<B>Researchers per million inhabitants : </B>SDG Indicator 9.5.2: Number of professionals engaged in the conception or creation of new knowledge (who conduct research and improve or develop concepts, theories, models, techniques instrumentation, software or operational methods) during a given year expressed as a proportion of a population of one million.<br><br><B>Full-time equivalent (FTE) of R&D personnel: </B>The Full-time equivalent (FTE) of R&D personnel is defined as the ratio of working hours actually spent on R&D during a specific reference period (usually a calendar year) divided by the total number of hours conventionally worked in the same period by an individual or by a group. In other words, one full-time equivalent may be thought of as one person-year. Thus, a person who normally spends 30% of his/her time on R&D and the rest on other activities (such as teaching, university administration and student counselling) should be considered as 0.3 FTE. Similarly, if a full-time R&D worker is employed at an R&D unit for only six months, this results in an FTE of 0.5. Therefore, it is measured by combining two variables: actual involvement in R&D activities and formal engagement on the basis of normative/statutory working hours. FTE is considered to be a true measure of the volume of R&D and also the main R&D personnel statistic for international comparisons.

<B>Researchers per million inhabitants : </B>Number of researchers during a given year divided by the total population (using mid-year population as reference) and multiplied by 1,000,000.
