Since random walking does not ensure the sample is a reflection of the entirety of the population (the number of the female and elderly respondents was higher than the national average), the sample of the people was corrected by multi-dimensional weighing factors (gender and age) (Grafen & Hails, 2002).
After these methods were applied, the sample was representative of the structure of the Hungarian population in all the four aspects (region, type of settlement, gender, and age).
