GÅS started in 2001 and is one of four sub-projects in the national project "The Swedish National study on Aging and Care" (SNAC). The study's aim is to investigate what future needs for care will look like and gain increased knowledge of the importance of the environment, lifestyle and past illnesses for the health and well-being of the elderly, identify risk factors for illness, and be able to relate the elderly's needs. The sample is made up of individuals aged 60 to 93 in the five municipalities in Sweden: Malmö, Hässleholm, Osby, Ystad and Eslöv. Participants who are 78 years of age or older are followed up every three years, while for those aged 60 to 72, follow-up will take place every six years. During the years 2001 to 2004, almost 3,000 people participated in the very first survey round.
