Although trafficking in human beings was criminalized in Spain in 2010, data on this phenomenon are scarce and incomplete, consisting only of cases formally identified by police as having a very clear bias to trafficking for sexual exploitation. In an effort to increase empirical understanding, in 2019 we undertook quantitative research by gathering information on cases detected during 2017 and 2018. A questionnaire was distributed online to 757 stakeholders who could potentially have come across victims of trafficking. The 150 responses obtained provide valuable information about the number of victims, their profile, the dynamics of trafficking and the types of exploitation they suffered. The number of victims detected during the research period (n = 7448) is far higher than those officially identified (n = 458), which indicates that official cases may represent only the tip of the iceberg and point to the necessity of adopting measures to improve the identification system. Findings also show differences in victims’ profiles, victimization dynamics and forms of exploitation depending on the type of trafficking that could be taken into account when designing intervention and prevention programmes in this matter.

尽管2010年西班牙将贩运人口定为刑事犯罪，但有关这一现象的数据很少且不完整，仅由警方正式认定为以性剥削为目的贩运人口的案件非常明显。为了增加对经验的理解，我们在2019年通过收集有关2017年和2018年发现的案件的信息进行了定量研究。已向757个利益相关者在线分发了调查表，这些利益攸关者可能会遇到贩运活动的受害者。获得的150份答复提供了关于受害者人数，他们的概况，贩运动态和遭受的剥削类型的宝贵信息。在研究期间发现的受害人数（n  = 7448）远远高于正式确定的受害人数（n  = 458），这表明官方案件可能仅代表冰山一角，并指出必须采取措施改善身份识别系统。调查结果还显示，在设计有关此事的干预和预防方案时，取决于贩运的类型，受害者的概况，受害动态和剥削形式会有所不同。
