Population profile of the United Arab Emirates

This population profile greatly intrigued me so I decided to share it.  It is comparing population differences in regards to sex and age in the United Arab Emirates.  It is interesting to note that in the early and late stages of life, the male population is nearly equal the female population.  However, in the middle stages of life, the male population more than doubles the female population.  Is this due to the ethical standards of the UAE? Very interesting to note.
