At least 26,121 people were reported missing during the term of Mexican President Felipe Calderon, who launched the country's offensive against drug cartels, an official count shows .
Lia Limon, the Interior Department's subsecretary for human rights, says the list used data from local prosecutors across Mexico, and includes people reported missing for any reason during the previous administration. It doesn't include information collected after November 2012.
The list has been a subject of controversy in Mexico for weeks.
After Limon said last week that some 27,000 were missing, a member of Calderon's administration disputed the figure, saying the only registry on disappeared people contains 5,319 names.
Limon said the government would work to compare the official list with others assembled by government agencies and rights groups.
