4.1 The data is collected for two purposes: compiling statistics, and research.
4.2 Personal data will be used to survey diseases and disorders in the population, investigate how these vary between different groups, change over time, and how they are linked to other diseases, disorders or risk factors.
4.3 The personal data will be used to survey known and potential risk factors (eg different living habits) in the population, and investigate how these vary between different groups, change over time, and how they are linked to diseases.
4.4 Personal data from the Hälsometer is supplemented with data of importance for health from various registers. This applies to data on gender, age, marital status, family status, number of children, own and parents' country of birth, citizenship (in groups), immigration year, migration background, area of residence, education, occupation, labor sector, income, food purchases via loyalty clubs, grants, sickness and activity allowance, old-age pension, sick leave, care, drug use and future causes of death. Since individuals' health is affected by heredity and family relationships, information is also included for parents as well as any siblings and children.
4.5 When the aforementioned data has been merged, these are anonymized (names and social security numbers deleted) before analyses are performed. The results are always presented at the group level where no individual's information can be interpreted.
4.6 CES creates various reports and fact sheets based on data from the Hälsometer and other sources. This applies, for example, Region Stockholm’s public health report (link: https://www.folkhalsoguiden.se/halsa-stockholm/). Data from the Hälsometer will also be used in the digital tool folkhalsokollen.se. These compilations and reports are used by Region Stockholm, as well as municipalities and districts in Stockholm County, to plan health care, urban planning and preventative initiatives to improve public health.
4.7 Apart from CES, data from the Health Survey may be analysed by external researchers. Disclosure of data to researchers requires an application with a research plan, ethics approval and confidentiality testing.
