What socio-economic background does Sophie belong to? What are the indicators of her family's financial status?

Explanation

Sophie belongs to a lower middle class socio-economic background. She lives in a small house with her parents and two brothers, Derek and Geoff. When she returns home after school, she feels choked with the steam of the stove and is disgusted with the dirty dishes piled in a corner. Her mother's back has become stooped and bent by handling all the household chores and responsibilities on her own. Her father is a hard labourer and her elder brother, Geoff, works as an apprentice mechanic in a garage situated far away from his house. Her family wants Sophie to join work immediately after her school. These are some of the indicators of Sophie's family's financial status.
