Is there any evidence to support a preference for second-career pastors coming disproportionately from IT? Anecdotally, I know a lot of bi-vocational and second-career pastors who came from IT. At seminary, I saw a lot of them, and 2 of the 4 pastors at my current church have this background.  

I remember reading William Willimon who essentially said there were really only three kinds of professionals who had to read texts closely: lawyers, IT folk, and pastors. That has stuck with me, and led me to see a natural flow from IT to the pastorate. 

My question is - do I just notice this because of my own IT background, or is there any sort of statistical evidence that would bear this out? Where could I find a good data source to see first careers of second-career pastorates in the United States?
I emailed Cynthia Woolever of The Parish Paper and got this response:


  The statistics come from the U.S. Congregational Life Survey (Wave 2)
  conducted in fall 2008 and spring 2009. Almost 700 pastors (693 to be
  exact) completed an extensive survey about their background,
  education, and current experiences. These pastors had to be currently
  ministering in a congregation as the solo or senior pastor to be
  eligible. Therefore, ministers in specialized positions (like hospital
  chaplain) were not in the survey. Much of the details are on the U.S.
  Congregations website. Further details are reported in our book,
  "Leadership That Fits Your Church: What Kind of Pastor for What Kind
  of Congregation" published by Chalice Press (2012). 
  
  I remember from reading the "raw data" (actual returned surveys) that
  some pastors had been in IT work before working in a local
  congregation. However, we did not use this as a specific category when
  we coded the responses. Here are some of the relevant categories:
  Lawyers, judges, or legislators (3%) Teachers and professors (12%)
  All other professionals (28%) Managers and administrators (24%)
  
  Clergy who had previously been in the IT field would have been coded
  in the "All other professionals" category. Those in this category were
  also grouped by denomination or faith group. For Catholic priests--39%
  of those had a full-time occupation before entering ministry were
  coded as "all other professionals"; For mainline Protestant
  pastors--31% were coded as "all other professionals"; and for
  conservative Protestant pastors--20% were coded as "all other
  professionals."
  
  The entire dataset is available on the Association of Religious Data
  Archive.
