Based on 2010 population counts, there are slightly more men in the world than women. Estimates put the gender ratio for the whole world at 102 men for 100 women. In other words, for every 1000 people, 50.4% of them are male.
At birth the ratio is higher, with 107 boys for every 100 girls. Boys have a higher risk of death in childhood and adulthood, so the ratio levels out. At increased ages, the ratio favors women. The United Arab Emirates has the largest gender ratio of 228 males to 100 females. The country with the largest female ratio is Estonia, with 85 males for every 100 females.
