Ill-health reduces the individual citizen's quality of life and also entails large costs for society. Many health determinants can be influenced by political decisions and individual choices. For several reasons it is therefore important to be able to describe and analyse the evolution of the population's health, lifestyles and living conditions. To enable this we need surveys and studies that follow the long-term evolution of public health and its determinants.
The results of these studies are available at the agency's website in the form of statistics, tables, graphs and maps. In addition to health, lifestyle and living conditions, the statistics are in many cases broken down by age and gender and – when data allows – also by ethnic or cultural background, socioeconomic status, sexual orientation, LGBT identity, and disability.
The national public health survey
The national public health survey is a national study on health, lifestyle and living conditions. The study has been conducted annually since 2004 and comprises a random sample of 20,000 individuals aged 16–84 years. The aim is to show the population's state of health and to monitor changes in health over time as a part of a follow-up of public health policy. The study is an ongoing collaborative project between the Public Health Agency of Sweden and the Swedish regions and county councils.
