The given table illustrates the population ratio of females per 100 males across six regions: Africa, Asia, Europe, North America, Central America, and Oceania, in 1995 and 2005.
Overall, Africa and Europe experienced an increase in the female-to-male ratio over the ten years, while the other regions saw a decline. Additionally, Asia recorded the highest ratio of females per 100 males in both years, whereas Europe exhibited the lowest.
In 1995, Asia had the highest female-to-male ratio at 105.3, followed closely by Oceania at 103.9. Meanwhile, North America and Central America had relatively balanced gender distributions, with ratios of 100.1 and 100, respectively. In contrast, Africa and Europe had fewer females than males, with respective ratios of 97.8 and 89.4.
By 2005, the ratio in Asia slightly decreased to 104.9, yet it remained the only region where females outnumbered males. North America, Central America, and Oceania also saw decreases, with ratios dropping to 96.9, 97.5, and 99.8, respectively. Conversely, Africa and Europe observed an upward trend, with their ratios rising to 99.2 and 92.8, respectively.
