Basic Trope: A very large Nuclear Family.
- Straight: Jason has 15 siblings. He lives with all of them, and both of his parents, making for a total of 18 people in the house.
- Exaggerated:
- Jason has 300 siblings.
- Almost every significant character is shown to have a huge family, and some are implied to have more siblings who are unseen. Ida is an exception, but only because her father is dead.
- Downplayed:
- Jason has five siblings; his family is not huge, but it is fairly large by Western standards.
- Polygamy is the norm in Jason's homeland, and his father has several wives, so a number of the kids are technically his half-siblings.
- Justified:
- Jason's parents both wanted a large family.
- Jason is part of a blended family in which both of his parents had children before marrying each other, and they may have had kids together in addition to that.
- Jason's parents wanted a son but kept having daughters, or vice versa.
- It's a post-apocalyptic world where the vast majority of the global population has been killed. It's up to the few million survivors to repopulate the Earth, and as a result, massive families are the norm.
- Jason is an ant, or a rabbit, or some other animal that gives birth to large numbers of children at once.
- The story is set before reliable birth control was invented or widely available; families like Jason's are the norm rather than the exception.
- Jason's parents Really Get Around, with a good number of their flings resulting in a lot of half-siblings.
- Jason's parents (perhaps whole family) belong to a religion which forbids birth control.
- Jason's parents have a soft spot for orphans, meaning that some of Jason's siblings are adopted.
- Jason's family are a part of a monarchy. So in order to ensure there won't be a shortage of heirs, having a lot of Spares To The Throne is considered a "safety measure" to prevent a Succession Crisis.
- One or both of Jason's parents had Only-Child Syndrome, so as a result, they don't want any child they have to feel lonely like they did in their childhood.
- Inverted: Jason is an only child, as are the other characters.
- Subverted:
- Jason invites a friend over to his house, and many children are seen inside. Jason's friend Alan asks, "Are they your siblings?", to which Jason replies, "No, they're my cousins. We're having a family reunion, but all the adults are out."
- Jason tells Alan that the children are his other friends, whom Alan has never met for some reason.
- Double Subverted:
- Jason was lying; his "cousins" or "friends" are really his siblings.
- Jason's twenty siblings come home just a moment later.
- Parodied: Jason and his brothers all look identical; he either does not appear to have sisters or they all look like each other as well. And because they all refuse to wear name tags (except Jason himself), the parents are constantly confused over who's who.
- Zig Zagged: ???
- Averted:
- All characters' families are realistic in size.
- No one has any known relatives, period.
- Enforced: "Hey, let's create a really big family. They're always hilarious."
- Lampshaded:
- "You have quite the family, Jason. I've always wanted a family that size."
- "It was difficult for me growing up. Never getting any privacy and all my clothes were hand-me-downs."
- Invoked: Jason's parents both wanted a large family, so they decided to just keep procreating. (And maybe they adopted some of their children.)
- Exploited: When Jason gets in trouble, he avoids his angry parents by disappearing into a crowd of his siblings.
- Defied:
- Jason kills his siblings.
- The parents use birth control so the house doesn't overflow with kids.
- Discussed: "No, my sister Carol is the only sibling I have. When I said we were one big happy family, I didn't literally mean it."
- Conversed: "Look at the size of that family. It's a wonder that they know who's who."
- Implied: A large crowd of children is seen in Jason's house, though it is never explicitly stated that they are his siblings.
- Deconstructed:
- Jason's parents both have well-paid jobs, but because the family is so large, they still don't have enough money to make ends meet.
- The quantity of children makes it impossible for Jason's parents to emotionally support all their children sufficiently; either they give more attention to some than they do to others, or they give all their children very little, but equal, attention. This leads to Jason and some of his other siblings having low self-esteem and an inferiority complex, or being constantly desperate for attention from other people.
- Reconstructed:
- Jason's mother wins a multimillion-dollar lottery, and the family finally has enough money ... at least for now or that she can manage it properly.
- Jason and his siblings all help out around the house any way they can, and the siblings who are old enough all hold jobs and assist with the family's expenses.
- Played For Laughs:
- Some of Jason's siblings have to sleep outside because they don't all fit in the house.
- It is implied that Jason's mother cheats, as some of her children are Chocolate Babies.
- Played For Drama: Jason is The Unfavorite and has Abusive Parents.
