Open data is data anyone can use and share. It has an open licence, is openly accessible and is both human-readable and machine-readable.

You’re probably already using open data every day – for example:

  • geospatial information (getting from A to B)
  • weather data (deciding how to dress for the day)
  • Census data (making business decisions).

Open data drives innovation. It helps to build new business and encourages more strategic investment – creating new jobs, new industries and stronger economies. It can also lead to positive social and cultural outcomes, and can increase transparency and democratic participation.
