In this study, we examine the relationships between self-reported media literacy skills, actual knowledge of news media literacy, and three sociodemographic factors: age, gender, and level of education. Data were collected through an online survey among a national sample of adults (n = 871) in Latvia. A significant positive correlation was found between all self-reported media literacy subscales and the knowledge subscales of news media literacy. Age was moderately negatively related to self-reported media literacy skills and weakly negatively related to news media literacy knowledge. The level of education was weakly positively correlated with both media literacy skills and news media knowledge. Gender does not significantly predict either news media literacy or media literacy. Relatively low levels of knowledge were found concerning the three dimensions explored: media industries, media content production, and media effects.
