The purpose of the study is to monitor, on a regular basis, the quality of life in European cities. The results of the study show how satisfied citizens are with various aspects of urban life, such as employment opportunities, presence of foreigners, public transport and pollution in their cities. When measuring progress or digress in satisfaction with aspects of urban life, essential is a reliable starting point. For example, to know if citizens’ satisfaction with job opportunities in their city increased or declined over a certain period, a a zero- measurement of citizens’ satisfaction and a new measurement later in time are both needed. Crucial for this process are the similarity of the operationalisation of the indicators for both measurements and, as in any data collection effort, a high degree of certainty about the correctness of these measurements. A reliable and consistent survey methodology that allows accuracy and comparability is therefore essential. Central aspects of this methodology, which are discussed in detail in this Evaluation Report, are the sample design and weighting procedure, the questionnaire design, the translations and the fieldwork organisation. This report presents the evaluation of the methodology, execution and output of the 2023 wave of the Perception Survey, including questionnaire design, sample and recruitment design, data collection, data processing, weighting and quality control. This information is shared to support users of the Perception Survey data in their assessment of the survey quality and the intepretation of the results. This evaluation report is accompanied by a technical report, which forms the second part of the final report. The technical report lists, per city, the most important sample performance data (amount of sample used, eligibility rate, refusals, response rate, average interview length, etc.)
