The research project Generational Transmissions in Finland (Gentrans) is a longitudinal survey studying family transfers and interaction between two family generations. We conduct surveys on a representative sample of the “baby boomers”, or people born in Finland between 1945 and 1950 (initial sample 1,998 individuals), and their adult children (initial sample 3,391).

The first Gentrans round was carried out in 2005–2009 and the second round in 2011–2015. Survey answers are linked to register data on socio-economic variables. Individual in-depth interviews have been carried out with selected survey respondents. This longitudinal study is financed by the Academy of Finland.

Gentrans mainly studies the interaction and exchange between relatives but also includes data on attitudes and obligations to helping, and exchange between non-kin such as friends, neighbours and colleagues.

Gentrans surveys are planned to be repeated every fifth year in order to track changes in attitudes and practices as the baby boomer generation ages. The first survey was carried out in 2007 and the second in 2012.

The Gentrans project is partly based on the Survey of Health, Ageing and Retirement in Europe (SHARE). SHARE has gathered longitudinal information on older adults’ (people aged 50 or older) social relationships in over 20 countries since 2004. Finland has not participated in SHARE, but the Gentrans questionnaires are partly comparable with the SHARE data.
