Decision matrix with data for sustainable evaluation of cities collected for 2022

The presented data set was used to develop a sustainable city assessment model. The data set covers 21 countries and contains data collected for the year 2022 from the Eurostat database. Six decision criteria were chosen for the study. As a result decision matrix comprising 21 countries and 6 criteria was constructed. The dataset was collected from https://www.sustainabledevelopment.report/reports/sustainable-development-report-2022/ and saved as XLSX file called decision_matrix.xlsx provided in data.zip. A detailed description of the dataset is provided in the data.pdf file. The dataset is related to the research paper: Kizielewicz, B., & Bączkiewicz, A. (2025).
