Citizen-government interaction has been innovatively improved through the use of e-Government services. Such e-services provide governmental agencies with the opportunity to enhance their reputation and increase citizens' engagement with them. However, accomplishing this transformation will not be achieved without removing any impediments that affect citizens' trust in the provided e-services. This paper aims to understand the way social individual differences (age, gender, education level, and Internet experience) affect citizens' trust in e-Government services in developing countries. A survey, looking at people's perception of trust in e-Government, of citizens drawn from different geographical areas in Saudi Arabia, was conducted. The findings of this research indicate that out of the four factors investigated, only education level has a significant impact on citizen's trust in e-government services. Therefore, it appears that as educational level increases, so does citizen's trust in e-government and so they are more likely to engage with these e-government services.
