I4NG Harmonised Data: Make it Strong!

The Infra4NextGen project is funded by the European Commission to support evidence-based policymaking aligned with the NextGenerationEU plan. As part of the project, harmonised datasets from major European cross-national survey programmes are being produced to increase sample size and coverage and to provide comparable indicators across five NextGenerationEU themes.

The I4NG Harmonised Data: Make it Strong! integrates data on social cohesion, democratic values, and institutional trust from five major European cross-national survey programmes: the European Values Study (EVS), the European Social Survey (ESS), the International Social Survey Programme (ISSP), the Eurobarometer (EB), and the European Quality of Life Survey (EQLS) along with new data collected through the CRONOS-3 panel (forthcoming in the second version of harmonised data). The dataset includes topic-specific sets of measures of perceptions, attitudes, expectations, and policy preferences concerning democratic resilience and social cohesion, covering concepts such as Democratic Participation and Engagement, Education and Learning, Employment and Work Conditions, Migration and Social Cohesion, Political Values and Democratic Perceptions, Social Trust and Preferences, and Trust in Institutions. The dataset includes 12 harmonised target variables.

The harmonisation process merged the items across surveys and standardised coding, scale direction, and missing-value structures across all source variables. A harmonised survey mode and three weight variables are provided. All source data derive from publicly available surveys archived at GESIS, SIKT, and the UK Data Service.
