As every other empirical study, the Saxon Longitudinal Study also has certain methodical particularities, that must be taken into consideration when interpreting the results.
- The sample consists of age-homogenous group of East German adults, exclusively from the state of Saxony (regions around Leipzig and Chemnitz).
- The education level of the sample is relatively high. All participants have at least graduated from the 10th class of “polytechnische Oberschule”.
- The results of the study cannot necessarily be generalized to the total population of East Germany (due to different age groups, different federal states, other education levels etc.).
- The response rate has decreased over the years. Based on the N = 587 people that in 1989 expressed their willingness to continue contributing, in 2019/20 the response rate was as high as 54.7%, after more than 32 years of study. Based on the number of participants whose addresses are classified as active, (not deceased, not unknown relocated, etc.) the response rate is 75%.
- The reasons for not participating/ dropout of individual participants is unfortunately not always known, and, despite all the effort, also cannot always be determined.
- With participation numbers of approximately N=300 subgroup analyses are not always possible (e.g. women of a certain income group).
- Even with longitudinal studies, the changing of participants in the different survey waves leads to sample limitations, since many of the participants did not continuously take part in all surveys.
- There are no/ very few similar data from West Germany that examined similar questions over a long period of time in a comparable cohort.
