sex ratio
Males per females
Sex ratio is the proportion of males to females in a population, typically expressed as the number of males per 100 females.
At birth, most human populations show a slight excess of males, roughly 105 to 100, though this ratio shifts over the lifespan as males tend to die younger.
Demographers and biologists track sex ratios to understand population dynamics, detect potential problems like sex-selective practices, or study species behavior.
The country's skewed sex ratio reflects decades of son preference.
