Let's compare the families in three of my household's favourites: The Simpsons, Family Guy and The Goldbergs:
Homer, Peter, Murray
Fat slobs in not very exciting or ambitious jobs. Politically disinterested and very politically incorrect and undiplomatic. Very lax approach to parenting. It is never clear why they got married and had children in the first place but they love their wives by default, by force of habit as much as anything.
Marge, Lois, Beverley
Full time housewives. Relatively attractive. Married beneath themselves but seem to love their husbands - it is never quite clear why. More politically aware: Marge is more Democrat and Beverley is more Republican. Pushy with their husbands and ambitious for their children.
Bart, Chris, Barry
The first-born son. Do badly at school, lazy around the house but adventurous or at least in their own imaginations. Bully their younger siblings.
Lisa, Meg, Erica
The firsts-born daughter. Look down on the rest of their family and are bullied by them. Do well at school. Politically engaged, ready to take up left wing causes like the environment etc.
Maggie, Stewie, Adam
The youngest child/the baby. Maggie just an eternal baby. Stewie is an evil genius and Adam is a documentary film maker, but both have rich fantasy lives.
