“…Notably, there are a number of difficulties to more accurately estimating the prevalence of DMST/CSEC, whether point, period, or lifetime prevalence. Previously identified challenges include (a) the often hidden nature of this crime and hard-to-reach nature of trafficked minors; (b) reluctance among victims to disclose victimization, seek services, or participate in research because of fear (e.g., fear of retribution from traffickers, fear of law enforcement, fear of being identified as criminals), shame and stigma, lack of access to services, not self-identifying as a victim of DMST/CSEC, and a belief that they will not be believed or truly protected; (c) varying definitions of DMST/CSEC based on context (victims vs. law enforcement vs. industry) and scale (local vs. national); (d) lack of a uniform, centralized, and integrated system for tracking DMST/CSEC in part due to legal and policy barriers to the collection, sharing, and analysis of trafficking data; (e) lack of training and identification by law enforcement and service providers; and (f) challenges to collecting data from trafficked youth (e.g., informed consent from parents/guardians; concerns regarding further exploitation; and accessing potentially vulnerably youth who are homeless, in the foster-care system, or adjudicated; Barnert et al, 2017; Fedina & DeForge, 2017; Macias-Konstantopoulos & Bar-Halpern, 2016; Macias Konstantopoulos et al, 2013; Macy & Graham, 2012; Miller-Perrin & Wurtele, 2017; National Academies of Sciences Engineering and Medicine, 2020; Rafferty, 2008; Raymond & Hughes, 2001; E.
