Do you notice the race of characters in your books?
Have you ever thought about the race of a character when reading a book?
Well last year 9,115 children's books were published in the UK, but only 391 of these - 4% - had a Black, Asian or Minority Ethnic (BAME) character.
Even when there was a character from an ethnic minority background, they were the main character in only 1% of these books.
But 32% of school children in England come from BAME backgrounds - so this means most of the books read aren't properly representing children in the UK.
These figures all come from a new study by a charity called the The Centre for Literacy in Primary Education (CLPE).
Many people think that things need to change and the characters need to reflect the kids in the UK.
