technique was used because the exact quantity of eunuch population is unknown.
is a technique where existing study subjects recruit future subjects from among their acquaintances.
procedure belongs to the group of ascendant methodologies characterised by its straightforwardness to reach participants who would otherwise be difficult to get (Van Meter, 1990).
uses a small pool of initial informants to nominate, through their social networks, other participants who meet the eligibility criteria and could potentially contribute to a specific study.
To reach this hidden population, the Council used a recruitment strategy called snowball sampling

RDS and other types of snowball sampling
make use of existing social networks.
is a non-probability strategy used in this study.
Besides, there are survey techniques available like respondent driven sampling (RDS), time location cluster sampling, snowball sampling
, capture recapture sampling and inverse sampling for estimation of hidden population or diseases which are rare in nature.
