Question Author
Thanks for your responses.
The reason I ask is because I have had a few discussions at work concerning different topics when people have stated that, "40% of the population go to church"; or "5% of the population have experienced recreational drugs".
I can even remember discussions about the percentage of the population that is in prison. Most recently there was mention of people with mental health issues. (We have great discussions at work!)
These last two concerns were pretty much dealing with adults and not children.
It's just recently dawned on me that some of the discussions were skewed in our assumption that the supposed percentages simply included adults only.
I think the media probably often make the same mistake.
Sorry, I can't think of any precise examplesof media bias just now !!
