How often is national data updated?
We try our best to check and update the national data annually. However, not all the data will be updated every single year. This is because some data of the data is not available to the public domain every single year. Some countries don’t publish their data to the public every single year and some countries delay the data for a certain time before it goes public. So, if you are viewing the website in 2021, you might see some data are in between 2015 to 2021 for example or even older.
