Summary

The Spanish Survey of Household Finances 2020 (EFF2020) provides detailed information on the income, assets, debt and spending of Spanish households as at end-2020. Given the lack of alternative statistical sources that provide detailed household-level information on these variables for the same households, the concurrence of this edition of the survey with the COVID-19 pandemic makes it unique, allowing for all these variables to be analysed together in an exceptional setting. As in previous editions, this paper provides a detailed description of the most relevant methodological aspects of the design and implementation of the 2020 edition, including: the sample design, the questionnaire, the data collection process, the validation of the data, the computation of weights and the imputation procedures. In addition, it also describes the most important methodological changes that had to be implemented as a result of the pandemic, mainly the interviewing mode, which was switched from CAPI to CATI.
