Erfi 2 is part of the international research infrastructure, Generations and Gender Programme (GGP). Launched at the initiative of the United Nations Economic Commission for Europe (UNECE), in the early 2000s, GGP has already carried out a first round of surveys in some 20 countries, which included France. In 2020, GGP launched a new round (in the form of 3 waves, where the waves are each 3 years apart). France is participating in this new round, which has already begun in several countries. To expand on the insights gained via the previous round, the new survey will focus on family dynamics as a whole: fertility, partnership, gender inequalities, intergenerational exchange, transition to adulthood (most notably in terms of leaving the parental home), and the transition to retirement.[1]
