Supplementary information about number of participants
The number of participants are dependent on how many persons from the LNU sample has survived to old age. In 2011, the SWEOLD sample was complemented by an additional representative sample of the Swedish population aged 85–99. This additional sample allows for more detailed analyses in smaller age and sex subgroups for those over 85 years of age.
Supplementary Information
The SWEOLD sample was initially designed based on an existing nationally representative sample of the total adult population in Sweden – the Swedish Level of Living Survey (LNU). SWEOLD comprises those persons previously included in the LNU sample who have passed the LNU’s upper age limit of 75 years (in 1992, 2002, and 2011) or 69 years old (in 2004 and 2014), and are still living in Sweden at the time of the survey waves, with the exception of the first survey wave that was restricted to persons who had previously been interviewed at least once in any of the previous LNU surveys. The data waves represent sequential, repeated, cross-sectional surveys.

Supplementary Information
SWEOLD participants were identified through the Swedish Level of Living Survey (LNU), a random sample of 1/1000 of the Swedish population aged 15 (in 1991, the lower age limit was raised to 18 years, and in 2000 to 19 years) to 75 years. A random sample of young people and immigrants is continuously added to the original LNU sample to get a representative sample of the total population aged between 15 (or 18/19) and 75 years. The sample is obtained using the identification numbers issued to all Swedish residents by the state. SWEOLD participants are LNU-sampled individuals having passed the age of 75 years old (in 1992, 2002, and 2011) or 69 years old (in 2004 and 2014).
