Individual datasets that do not belong to any series.
This dataset charted Finnish consumption of alcoholic beverages in terms of individual drinking occasions. The data were collected as part of the Finnish Drinking Habits Survey 2016 (main data: FSD3282). FSD's holdings also include a dataset belonging to the same study concerning abstaining from drinking during occasions where other people consumed alcohol (FSD3314).
The study examined situations in which the respondents had consumed alcoholic beverages: how many centilitres they had consumed of different alcoholic drinks, where, when and with whom. The respondents could provide information on multiple drinking occasions, and the same questions were asked about each of them. The data also contain conversions made from variables in the questionnaire, e.g. conversions of consumed quantities of different drinks into pure alcohol. The questionnaire (in Finnish) describes in more detail the coefficients used in the conversions as well as the formula for calculating the respondents' estimated blood-alcohol content (per mille) during each drinking occasion.
Background variables include gender, age, date and weekday of the drinking occasion as well as starting and ending times for drinking.
The stratified sample of 3,870 persons was randomly selected from the population register maintained by Statistics Finland in August 2016. The first stratum included persons aged 18 - 29 (stratum size 1,233) and the second persons aged 15 - 17 and 30 - 79 (stratum size 2,637). The first stratum is proportionately larger in size (persons aged 18 - 29 were twice as likely to be picked for the sample as persons belonging to the other stratum), because non-response is common in this age bracket.
The gross sample of 3,870 persons includes overcoverage of 47 cases (deceased, permanently institutionalised or moved abroad). The net sample thus constitutes 3,823 persons. The participants were sent an information sheet regarding the study beforehand with an accompanying letter. In total, 2,285 valid interviews were conducted. The interviews were conducted face-to-face with the exception of 159 telephone interviews. In connection with the interview, the participants were given a drop-off questionnaire which they filled out and gave to the interviewer in a sealed envelope. The interviewers mailed these envelopes to the organisation which collected the data. Statistics Finland supervised the legitimacy of the data collection process. In total, 2,150 drop-off questionnaires were received.
