This document summarizes interviews conducted with 20 data journalism leaders, experts, and trainers from 8 countries in 2016 about mobile data journalism practices. Key findings include: - Many were unfamiliar with the term "mobile data journalism" or questioned its usefulness - Small screens limit the amount of data that can be displayed and interactive features that can be used - Content must be adapted to various mobile devices and settings - Some saw opportunities for personalization, geolocation, crowdsourcing, and playfulness on mobile - However, mobile has not significantly changed data journalism practices yet beyond adapting the end product for mobile platforms. Follow up interviews and analysis were planned to explore changes and examples.
