You always have to consider the sources when looking at these kind of biased numbers:

"The United Nations High Commissioner for Refugees — which refers refugees for resettlement in other countries — http://data.unhcr.org/syrianrefugees/regional.php. Its figures on the demographic makeup of refugees is based on available data on the 2.1 million who were registered by the UNHCR in Egypt, Iraq, Jordan and Lebanon. (Another 1.9 million Syrian refugees were registered by the Government of Turkey, and more than 24,000 were registered in North Africa.)
UNHCR’s data show that 50.5 percent of refugees are women. Females age 18 to 59 make up 23.9 percent of the refugees, while males in that age group make up 21.8 percent.
Even younger males — age 12 to 17 — represent 6.5 percent of refugees, while females that age are 6.1 percent. The majority of refugees — 51.1 percent — are under age 17, including 38.5 percent who are younger than 12 years old. These numbers were as of Sept. 6."
