One of the questions was whether respondents had consulted their GP at least once a year. Another question was whether they had consulted a medical specialist or physiotherapist. If one of the questions was answered affirmatively, there was a follow-up question about the frequency of the contact. The data are based on the health module of POLS. The annual sample survey comprises approximately 2,500 persons. Residents of homes and institutions have not been taken into account. As the figures are based upon a sample survey, they are subject to a margin of error.
