Statistics such as the size of hard-to-enumerate populations
are both important and difficult challenges for social science:
important in that they represent one area where sociological
results impact the allocation of public funds for both law enforcement
and public health resources (Aceijas et al., 2006,
Dengenhardt & Hall, 2012), yet difficult because they often
require estimation procedures that pit ideal methods against the
difficulties of research implementation. Such questions lie at
the heart of applied sociology
