potential data sources for the Digital Nomad Community Matchmaker (DNCM) app. I've identified a wide array of online textual data, including various digital nomad and expat forums (like Nomadlist, Reddit, Facebook groups, InterNations, Meetup.com, Slack groups), specialized blogs by long-term residents, local community websites (city boards, cultural institutions, university event calendars, non-profit pages), social media (Instagram hashtags, Twitter discussions), online news, and academic studies. For structured data, I've looked into official reports from organizations like the UN, WIPO, and World Happiness Report, as well as economic and infrastructure data from the World Bank, ITU, and Numbeo, and geographic data like population density and urban/rural definitions.
