This publication aims to describe links between the health of Québec adults (16–65 years old) and skills related to literacy, numeracy and problem-solving in a technology-rich environment. Two health indicators are used: perception of health status and presence of a chronic health problem that limits or prevents activity. For each of them, an overall picture of the levels of competence in the three areas mentioned is first drawn. Then, again for each of these indicators, the variation in literacy and numeracy skill levels according to four sociodemographic variables, namely, gender, age, highest level of education attained and main activity, is studied. Using these variables as control variables, it is possible to see the extent to which the associations between health indicators and skills noted overall also apply to different population groups.
