The purpose of this paper is to visualize how vital the concept of social sustainability is to secure a sustainable society. To answer this, two surveys have been made. One study examines and compares how selected concepts are highlighted in the curricula Lgy 70, Lpf94 and GY11, in order to answer how the concept of social sustainability changed over time. The second survey analyzes the positive effects that may arise with increased social sustainability in the school. In order to answer this question, an interview has been made with a teacher who has been working for all three curricula. The choice of subject is based on the latest Friends-report, which states that every fourth child in school is exposed to abusive treatment and every tenth child is subjected to bullying. The essay is based on a hermeneutic theory whose purpose is to interpret collected material to bring in a deeper understanding. In order to create a deeper understanding, the essay has used a qualitative method that stands out to give an overall picture. The essay also contains a comparative method for analyzing similarities and differences between the different curricula Lgy70, Lpf94 and GY11. The results of the essay show that the concept of social sustainability has undergone a major change from the 1970s to today. The results also show that if social sustainability is given more space in education, hopefully we can see a reduction in discrimination in school. This would in turn result and contribute to a stronger society.
