"Nothing vague here...."

The very fact they are using lifetime stats is a purposeful attempt to shift the statistic away from the x/100K or x/1000 rate metrics all social sciences and police forces have been using for half a century, now.

Look at the CDC study in the US, of the infamous "1 in 5 women will be sexually assaulted while at university" stat. They included unwanted kissing, touching over the clothes, sex while drunk, and included a positive consent requirement not found in the legal definition.  Use those CDC numbers and my Alma Mater, with 17 385 female students, would be seeing 3477 every four years, or 870 a year . That is a farcical stat. The school would shut down and no one would send their daughters.

Canada surveys the public directly, using the GSS, and we use the legal definition when we do. The rate? 22/1000/5rs, or 4.4/1000 annually.  With the GSS stat, my Alma Mater should see about 78 a year. What actually gets reported? Single digits or low double digits.
