This publication is a product of the Fertility and Family Survey (FFS) project, which was conducted between 1988 and 1999 by the Population Activities Unit (PAU) of the United Nations Economic Commission for Europe (UNECE), with financial support from the United Nations Population Fund (UNFPA). The objectives of the project were: 1) to conduct comparable Fertility and Family Surveys in UNECE member countries; 2) to create and archive FFS Standard Recode Files (SRFs); 3) to prepare FFS Standard Country Reports (SCRs); 4) to carry out a program of cross-country comparative research. The FFS IWG organized an end-of-project conference; the FFS Flagship Conference became an occasion for many researchers to present their findings of comparative analyses based on FFS data, in particular those studying partnership and fertility behavior. Volume one presents selected contributions to the FFS Flagship Conference solicited by the Organising Committee of the Conference. The second volume presents contributions received in response to a call for papers issued by the Organising Committee.
