“…Previous studies have resorted to varying strategies, such as sampling from population or foreigner register data, Random Digit Dialling (RDD) (Schaeffer et al, 2011), surname sampling from telephone directories (Ersanilli & Koopmans, 2013), Respondent Driven Sampling (RDS) (Carling & Jolivet, 2017), snowball sampling, intercept-point sampling (McKenzie & Mistiaen, 2009), cross-national snowball sampling (Güveli et al, 2017), and online convenience sampling (Balter & Brunet, 2012;Potschke & Braun, 2017).
