you can generate (sub)field-level statistics with:
$ marcstats.pl data.mrc
# or
$ catmandu convert MARC to Breaker --handler marc < data.mrc > data.mrc.breaker
$ catmandu breaker data.mrc.breaker
# or
$ catmandu breaker --as XLSX data.mrc.breaker > data.xlsx
I'm not aware of any generic solution for generating statistics for specific (sub)field values. I would create a fix for these (sub)fields and then use something like
$ cut | sort | uniq -c
for calculating the numbers.
Best
Johann
