Research over hundreds of years has consistently found that boys naturally outnumber girls at birth. The speculation is that this is nature's way of countering the relatively high mortality rates of males, and creating more of a gender balance in the population.
Worldwide, the male population is slightly higher than the female population, although this varies by country. As of 2021, the Special Administrative Region of Hong Kong, under the control of China, has the highest share of women worldwide with 54.2 percent. Curacao followed directly with 54 percent.

Approximately 84.48 males to 100 females live here as reported by 2021. It apparently has made first of 201 places in the world where more females live than men, according to the United Nations. Sometimes, data criteria varies slightly, especially when pulled from 2019 or earlier versus 2021.
The sex ratio at birth in every country is male-biased, ranging from around 101 to 112 boys per 100 girls. Four nations have a sex ratio above or equal to 1.10 at birth, as Azerbaijan has the highest male ratio with 112 male births per 100 female births, and all four belong to Asia.
