Age divisions are generally broken as follows: 0–11 months, 12–23 months, 1–3 years, 4–6 years, 7–9 years, 10–12 years, 13–15 years, and 16–18 years.

Age divisions will often have names such as "Baby Miss", "Petite Miss", "Little Miss" and more. Often, age divisions for boys run through age 6 with very few going beyond that due to lack of participation and public perception.

While most beauty pageants cater strictly to girls, there are a growing number that include boys as well. Additionally, TLC, also an American network, has created shows such as Toddlers & Tiaras and King of the Crown, the former dedicated to the world of high glitz child pageantry and the latter to the world of pageant coaching. In 2001, American Network HBO aired its Emmy-winning Living Dolls: The Making of a Child Beauty Queen, which garnered much attention. Critics began to question the ethics of parents who would present their child in a way that was perhaps not suitable for their age. The murder of JonBenét Ramsey in late 1996 turned the public spotlight onto child beauty pageants. It has grown from the senior beauty pageants, previously originating from South America, in particular in Venezuela, to become an event held throughout the world for young boys and girls, with an emphasis on competitions being popularized by mainstream media in the United States, to much criticism. It is an increasingly lucrative business, bringing in about twenty billion dollars a year to the Americas with its popularity spreading worldwide. Since then, the industry has grown to include about 250,000 pageants. The modern child beauty pageant emerged in the early 1960s, held in Miami, Florida. Originally, it was for young people from 13 to 17 years old, but by 1964 there were over 35,000 participants, which prompted an age division. The Little Miss America pageant began in the 1960s at Palisades Amusement Park in New Jersey.

However, that idea had already circulated through " Most Beautiful Child" contests held in major cities across the country. Beauty pageants started in 1921 when the owner of an Atlantic City hotel struck upon the idea to help boost tourism.
