Gender in our children's books – a dataviz by Nina Koch

Kids are absorbing the world around them. They are creating their knowledge and believes from scratch. We, as parents, are trying to set an example of an equal relationship. Plus we read a lot to our children. Thus I was wondering: What are we telling our kids about the roles of men and women in the books we are reading to them?

I wanted to focus on
a) what do our kids see? = who is appearing and what are they doing?
b) how to change things? = where did we get the books from? Which aspects should we keep an eye on?
