TwinLife

Information for researchers

We re-structured the TwinLife homepage, and we stopped maintaining the English version, as this page is mainly adressed to the participants and the German-speaking public. For the scientific community, we installed an English data documentation website, where all important information about Twinlife can be found. Up to date, this site is still under construction, but it will provide all the information you need soon.
In the following, here is some brief information about TwinLife for you. Clicking the headings will open the content.
What is TwinLife?
TwinLife is a 12-year representative behavior genetic study investigating the development of social inequality.

The long-term project has begun in 2014 and surveys more than 4,000 pairs of twins and their families regarding their different stages of life on a yearly basis. Not only social, but also genetic mechanisms as well as covariations and interactions between these two parameters can be examined with the help of identical and fraternal twins.
In order to document the individual development of different parameters it is important to examine a family extensively over the course of several years. Six important contextual points are focused on: Education and academic performance, career and labor market attainment, integration and participation in social, cultural and political life, quality of life and perceived capabilities, physical and psychological health and eventually behavioral issues and deviant behavior. The so collected data can give insight into questions concerning the development of social inequalities and will be made available to the scientific community.
