1. Method of the Consumer Survey

The Consumer Survey is a telephone interview survey by means of which it is possible to measure Finns’ images - assessments and expectations - of the general economic development and the financial situation of one's own household, and intentions to make major purchases, save money or take out a loan. In addition, the survey is a tool for finding out how common modern equipment are in households. For the Consumer Survey, answers are given by means of answer options (qualitative survey).

The first Consumer Survey interviews were conducted in November 1987. Until 1991, the survey was carried out twice a year, in May and November. In 1992, the survey times increased to four: the survey months were February, May, August and November. Since October 1995, the Consumer Survey data have been collected monthly on assignment and partial financing of the European Commission.

The population of the Consumer Survey comprises 4.5 million persons aged 15 to 84 and their 2.6 million households in Finland. A sample of 2,350 persons is drawn for the survey for every month. The same sample is also used for the data collection of the Finnish Travel Survey. The target area is the whole country and the respondents of the survey represent the population in Finland, according to age, gender, region of domicile and native language.

The interviews of the Consumer Survey are conducted from Statistics Finland's Telephone Interview Centre (CATI) during the first two or three weeks of the month. In September 2016, in all, 1,202 responses were gained, so the non-response rate of the survey was 48.9 per cent (incl. over-coverage). The non-response rate includes those who refused from the survey or were otherwise prevented from participating, as well as those who could not be contacted.

The response data of the Consumer Survey are expanded to the whole population with weighting coefficients. Weighting corrects the effects of non-response and improves the statistical accuracy of the data. The weights are established by using a calibration method and the probability of each observation to be included in the sample. The figures and series presented are not seasonally adjusted.
