There are an estimated 4,800 jaguars in Mexico, found the study, carried out by a consortium of institutions and academics with remotely activated cameras triggered by sensors.
That was a 20-percent increase from the first edition of the study, carried out in 2010.
The jaguar, the largest feline in the Americas, can weigh up to 100 kilos (220 pounds), though the ones found in Mexico rarely weigh more than 60 kilos.
The yellow, black-spotted cats are found in 18 countries across the Americas, 90 percent of them in the Amazon rainforest.
In Mexico, however, a conservation program launched in 2005 and overseen by Mexico's national parks service has bolstered the jaguar's population growth, said the lead researcher on the study, Gerardo Ceballos of the Ecology Institute at the National Autonomous University of Mexico.
Researchers from 16 institutions and 25 academic groups carried out the study across 10 Mexican states, using a total of 396 cameras.
