A new study from Warwick, Bielefeld University and University of Greifswald has analyzed data from 1,103 participants in the German Socio-Economic Panel (SOEP) and the UK Household Longitudinal Study Understanding Society (UKHLS) to find that life satisfaction is, on average, highest in the year after couples start living together. After that, it remains well above the level reported during single life for several years.
