However, the problem of the country-specific differences found in such studies has not been addressed in depth and considering the wide range of social media sources. This paper presents a cross-country comparison of altmetric coverage between Spain and a selection of 16 countries (EU-15 and the United States) in 22 research fields. All Spanish publications indexed in <em>Web of Science</em> that were published between 2016 and 2020, as well as all mentions of their altmetrics collected on <em>Altmetric.com</em>, were retrieved. The results show that, of the 434,827 Spanish publications considered, 55% are found on <em>Altmetric.com</em>. General altmetric coverage in Spain is similar to that in the rest of Europe and the United States, but it is in areas such as Arts &amp; Humanities and Social Sciences where the lowest levels of coverage are found, although in the case of the latter the publications receive a higher number of mentions. Spanish publications reach a total of 3,569,553 mentions from different social media platforms, but <em>Twitter</em> is the main source of these mentions, accounting for 89%. Differences between research fields are also found, such as Environment &amp; Ecology receiving a higher number of policy mentions.</p> ER -
