The proportion of New Zealand-based publications in the top 1% of world research, by field is based off the Field Citation Ratio (FCR). The FCR is a citation-based measure of scientific influence of one or more articles. It is calculated by dividing the number of citations a paper has received by the average number received by documents published in the same year and in the same Fields of Research (FoR) category.
The data in figure 39 is for publications produced in 2019 in the fields of research presented.

The data in figure 40 is for publications produced in 2010, 2019 (FCR) and 2020 (RCA) in the fields of research presented.
