What is Open Data Day?

Open Data Day is an annual celebration of open data all over the world. For the tenth time, groups from around the world will create local events on the day where they will use open data in their communities. It is an opportunity to show the benefits of open data and encourage the adoption of open data policies in government, business and civil society.

All outputs are open for everyone to use and re-use.

Ideas and data sources

Hey there open data enthusiast! You just saw that Open Data Day will be on Saturday 7th March 2020 and you're interested in hosting an event in your locality? Your only challenge now is finding the idea that will hit the right spot. Our friends from the open data community have some ideas and data sources worth checking out.

Data sources

Use data.world to upload or find data from many sources and organise all aspects of a project - including data, notebooks, analysis, and discussions - in a single workspace.

You can access the Humanitarian Data Exchange to find data related to humanitarian actions from different sources.

If you have data but don't know where to put it, you can use the CKAN DataHub. You can publish or register datasets, create and manage groups and communities.

Tracking Public Money flows

If you are planning on organising a track to follow the money, here are some interesting ideas and projects you can use to run your event:

DataOnTheStreets International Rally. A great opportunity to invite the public to use the data generated by governments, go out to the streets and see how data reflects in their real life. It is a public participation process in the budget implementation phase through open data and digital tools, such as maps and visualizations.

Better Budget Dataquest for sustainable development. The Dataquest is an opportunity to find new insights on certain topics and innovative ideas to improve budget allocations and execution.

These are two ways to engage people using budget and spending data.

Equal Development

LGBTQ rights - http://www.lgbtdata.com/ (note: This website does not state that the data is open, but links to datasets) War crimes - see for example how BVT datalab showed the story of the bombing in Barcelona during the civil war Immigration - see current work of the migrant files, openmigration + data from UNHCR on refugee situations Internet shutdowns - ways to combine information from AccessNow, Dyn Research, Akamai (SOTI) with other data sources Tax - could share some interesting things from Open Data for Tax Justice project about overlap between tax and human rights Tracking poverty in cities - not using open data, but interesting example of how alternative stories about poverty are told. The City of Indianapolis developed an open data portal to show information about the use of force, officers ­involved shootings and complaints against officers.)

Environment theme

Drought in Southern Africa In the news: Guardian, March 2016 Thomson Reuters, November 2016 Ongoing Data Work: Hack 4 Water (South Africa) http://www.hack4water.org.za/ https://www.dwa.gov.za/events/hack4water/default.aspx

Global Forest Watch provides several data sets on forest coverage, use, loss, and indigenous peoples.

Pollution - air, water

Sensor data from https://www.opensensors.io https://opendevelopmentmekong.net/ The map of “Spills in Brooklyn” visualizes records of the New York State Department of Conservation to show noxious chemical spills in different locations around New York’s neighbourhood Brooklyn. The app Allairgoo offers people with asthma or allergies individual information on air quality in multiple cities. It combines data on air quality ­ i.e. data of single pollutants, official air quality indexes, etc. ­with personal user data, for instance about chronic respiratory diseases. Airlapse shows the concentration of particles such as carbon monoxide per hour in different areas of the city of Bath (UK).


Open Oil releasing open financial models in the run-up to Christmas for around a dozen countries. Build on models/findings? http://openoil.net/contract-modeling/ Extract-A-Fact, a project by Publish What You Pay, is a toolset to find facts in open data on extractives industries, including payments made to the government.
