I am running, so will just move and post Aaron's comments from this source:
This article published yesterday talks about the Legion's losses.
In detail it states that there was only on new vocation in 2013. I presume that they mean only one that wasn't from the apostolic schools.
It also cites some figures about the Anahuac Univeristy in Oaxaca: in 2009 it received 85 million pesos in donations. In 2013, it received 4.5 million pesos.
There are more figures about people leaving, but there is a little confusion or over lap of figures and dates... and we have the LC's official numbers here, comparing December 2012 with December 2013.
I should have looked at the Legion's statistics in more detail: the news articles uses the Legion's statistics but not clearly.
It is interesting to note the statistics presented by the Legion, scroll down the page to get the info on every year since 1992.
I like this particular phrase: If in previous documents there are different statistics, they are corrected here.
