You may be referring to either two "changes" in the Mexican population. The first, population growth, has been slowing because most Mexican women tend to have fewer and fewer children due to better contraceptive methods and greater education. Right now most Mexican women have between two and three children, while women of the last generation had between three up to twelve children.
The other change you may be referring to is the aging of the Mexican population. While last generation had a median age of 16 years and most population was young and unproductive, now it has a median age of 26.3 years and most Mexicans are young adults.
