Females | Women | Girls
A female organism is defined as the physiological sex that carries eggs. Unlike males, females are found in every species as they are vital to the process of reproduction, whether sexual or asexual. In humans, we refer to females as women if they are adults and girls if they are children or teenagers. Biologically, women have certain characteristics that distinguish them from men as a result of sexual dimorphism. Generally, these differences are most notable in height, weight, and body structure, though this is not always the case. A major difference between men and women is a woman’s ability to become pregnant and nurture a baby.
Typically out of 1,000 people there are 496 (49.6%) women and 504 men (50.4%). For every 100 girls there are about 107 boys born. The total world population is about 7.62 billion and the total number of women in the world is about 3.778 billion.
There is not universal age when a girl is considered a woman as it depends on the individual. A girl may be considered a woman by her maturity level or after becoming completely independent. Some cultures consider that a girl becomes a woman after her first menstrual cycle.
Women got the right to vote in the US after the 19th amendment gave the women the right to vote. The 19th amendment was passed by Congress on June 4, 1919 and it was ratified on August 18, 1920. Achieving this milestone took decades of protests by women suffrage supporters who lobbied, marched, lectured, wrote, and committed civil disobedience to achieve this goal.
