Sample

 

Based on probability samples in all participating countries, SHARE represents the non-institutionalized population aged 50 and older. Spouses are also interviewed if they are younger than 50.

Table 1 shows the breakdown of all wave 1 2004 samples (Release 2) by country, sex, and age. It also displays the household response rates and the individual (i.e. within-household) response rates. The household response rate of the samples supported by the original funding from the European Commission’s 5th framework programme is 63.3 percent.

With the release of wave 2, SHARE went into its longitudinal dimension, with new possibilities for data analysis when exploring variation of the same people over time. While the focus has been on re-contacting respondents from the first wave, a “refresher” sample was also drawn in all first wave countries except Austria and the Flemish part of Belgium. For the refresher sample the same sampling methods were used as in wave 1, only cohorts born in 1955 and 1956 were oversampled to keep the sample representative of the population 50 years old and older.
