In 1999, the Swedish Ministry for Social Affairs promoted and supported a national project aimed at monitoring and evaluating the care-of-the-elderly system in Sweden. To achieve these aims, four longitudinal, individual-based data collections describing the ageing process and encompassing the care system as a whole, were initiated. This project was named The Swedish National Study on Aging and Care (SNAC). SNAC-K is one of the four sub-projects included in SNAC. The ultimate goal of SNAC-K is to understand the ageing process and to identify possible preventive strategies to improve health and care in elderly adults.


Two parts: Population and care services system. The study design, builds upon the joining of two perspectives: The population perspective and The care system perspective. Population perspective In the population part of the SNAC-study, a large, representative panel of elderly in different age cohorts from 60 years and above is followed over time in order to record the development of personal characteristics, as well as social and economic circumstances. Care system In the care system perspective, there is a systematic, longitudinal, individually-based collection of data concerning the operations of the long-term care system - volume and character of services provided in relation to needs and dependency, costs, staff input, etc.

Longitudinal population study with continuous recruitment of new cohorts with follow up examination after six years for the age cohort 60 – 72 and each third year for the cohort 78 – 100 years of age.

Four different regions of Sweden are covered: Snac-Kungsholmen/Stockholm, Snac-Nordanstig, Snac-Blekinge, Snac-Skåne.

Individuals aged 60 – 72 and 78 – 100.

At present most of the information about the functioning of the system of long-term care for the elderly is provided by cross-sectional statistics and studies directed towards different parts of the system. The official statistics cannot answer the fundamental question of how resources are allocated according to needs. Also, most current research studies concerning the elderly are cross-sectional. Studies of the system of long-term care relate as general only to a part of the system and are based upon an organisational perspective. The possibilities to use this information for analysing how needs develop from a broad perspective and how they are met are very limited. There is, thus, a need for individual-based longitudinal studies that describe the ageing process from different aspects - the development of health, functional and cognitive ability, social and economic situation, etc. - and that encompass the care system as a whole including all levels and forms of long-term care, geriatric, as well as social, public and private or voluntary, and formal, as well as informal.



Good options to link to other data set due to use of personal identification numbers-ID.

Data quality

No major entry errors.

No major changes.

High level of consistency.


The strengths of the SNAC-study are its cross-sectional approach, the regional profiles and that it can add knowledge to information available in registries. Available information does not specify times of data collection and design. The basic idea behind SNAC is that for a long time (30 years or more) make a sectoral individual-based data collection, as well as describing the aging process, health and appearance of the care needs of the social, medical and psychological point of view, and record the efforts that individuals receive from municipal elderly care and county health care. Even data that highlights the efforts relatives and NGOs doing collected. The data are organized in a longitudinal database.
