A demographic trait varies across the world and in various literatures, no study has demonstrated much statistical association between the identified variables. Studies on self-esteem then encounter methodological problems and show that self-esteem evolves throughout childhood. Problems arise after having difficulty assessing when these changes affecting self-esteem in children and adolescents have been cross-sectional rather than longitudinal (Crago et al, 2009). In one of the few longitudinal studies conducted, Brown et al. found that self-esteem begins to decline at age 11 among white girls, but remains relatively stable among black girls between ages 9 and 14, and declines during middle age. adolescence from 13 to 16 years old (Crago et al., 2009). The study also concluded that self-esteem changes over time and the factors that affect self-esteem also change or not, from elementary to middle level.
