The objective of our work is to verify the impact of the improvement of health conditions and literacy on economic growth in Morocco during the period between 1980 and 2018. We based ourselves on the work of (Mankiw et al., 1992), in which they studied the impact of human capital on economic growth by integrating it as a component in the Solow model. The data we have used mainly comes from the High Commission for Planning and the World Bank. The observation that we have made is that the composite health and literacy index that we have developed has no significant impact on the growth of GDP per capita in Morocco during the period studied, which means that the literate and healthy work force does not have the expected effect on economic growth in Morocco. Thus, to be able to take advantage of its qualified and educated workforce, we suggest that the Moroccan authorities should encourage investments in sectors of activity that require this kind of workforce, because the study of the current market situation of employment in Morocco has shown that the agricultural sector and the informal sector have a significant share in the national GDP, but recruit an illiterate or low-skilled workforce.
