Everyone can apply or draw on the Code of Practice for Statistics. It can help anyone using data and producing statistics to work in a way that allows others to have confidence in their commitment to delivering the best possible outputs. 

The Code is based on three core principles, Trustworthiness, Quality and Value (TQV), with ten underpinning principles.  

Adhering to these Code Principles helps show you are trustworthy and that your data and statistics are of appropriate quality and valuable: 

Trustworthiness is when users can have confidence in the people and organisations that produce statistics and data

  • Principle 1: Show integrity 
  • Principle 2: Lead responsibly 
  • Principle 3: Be transparent 
  • Principle 4: Manage data responsibly 

Quality is when users can have confidence that the data and methods produce assured statistics

  • Principle 5: Prioritise quality  
  • Principle 6: Be rigorous  
  • Principle 7: Be open about quality  

Value is when users can have confidence that published statistics support society’s needs for information

  • Principle 8: Be relevant 
  • Principle 9: Be clear 
  • Principle 10: Be accessible  

Check out the Code Principles to see relevant dos and don’ts, aligned to each principle, when working data and statistics.
