{fig-alt="Logo for the TidyTuesday project, represented by the word TidyTuesday over a messy splash of black paint"} **TidyTuesday** is a weekly social data project. All are welcome to participate! Please remember to share the code used to generate your results! **TidyTuesday** is organized by the [Data Science Learning Community](https://dslc.io). [Join our Slack](https://dslc.io/join) for free online help with R, Python, and other data-related topics, or to participate in a data-related book club! ## Goals Our over-arching goal for TidyTuesday is to provide real-world datasets so that people can learn to work with data. - [x] For 2024, our goal was to be used in at least 10 courses. Our survey indicates that we are used in at least 30 courses! - [x] For 2025, our goal was to crowdsource the curation of TidyTuesday datasets. We certainly didn't hit 100%, but we are grateful for the 51 pull requests, which included dataset submissions, improvements to welcome participants using Python and Julia, and other improvements to the project. We look forward to more community contributions in 2026! - [ ] For 2026, our goal is to provide tools for easier and better dataset curation, leading to curation of 95% of 2027 datasets by the end of 2026. *** ## How to Participate - Data is [posted to social media](dataset_announcements.md) every Monday morning. Follow the instructions in the new post for how to download the data in R, Python, or Julia, or download the data directly from GitHub for use in your favorite data exploration tool. - [Explore the data](https://r4ds.hadley.nz/), watching out for interesting relationships. We would like to emphasize that you should not draw conclusions about **causation** in the data. There are various moderating variables that affect all data, many of which might not have been captured in these datasets. As such, our suggestion is to use the data provided to practice your data tidying and plotting techniques, and to consider for yourself what nuances might underlie these relationships. - Create a visualization, a model, a [Quarto](https://quarto.org/) report, a [shiny app](https://shiny.posit.co/), or some other piece of data-science-related output, using R, Python, Julia, or another programming language. - Exploring the TidyTuesday data in Python? Posit has some extra resources for you! Have you tried making a [Quarto dashboard](https://quarto.org/docs/dashboards/)? Find videos and other resources in [Posit's PydyTuesday repo](https://github.com/posit-dev/python-tidytuesday-challenge). - Deploy or share your work however you want! If you'd like a super easy way to publish your work, give [Connect Cloud](https://connect.posit.cloud/) a try. - [Share your output and the code used to generate it](sharing.md) on social media with the #TidyTuesday hashtag. - R; TidyTuesday originated in the #RStats community on social media. Add that hashtag if you explore TidyTuesday data in R! - Python: Add the #PydyTuesday hashtag so that Posit has the chance to highlight your work, too! - Julia: Add the #TidierTuesday hashtag if you want the [Tidier Org](https://github.com/TidierOrg) to share your visuals! **You can also [curate a dataset for a future TidyTuesday](pr_instructions.md)!** *** ## DataSets ### [2018](data/2018/readme.md) | [2019](data/2019/readme.md) | [2020](data/2020/readme.md) | [2021](data/2021/readme.md) | [2022](data/2022/readme.md) | [2023](data/2023/readme.md) | [2024](data/2024/readme.md) | [2025](data/2025/readme.md) | [2026](data/2026/readme.md) | Week|Date |Data |Source |Article | |----:|:----------|:----------------------------------------------------------|:----------------------------------------------------------------------------------------------------------------|:----------------------------------------------------------------------------------------------------------| | 1|2026-01-06 |Bring your own data to start the year! |NA |NA | | 2|2026-01-13 |[The Languages of Africa](data/2026/2026-01-13/readme.md) |[Languages of Africa](https://en.wikipedia.org/wiki/Languages_of_Africa) |[Languages of Africa](https://en.wikipedia.org/wiki/Languages_of_Africa) | | 3|2026-01-20 |[Astronomy Picture of the Day (APOD) Archive](data/2026/2026-01-20/readme.md)|[NASA API](https://api.nasa.gov/) |[Astronomy Picture of the Day](https://apod.nasa.gov/apod/astropix.html) | | 4|2026-01-27 |[Brazilian Companies](data/2026/2026-01-27/readme.md) |[Open data CNPJ - December 2025](https://arquivos.receitafederal.gov.br/dados/cnpj/dados_abertos_cnpj/2025-12/) |[Wikipedia's List of largest Brazilian companies](https://en.wikipedia.org/wiki/List_of_largest_Brazilian_companies)| | 5|2026-02-03 |[Edible Plants Database](data/2026/2026-02-03/readme.md) |[Edible Plant Database](https://discovery.dundee.ac.uk/en/datasets/edible-plant-database/) |[GROW Observatory](https://www.dundee.ac.uk/projects/grow-observatory) | | 6|2026-02-10 |[The 2026 Winter Olympics!](data/2026/2026-02-10/readme.md)|[Milano-Cortina 2026 Winter Olympics Data](https://raw.githubusercontent.com/chendaniely/olympics-2026/refs/heads/main/data/final/olympics/olympics_events.csv)|[Olympics Schedule and Results](https://www.olympics.com/en/milano-cortina-2026/schedule) | | 7|2026-02-17 |[Agricultural Production Statistics in New Zealand](data/2026/2026-02-17/readme.md)|[Figure.NZ](https://figure.nz/table/TSQ8lkuKnyzfERF3) |[Gap between people and sheep rapidly closing](https://www.rnz.co.nz/news/country/560252/gap-between-people-and-sheep-rapidly-closing)| | 8|2026-02-24 |[Science Foundation Ireland Grants Commitments](data/2026/2026-02-24/readme.md)|[Science Foundation Ireland Historical Grants Commitments](https://data.gov.ie/dataset/science-foundation-ireland-grants-commitments)|[Science Foundation Ireland Historical Grants Commitments](https://data.gov.ie/dataset/science-foundation-ireland-grants-commitments)| | 9|2026-03-03 |[Golem Grad Tortoise Data](data/2026/2026-03-03/readme.md) |[Sex Ratio Bias Triggers Demographic Suicide in a Dense Tortoise Population](https://figshare.com/articles/journal_contribution/Sex_ratio_bias_triggers_demographic_suicide_in_a_dense_tortoise_population/30752687)|[Sex Ratio Bias Triggers Demographic Suicide in a Dense Tortoise Population](https://onlinelibrary.wiley.com/doi/10.1111/ele.70296)| | 10|2026-03-10 |[How likely is 'likely'?](data/2026/2026-03-10/readme.md) |[Kucharski AJ (2026) CAPphrase: Comparative and Absolute Probability phrase dataset.
