The Nonmarital Childbearing Network

The Intersection Between Childbearing and Union Status

Harmonized Histories


One of the goals of the Nonmarital Childbearing Network was to create a comparative database of union and fertility histories. To facilitate the harmonization we created a manual (see Perelli-Harris, B.; Kreyenfeld, M.; Kubisch, K.: Harmonized histories: manual for the preparation of comparative fertility and union histories (2010) Rostock, MPIDR Working Paper WP-2010-011). Karolin Kubisch at the Max Planck Institute managed the standardization and cleaning process of the surveys.


The Harmonized Histories database is now located at the Generations and Gender Programme Website
