The National Educational Panel Study (NEPS) presented itself – supported by the German Research Foundation  – to an international audience of scientists under the title „Longitudinal Data Resources for the Social Sciences“. SOEP, SHARE, PAIRFAM and NEPS are the four mayor large-scale longitudinal studies in German social sciences that provide a unique data infrastructure on topics like inequality, aging, living arrangements, and education. All four projects make their comprehensive data available to the scientific community thereby providing a well-founded basis for innovative, cross-national, and interdisciplinary research. The representatives of the four longitudinal studies seized the opportunity and established contacts  with  scientists from of all over the world  during a reception and at the convention booth.
