More boys are born than girls. On average, 105 boys are born for every 100 girls.
This difference in birth rates might seem small, but it is statistically significant. The spontaneous assumption is that the probability of a pregnant woman giving birth to a girl is the same as the probability of giving birth to a boy. However, this is not the case, as referenced in the data.
Boys vs. Girls: Birth Ratio
To illustrate the difference, consider the following table:
| Gender | Average Birth Ratio |
|---|---|
| Boys | 105 |
| Girls | 100 |
This slight overage in male births is observed globally. There may be various biological and evolutionary reasons for this phenomenon, although these are not directly addressed in the reference information provided.
