Tilastotai

Tilastotai is an online platform and community focused on statistics and data literacy. It serves as a central portal for discovering, analyzing, and sharing statistical data and analyses. The project aims to lower barriers to data access, promote reproducible research, and facilitate collaboration among researchers, students, journalists, and policymakers.

Tilastotai was founded in 2015 by a coalition of statisticians and educators in the Nordic region, and it grew from regional data initiatives into an international open-data and open-analysis platform. It aggregates datasets from official statistics agencies, research projects, and user-contributed sources, and it emphasizes transparency and accessibility.

The platform provides a data catalog, interactive dashboards, visualization tools, and a notebook-based environment for reproducible analyses. It offers an API for programmatic access to datasets and metadata, enabling researchers and developers to integrate Tilastotai data into other tools. The project supports common open data licenses and promotes standard formats and interoperable metadata.

Tilastotai operates under an open-data license framework, typically Creative Commons or similar, with a focus on data provenance, metadata quality, and audit trails. Access is generally free, with optional paid tiers for enterprise features or restricted data when necessary.

Governance is community-driven, with a board and working groups overseeing policy, quality assurance, and community guidelines. Contributions, including datasets and analyses, undergo review to maintain reliability. The platform is used by universities, government agencies, journalists, and civil society to explore trends, run simulations, and communicate statistical findings. Potential limitations include data gaps, varying update frequencies, and concerns about privacy and misinterpretation. See also: Open data, Data visualization, Reproducible research.
