The Involvement of Lived Experience Experts On the Atlas, LEEs have: Simplified language to ensure inclusivity and ease of understanding for all users Contributed to designing a user-friendly platform for quick and intuitive navigation Been actively involved in pilot testing, influencing meaningful changes like enhanced website accessibility. Brought unique experiences and valuable lived experience to the project, significantly shaping its direction. Quote: As a black African, this project helped me communicate what the mental health landscape looks like where I come from - which is sometimes stereotyped and misunderstood. Lived experience advisors remain critical in understanding mental health in communities working towards decolonisation of the understanding of mental health and wellness. Quote: Lived experience has the potential to tailor mental health research priorities, and this project gives a perfect example of research co-production.

Text: Facts from around the world Most datasets in South America are concentrated in Brazil. Notably several have been following participants for decades with as many as 100 million participants. The longitudinal datasets with the oldest data are based in Denmark, with linkage data from 1870. Europe is home to the highest number of registries containing longitudinal data routinely collected, usually in a healthcare setting. Out of the world's low-and-middle-income countries, China has the highest number of longitudinal datasets featured on the atlas, with India and South Africa following next.

How can the Atlas help you? For governments: Can summaries information about the population-based datasets that have generated findings for policies. For students: Can reveal readily accessible datasets that can be downloaded and analysed for dissertation projects. For lived experience experts: Can provide ideas for research areas relevant to interests, expertise, projects of involvement or communities Logos: King's College London, MQ Mental Health, Wellcome Trust, Atlas of Longitudinal Datasets
Text: How can the Atlas help you? For researchers: Can externally validate machine learning codes or provide potential datasets for upcoming funding applications. For funders: Can highlight the gaps and opportunities in topics and data collection, which orient and guide future funding calls. For participants and the public: Can convey the richness of longitudinal datasets and researching a global context and can encourage participation.
