The data used in this research is given in phdoutcomes.csv.  For privacy reasons all 
potentially identifying information has been removed, leaving only those fields used in 
the calculations involved in the research.

A description of these columns is given below:

Column 1 (Gender)  : Gender of the individual (M or F; blank if unknown).
Column 2 (PhDYear) : Year of PhD receipt of the individual.
Column 3 (JobYear) : Year of starting first long-term job, or the current year 
                     (or limiting year) if a postdoc/adjunct.  NA if unknown.
                     On rare occasions this is actually before the PhD year. In most cases
                     this is because the PhD was technically awarded the calendar year 
                     after the student had truly finished, although in a few very rare 
                     cases a student had actually started employment while still pursuing
                     the PhD and remained at that job afterwards.  (I counted these as a 
                     hiring time of 0 years in the analysis.)
Column 4 (Left)    : Outcome.  One of:
     left        - left the field to pursue other employment 
     hired       - was hired into long-term job
     postdoc     - postdoctoral or similar role
     adjunct     - teaching or higher-level role that is explicitly short-term
Column 5 (InstClass) : Classification of employer.  One of:
   Astronomy:
     U-R1        - Carnegie-class R1 university (high research)
     U-R2        - Carnegie-class R2 university (moderate research)
     U-M         - Carnegie-class R3 or M univeristy (least research or Master's only)
     U-for       - University outside the US
     col         - Liberal arts, teaching, or community college
     obs         - Observatory (including NASA, STScI, IPAC, etc.)
     other-US    - Any other astrophysics institution in the US
     other-for   - Any non-university institute outside the US
   Non-astronomy:
     non-ast.ac. - University or other research facility but not working in astrophysics
     education   - Education other than higher-education (usually secondary education)
     government  - Government-related jobs (including federal/state agencies and military)
     industry    - Private industry, including most government contractors
     unknown     - Job could not be determined (but person had left)
Column 6 (JobType) : Classification of (long-term) job.  One of:
     prof        - Professor (not always tenure-track) or equivalent overseas role
     prof-R1     - Same as above, but always tenure-track and always at a R1 institution
     staff       - Scientific or operations staff position (a catch-all category)
     non-astro   - All non-astronomy jobs
Column 7 (Omit) : Whether the individual was omitted (TRUE) or used (FALSE) in analysis
           (Note that if Omit=TRUE most of the columns will have blank/incomplete entries)

The R markdown code used in this analysis is also included (it has been modified slightly 
to make use of this anonymized data set instead of the original .csv, but all calculations
are the same), along with a compiled notebook showing the inputs and outputs.
