a difficult endeavor using only archaeological lines of evidence. This study presents oxygen, strontium and lead isotopic results from archaeological human remains (N = 81) from the site of Patallaqta, near Machu Picchu in the Sacred Valley of the southern Peruvian highlands. Isotopic data are used to reconstruct patterns of immigration at the site, which are in turn used to estimate the social status of the population. The resulting ⁸⁷Sr/⁸⁶Sr show moderate variation, with most individuals clustering within a range higher than the estimated values for the locale, while ^206,7,8Pb/²⁰⁴Pb results show greater variation spanning multiple Pb isotope provinces, and δ¹⁸O results cluster broadly around estimated local water values. Taken together, these results are consistent with the expected distribution of groups drawn from communities within the vicinity of the Sacred Valley and possibly the Peruvian or Bolivian altiplano. These results are in notable contrast to published isotopic results from the nearby site of Machu Picchu, and suggest distinct compositions among the resident populations of each site. This study provides further insights into the intersection of residential movement and status dynamics in the Inka Empire.

印加帝国（公元1400年至1532年）出于不同的原因，根据对象分配的社会地位，将个人，家庭和整个社区迁移到整个扩展领域，这是一种普遍的作法。因此，在印加遗址，特别是在帝国心脏地带，重建居民流动性以及区域内和区域外流动性的模式，可以允许对其构成者的社会地位进行某种估计，从而提供对印加治国之道的自下而上的见解。和政治经济学。然而，仅使用考古学的证据，这是困难的努力。这项研究提供了秘鲁南部高地圣谷马丘比丘附近Patallaqta遗址的考古人类遗骸（N = 81）的氧气，锶和铅同位素结果。同位素数据用于重建现场的移民方式，进而用于估计人口的社会地位。所结果的⁸⁷ SR / ⁸⁶锶显示适中的变化，其中大多数个体的范围内聚类比的区域设置的估计值越高，而^206,7,8铅/ ²⁰⁴铅结果表明更大的变化跨越多个铅同位素省，和δ ^18个ö结果大致围绕估计的当地水价集聚。综上所述，这些结果与圣谷附近社区以及秘鲁或玻利维亚高原居民的预期群体分布相符。。这些结果与附近马丘比丘（Machu Picchu）站点发表的同位素结果形成鲜明对比，并暗示了每个站点的常住人口中的独特组成。这项研究提供了对印加帝国住宅迁徙与地位动态的交汇点的进一步见解。
