Pew Research Center

pewresearch.org

US के जनमत, डेमोग्राफिक्स और टेक इस्तेमाल पर सर्वे रिसर्च। रिपोर्ट पेज और डाउनलोड करने लायक टॉपलाइन PDFs, दोनों ही मजबूत सोर्स बनते हैं।

Good fit for a notebook tracking how Americans think about a policy, technology, or social issue over time, since Pew publishes methodology alongside every finding. It's nonpartisan and widely trusted across the political spectrum, which matters if your notebook needs a neutral read on opinion data. Coverage leans heavily US-focused, so don't expect it to anchor a global comparison.
