Short description:

A feasibility study for a data production and dissemination exercise: Developing and enhancing a comparative database for longitudinal household studies by harmonizing and integrating micro datasets from a large variety of independent national panels and from the European Community Household Panel.


TÁRKI was responsible for harmonising and integrating Hungarian Household Panel to CHER comparative longitudinal database. We also prepared analyses that was published in CHER working paper series.

Description of Project:

The main work of the consortium was to create the comparative micro database of CHER, which contains comparable variables transformed according to a common plan and was built by using standardized international classifications where available. Information in these files are available (a) for households and individuals on the micro level, (b) for single years and (c) as longitudinal information, all of them linked to macro and institutional data. The comparative database contains harmonized and consistent variables and identical data structures for each country included: 14 EU countries, Poland, Hungary, Canada and USA. The data are stored as system files for the statistical packages SPSS, SAS and Stata. They contain identical variable names, labels, values and data structures. Each country file is adequately anonymized and can therefore be rated as a scientific use file. On the basis of dissemination rules agreed upon between the Consortium and the data owners, the database is available on a CD-ROM and it is distributed to the scientific community, under appropriate rules for confidentiality and data protection.

Abstract: While child poverty is a well-examined topic both in country level analyses and cross-country comparisons as well, panel analyses of this notion, especially in European context is far less common. The present paper intend to provide a both longitudinal and cross-country analysis of children’s poverty, focusing on people living in families with children. A comparison of Western and Eastern European countries is also an aim of the paper. For analyses paper uses data from the CHER database, a longitudinal harmonised dataset for 16 European countries. Examinations cover the middle period of 1990s, namely four years that between 1994 and 1997, inclusive. A group of seven countries, that includes Hungary, East Germany, Germany (included East Germany), France, United Kingdom, Italy and Denmark, was selected, as representative of different welfare regimes.
