What is the difference with People-centered design (PCD), User-centered design (UCD) and Human-centered design (HCD)?

So I've noticed many people mention these 3 approaches:

  • People-centered design (PCD)
  • User-centered design (UCD)
  • Human-centered design (HCD)

I have been researching and I only found a good article in which they explain the difference between UCD and HCD. I will leave it here: https://www.digital-adoption.com/user-centered-design-vs-human-centered-design/

But then, what is the difference with People-centered design (PCD) and User-centered design (UCD)?

Thanks in advance,
