How do farm children evaluate their lives as a whole? Using the framework of Ed Diener, this paper explores farm children’s positive emotions, negative emotions, global life judgment and work satisfaction that will ultimately reflect their subjective well-being (SWB). It also discusses the nature of farm work engagement of these children and their positive and negative experiences on it. Using qualitative data, the paper found out that children are involved in different farming activities. In particular, the theme found on children’s positive experiences on farm includes the social reward of farming while prominent on their negative experiences are the physical injuries, negative bodily response and environmental hazards brought about by their work. Using quantitative data the paper found out that they have high level of SWB. The high level of SWB among children engaged in farming is characterized by high levels of positive emotion, global life judgment and work satisfaction, and low level of negative emotion. More so, significant differences on the level of SWB between in-school and out-of-school farm children were highlighted.
