According to an article posted on the Church's official website, a new stake has been created in Mexico. There were 210 stakes in Mexico at the end of 2007 and one stake has been created so far this year in Pachuca. The article states that there are currently 212 stakes, so one stake was recently created. The article is about the Mexico City Mexico Temple being rededicated next month. Here is the link for the article.
I will provide the name of the new stake once in becomes available.
