“…The results of much research confirm the impact of many different socio-demographic factors, for instance: age, education, income, wealth, employment status and occupation, stages in the life cycle and marital status (Aren & Aydemir, 2015;Barasinska & Schäfer, 2018;Kumari, Satya, & Kritika, 2018).
