👉 Sex math, or sex ratio analysis, is a statistical tool used to examine the balance between males and females in a given population. It calculates the ratio of males to females, typically expressed as a percentage, to assess whether a population is skewed towards one gender over the other. This metric is crucial in fields like demography, public health, and sociology, helping to understand population dynamics, resource allocation, and potential social impacts. For example, a sex ratio skewed heavily towards males might indicate higher infant mortality rates or challenges in finding partners for men, while a skewed towards females could suggest issues like female infanticide or limited opportunities. By analyzing these ratios, researchers and policymakers can make informed decisions to promote gender equality and address demographic imbalances.
