"The Harmonized Histroies data file was created by the Non-Marital Childbearing Network (www.nonmarital.org) (see Perelli-Harris, B.; Kreyenfeld, M.; Kubisch, K.: Harmonized histories: manual for the preparation of comparative fertility and union histories (2011) Rostock, MPIDR Working Paper WP-2010-011).
It harmonizes childbearing and marital histories from 14 countries in the Generations and Gender Programme (GGP) with data from Spain (Spanish Fertility Survey), United Kingdom (British Household Panel Study) and United States (National Survey for Family Growth). Thank you to everyone who helped collect, clean, and harmonize the Harmonized Histories data, especially Karolin Kubisch at MPIDR."

Overview

The Harmonized Histroies data file was created by the Non-Marital Childbearing Network (see Perelli-Harris, B.; Kreyenfeld, M.; Kubisch, K.: Harmonized histories: manual for the preparation of comparative fertility and union histories (2011) Rostock, MPIDR Working Paper WP-2010-011). It harmonizes childbearing and marital histories from 13 GGP countries with data from Spain, United Kingdom and United States. The data file builds on the public release files of the GGS by further harmonizing and standardizing the histories within the GGP and ensuring the data is ready for use in event history analysis. The GGP is indebted to the Non-Marital Childbearing Network for its work on the standardisation of partnership and fertility histories and making this data file publicly available to the GGP Research Community. Access to the harmonised histories file is provided through the GGP User Space. Users with existing access to the GGP are granted access automatically and will need to log out and then log in again to access the data.

Acknowledgements

Initiators

We are very grateful to the members of the Nonmarital Childbearing Network www.nonmarital.org from various research institutions who in 2009 initiated the idea of a comparative database of union and fertility histories. Brienna Perelli-Harris, Michaela Kreyenfeld, Karolin Kubisch, Wendy Sigle-Rushton, Renske Keizer, Paola DiGiulio, and other members of the Nonmarital Childbearing Network created a manual to facilitate the harmonization (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).

Harmonized Histories team

We acknowledge the important contribution of the project head Brienna Perelli-Harris (Max Planck Institute for Demographic Research and later University of Southampton) and of the project leader at the Max Planck Institute for Demographic Research Michaela Kreyenfeld.

We acknowledge the important contribution of Karolin Kubisch at the Max Planck Institute who managed the standardization and cleaning process of the surveys. She also drew up detailed documentation, updated the surveys, and responded to users.

We acknowledge the important contribution of Sigrid Gellers-Barkmann at the Max Planck Institute who managed data distribution from Rostock and was responsible for data protection and contacts with users.

Institutional support

This project would not have been possible without the encouragement and financial support of the Max Planck Institute for Demographic Research (MPIDR) in Rostock and the support from the Datalab of the MPI and especially its  head Vladimir Shkolnikov, who supported the enormous amount of work of Karolin Kubisch on this project.  We are also grateful to the former director of MPIDR Joshua Goldstein for his support.

We also thank the IT department of the MPIDR for technical support especially in the development of secure data transfer methods.

Individual contributors

We thankfully acknowledge the contributions of the following researchers and institutions. In alphabetical listing by country/area, they include:

Many thanks to our users for helping to find errors in the database, including Aija Duntava, Gerda Neyer, Sunnee Billingsley and Gunnar Andersson from Stockholm University, and Paulina Galezewska and Julia Mikolai from the University of Southampton.

Data provider

GGS data were obtained from the GGP archive and were created by the organizations and individuals listed at www.ggp-i.org/about/organisation/consortium.

UK: The BHPS study is funded by the Economic and Social Research Council (ESRC). The data was originally collected by the ESRC Research Centre on Micro-Social Change at the University of Essex. Over time, additional funding for the British Household Panel Survey (BHPS) has been provided by the Health Education Authority (HEA), Office for National Statistics (ONS) and Eurostat. The HEA helped to carry out the survey of 11-15 year old members of the BHPS sample included from Wave 4 onwards. The Northern Ireland sample, included from Wave 11, is jointly funded by the Economic and Social Research Council (ESRC) and various Northern Ireland government departments. Chiara Daniela Pronzato cleaned the fertility and partnership histories and her data set (available from the UK data archive) was used in this analysis. (see: www.nonmarital.org/HarmHist-GB.htm)

Netherlands: Data about the Netherlands were derived from the The Family and Fertility Survey 2003 (Onderzoek Gezinsvorming). The FFS contains detailed information about relationships and family (formation). Data were collected by Statistics Netherlands. (see: www.nonmarital.org/HarmHist-Netherlands.htm)

For Spain, data comes from the Spanish Fertility Survey. (see: www.nonmarital.org/HarmHist-Spain.htm)

Please note: "The Survey of Fertility and Values was collected by the Centro de Investigaciones Sociológicas, but it is still undergoing processing. Therefore, the CIS holds no responsibility for any inaccuracies found in the data."

USA: The National Survey of Family Growth was conducted by the Division of Vital Statistics at the U.S. Centers for Disease Control. (see: www.nonmarital.org/HarmHist-US.htm)

Germany Pairfam: For Germany, we include data from the German Family Panel (pairfam) into the Harmonized Histories. We include data from the German Family Panel, because of potential data limitations of the German GGS (Kreyenfeld, Hornung, & Kubisch, 2012).Caution should be used when using the German Family Panel as it follows a cohort approach and includes only respondents of the birth cohorts 1971-73, 1981-83, 1991-93. Also note that the German Family Panel includes an oversample of East Germans, so that descriptive analysis need to be weighted.
