Determining a percentage of the world's population that is considered "good looking" is subjective and challenging. Beauty standards vary widely across cultures and are influenced by individual preferences. What is considered attractive to one person or culture might differ from another.
Beauty is a multifaceted concept that encompasses physical appearance, personality, and other subjective factors. Furthermore, judgments about attractiveness are influenced by social and media influences, making it difficult to quantify beauty in terms of a simple percentage.
It's important to remember that beauty is not an objective measure of worth or value. Everyone has unique qualities and characteristics that make them attractive in their own way. Focusing on inner qualities like kindness, empathy, intelligence, and compassion can lead to a more inclusive and meaningful perspective on beauty.
