The Matriarchs: Caitlyn and Kris Jenner’s Generational Gap

The foundation of the entire Kardashian-Jenner empire rests on the two powerful matriarchs, Caitlyn Jenner and Kris Jenner. Caitlyn, born in October 1949, is the eldest core member of the family, hitting the significant age of 76 in late 2025. Her life, from Olympic fame to her transition and political activism, has been a decades-long public journey.

Just six years her junior is the ultimate "Momager," Kris Jenner, who celebrated her 70th birthday in November 2025. This milestone birthday places her at the beginning of a new decade, continuing to manage the careers of her six children and overseeing the family's media presence. Their combined influence and generational difference of six years set the stage for the entire family's narrative, with Kris being the central figure in the reality TV dynasty.

The age gap between Kris and her eldest daughter, Kourtney, is 24 years, highlighting the generational span of the family. The four Kardashian siblings—Kourtney, Kim, Khloé, and Rob—were all born within an eight-year period, creating a tight-knit and highly competitive core group.

The Core Four: Kardashian Siblings' Birth Order and Business Empires

The original four siblings from Kris’s first marriage to the late Robert Kardashian Sr. are the heart of the "Kardashian" brand. Kourtney, born in 1979, is the oldest sibling at 46. She has successfully carved out a niche in the wellness space with her Poosh brand, focusing on a more holistic lifestyle compared to her sisters' ventures.

Kim Kardashian, who turned 45 in October 2025, is the second-oldest. Her rise to global fame is unparalleled. In 2025, her focus remains heavily on the expansion of SKIMS, a shapewear and clothing line valued in the billions, and her continued pursuit of a law degree.

Khloé Kardashian, 41, is the third sister. Known for her candid personality and fitness journey, she is the driving force behind Good American, a successful brand focused on body-inclusive denim and apparel. Her life with her children, True and Tatum, is a frequent storyline on their current show.

Rob Kardashian, the only son, is the youngest of the original four at 38. While he maintains a lower public profile than his sisters, he is still an integral part of the family, focusing on his sock line, Arthur George, and raising his daughter, Dream Kardashian. The compact age difference among the "Kardashian" siblings—Kourtney (46), Kim (45), Khloé (41), and Rob (38)—is a key factor in their shared history and close, yet often dramatic, relationships.

The Jenner Generation: The Youngest Sisters and Their Global Impact

The youngest duo, Kendall and Kylie Jenner, represent the second generation of siblings, born to Kris and Caitlyn Jenner. Their birth order is separated by just under two years, but their careers have taken distinctly different paths.

Kendall Jenner, who turned 30 in November 2025, is the older of the two Jenner sisters. She has established herself as a high-fashion supermodel, consistently ranking among the highest-paid models globally. Her business focus is more aligned with the luxury market, including her 818 Tequila brand. Her 30th birthday marked a significant entry into a new decade, celebrated just a few weeks after her mother's 70th.

Kylie Jenner, at 28, remains the youngest sibling in the entire family. Born in August 1997, she was the first to achieve "billionaire" status (though later disputed) through her beauty empire, Kylie Cosmetics. Her ventures, which also include Kylie Skin and Kylie Baby, demonstrate a shrewd business acumen that rivals her older sisters. She is a powerful entity in the beauty world, constantly setting trends for the Gen Z demographic.

The age gap between the oldest sibling, Kourtney (46), and the youngest, Kylie (28), is a substantial 18 years. This generational difference explains the distinct cultural and business approaches between the older Kardashians and the younger Jenners. The older siblings grew up with the rise of social media, while Kendall and Kylie are truly digital natives, leveraging platforms like Instagram and TikTok from the start to build their personal brands and business entities.

Topical Authority: The Expanding Kardashian-Jenner Grandchildren

To fully appreciate the family's age order in 2025, one must also acknowledge the next generation: the grandchildren. As of late 2025, Kris Jenner is a grandmother to 13 children, all of whom add another layer to the family's generational timeline. The age order of the grandchildren is a topic of its own, but it’s important to note the youngest additions: Kylie’s son Aire Webster, Khloé’s son Tatum Thompson, and Kourtney’s fourth child, Rocky.

The Kardashian-Jenner family's age order is more than a simple list of numbers; it's a blueprint for one of the most successful family empires in modern history. The collective strength of the family—from Caitlyn’s pioneering spirit at 76 to Kylie’s youthful business savvy at 28—is what keeps the public endlessly fascinated and the family's influence on pop culture, fashion, and business stronger than ever in 2025.
