I think that null values in employment_occupation and employment_industry is due to the privacy reason.
I think that randomly giving NULL values to this columns makes volunteer data much more anonymous.

Hi Gaurav, Yes I had a similar confusion and hence imputed the NA in these two categories as “Unknown”. Worked well for me. Waiting for more opinions.
