Know Your Data: Is It Good or Bad?

Before starting to create charts or maps, get to know your data.

  • Where did it come from?
  • Who compiled the data, and for what purpose?
  • What do the data labels really mean?
  • Ask yourself: Am I working with the most recent version, in the best available format?

Closely examine your data files to understand their meaning, sources of origin, and limitations. TODO: expand on this theme with examples of bad and misleading data
