The Swedish Level-of-Living survey is one of the longest running longitudinal social science surveys in the world. It was first conducted in 1968. Since then, it has been replicated in 1974, 1981, 1991, 2000 and 2010. A seventh wave - LNU 2020 - is currently (Feb 2021) completing its data collection phase. The original basis for LNU was a random sample of 1/1000 of the Swedish population between 15 and 75 years of age. LNU uses a multidimensional approach, covering individuals’ command over resources in terms of family and social relations, material living conditions (income and wealth), health, education, working conditions, political life, leisure time activities, housing conditions, etc. LNU has a panel design, meaning that the same respondents have participated in successive survey waves. As a complement to the interview data, information on income and some other resources has been collected from administrative registers. Starting in 2000, children age 10-18 living in the same household as the main respondent are interviewed about their living conditions in a broad sense, via an audio-questionnaire. Information from co-residential partners/spouses is also collected. Managers at LNU respondents' work places have been interviewed two times (APU, 1991 and 2000). In 2010, a separate study was also initiated, including a sample of individuals born abroad and their children (LNU-UFB). The LNU-project has gained both domestic and international attention and been highly influential within the scientific community as well as in the larger society. Documentation in English in the form of translated questionnaires are available for most survey years. For LNU-2000 and 2010, a codebook in English for the main sample and Partner-LNU is also available.
