To me, equality goes hand in hand with welcoming diversity.
There was a recent study by the CCBC (Cooperative Children’s Book Center) that made this shocking revelation:
Of the 3,600 books the Cooperative Children’s Book Center reviewed in 2012:*
3% were about Africans/African Americans; 1.8% were written by Africans/African Americans
1.5% were about Latinos; 1.6% were written by Latinos
Less than 1% were about American Indians; less than 1% were written by American Indians
2% were about Asian Pacifics/Asian Pacific Americans; 2.3% were written by Asian Pacifics/Asian Pacific Americans
