I see. Thank you. That's a good clarification.
Is there anywhere a compendium of the history of reporting changes that have occurred? We've spoken about a number of reporting changes, including different versions of the uniform survey, which I thought was an interesting turn of phrase, but also various things, the crime severity index, of course, being recent, and now, of course, we know gang reporting in 1991. I wonder if that is collated anywhere and set down where one could sit and read a few pages of what the various changes in reporting have been since 1962.
