What is Fortran used for?
Fortran is mostly used in domains that adopted computation early–science and engineering. These include numerical weather and ocean prediction, computational fluid dynamics, applied math, statistics, and finance. Fortran is the dominant language of High Performance Computing and is used to benchmark the fastest supercomputers in the world.

Fortran is also used a lot in quantitative economics. If you go to the data and replication archive of the Review of Economic Dynamics, you can find many codes in Fortran.

For a glimpse where Fortran is used, you can visit the compilation Fortran code on GitHub by @Beliavsky et al. organized by topics of interest. This is complemented by Fortran-related books (“Books with Fortran code, other than textbooks”).

This forum is dominated by people from North America and Europe. Do you know how many people use Fortran in China and India? They just don’t bother talking about Fortran online.

Boom. Mic drop. Singapore number three. A lot of hpc codes in many fields are in Fortran. When researchers get into those fields and develop they use Fortran.
