I have a large polygon dataset (26,000) records with numerous attributes columns. I wish to calculate the percentile rank of each attribute. Say I have population_density in an attribute, is there a simple formula to assign a rank in another attribute field on the percentile score of the value in the first attribute column (pop density)?

You can do this using arcpy in conjunction with numpy:
Just modify the code to adapt to your data and change the number of ranks as needed.
