CNEF • Research Areas covered: • Demographics, HH composition, • Region (basic), Health (basic) • Employment (basic), Education (basic), • Annual income (major focus) • Macro-Level information (e.g. CPI) • currently available data on 1980-2002 • PSID 1980 to 1997, 1999, and 2001 on over 33,000 individuals and 7,000 households - GSOEP 1984 to 2002 on over 20,000 individuals and 6,000 households. • BHPS 1991 to 2001 on over 21,000 individuals and 6,000 households • SLID* 1993 to 2001 on over 95,000 individuals and 32,000 households

9. Supported software formats: • SAS, SPSS, Stata, ASCII • CNEF information can easily be merged to original survey data • original identifiers supplied • Documentation & user support • Detailed codebook on methods and algorithms used to create each variable in each country, based on original survey variable names), anddescriptive statistics for each variable • “Reliability” codes for comparability of variables across countries • WWW-based user support and email-hotline http://www.human.cornell.edu/pam/gsoep/equivfil.cfm

10. ECHP European Community Household Panel

11. Overview of the ECHP • A harmonised cross-national longitudinal survey focusing on household income and living conditions • also includes items on health, education, housing, migration, demographics and employment characteristics. • runs from 1994 to 2001.

12. Wave One (1994) sample of some 60,500 households i.e. approximately 130,000 adults aged 16 years and over interviewed across 12 member states (Belgium, Denmark, Germany, Greece, Spain, France, Italy, Ireland, Luxembourg, The Netherlands, Portugal, the United-Kingdom). Wave Two 2 (1995) Austria, then Finland joined in wave 3 (1996) From Wave 4 (1997) Sweden provides cross-sectional data in the UDB format derived from its National Survey on Living conditions.

13. For most countries, surveys carried out using the harmonised ECHP questionnaire. For some countries the institutes in charge of the production of the ECHP converted national data surveys into ECHP format to replace the ECHP from 1997 onwards. Therefore some information might not have been collected in the national surveys so that they will appear as missing in the ECHP. In other cases, variables that were not collected in the national survey were imputed based on similar variables.

14. Nature of ECHP data by country and year (Harmonised original ECHP data and data derived from existing national sources)

15. Characteristics of the ECHP dataset • Multi dimensional character of the topics covered - microdata on a wide range of topics at the level of individual and household: income, social life, housing condition, health, education, employment, training, and so on. • cross-national comparability of the data - a harmonised and comparable dataset across countries achieved through implementation of common procedures at all stages from the design of a harmonised questionnaire, harmonised definitions and sampling requirements. • longitudinal nature of data -provides information on relationships and transitions over time at the micro level.

19. Rationale for EPUNet • ECHP not well utilised • ECHP complex and difficult to analyse • ECHP available but expensive and access administratively difficult • Potential users cannot “try before they buy” • Users are isolated from other users

20. EPUNet was set up by the European Panel Analysis Group • to encourage and support the maximum use of the ECHP data by independent analysts • to develop and maintain links between researchers analysing the ECHP was funded by the EC until end 2005
