यूरोपियन नज़रिए और मूल्यों पर दो दशकों का क्रॉस-नेशनल सर्वे डेटा। टॉपलाइन रिपोर्ट और प्रश्नावली अच्छे, ठोस सोर्स बनते हैं; डेटा मुफ्त है।

ESS has asked the same questions across dozens of countries every two years since 2002, using one consistent methodology, which makes it a rare source for tracking how attitudes have shifted over time rather than comparing one-off polls. Data and questionnaires are free to use. It only covers Europe, so it won't answer questions about attitudes elsewhere.
