The study was conducted on 288 children attending 4th and 5th years of primary school and coming from different socio-economic levels (i.e., low, middle, high). The general information form developed by the researchers was used in order to obtain information about the children and their families, the offer self-image inventory was used to identify the self-image and the Aggression Scale was used to identify the aggressiveness levels of children. Data from the research were analyzed with t-Test and ANOVA. The results showed that children’s socio-economic levels and parents’ education levels make a significant difference (p< 0.05, 0.01) while gender does not (p>0.05). It was also found that a meaningful relationship exists between self-image and aggressiveness levels (p< 0.01). Keywords: Investigation;self-image;aggressiveness;socio-economic level;children
