c Size of municipality was classified as residential areas based on population sizes and categorized into rural (< 5,000), town (5,000– <20,000), medium-sized town (20,000–< 100,000) and metropolitan areas (≥ 100,000).

d Categorisation of socio-economic status was based on an index, which was calculated using information regarding education and occupational qualifications, occupational status and net equivalent income of the parents. More details are given in the Supplement.

e Media consumption was categorised as high, middle or low based on an index. More details are given in the Supplement.
