Making terminology accessible to a non-expert audience is a challenging task for specialized writers. Indeed, they need to strike the balance between finding the right level of popularization for the intended addressee and keeping maximum precision. This task is even more daunting when specialized content is conveyed with the use of graphic elements. This paper presents some reflections drawn from a recent cooperation with the Swiss Federal Statistical Office (FSO) aiming at finding new ways for providing accessible institutional information within an action research paradigm. The analysis focuses on selected chapters of “Statistical Data on Switzerland”, a publication addressed to the broad audience that describes the country by means of statistics. It is compared with a new, provisional version drafted according to the standard of plain language, as well as with the “Statistical Yearbook”, that is its counterpart for a specialized audience. Moving from the French versions of the aforementioned publications, the focus is placed on the use of single- and multi-word terms in both textual and graphic parts. They were identified with the help of a term extractor and validated by a field expert at the FSO. The analysis shows that the FSO tries to adjust terminology according to its public, thus controlling the quantity and level of technicality of the terms used. Furthermore, adding definitions seems a useful way for ensuring precision in specialized texts and explaining unavoidable terminology in popularized texts. Finally, controlling the level of technicality and the presence of terms in graphic elements, as well as ensuring text-image coherence is key when enhancing the level of accessibility.
