The series focuses on Cricket Green, a mischievous and optimistic country boy who moves to the Big City with his family. Cricket’s curiosity and enthusiasm leads his wildly out of place family on epic journeys, and into the hearts of his new neighbors.
Episodes currently air on Disney Channel, with reruns on Disney XD.
10-year-old country boy Cricket Green and his family move to the Big City to live with Gramma Alice. There, he and his 12-year-old sister Tilly meet and make new friends, including new best friend Remy Remington, cafe co-worker and friend Gloria Sato and others. While getting used to his new surroundings, Cricket tries to make the most of his time in Big City, while learning new morals along the way.
The series was created by Chris and Shane Houghton, who originally worked on Nickelodeon's Harvey Beaks. Along with the Emmy Award-winning director Rob Renzetti (creator of My Life as a Teenage Robot, supervising producer for Gravity Falls and executive producer of the 2017 reboot of DuckTales) serves as executive producer and the Houghton brothers serve as co-executive producers.
The series (originally titled Country Club) was greenlit by Disney in 2012., just before they contributed their work on Gravity Falls and then for Nickelodeon’s Harvey Beaks in 2015.
Initial production of Big City Greens took place between 2014 and 2017.
Following about a year after its announcement, on July 21, 2017, an official main title was released on Disney XD YouTube channel, with the series being renamed from Country Club to Big City Greens.
In late November, a sneak peek of the series was unveiled and shown at the CTN expo. 
On April 2, Chris announced via Twitter that the series had moved from its original channel, Disney XD, to Disney Channel  for the Summer 2018 season.
A second season was greenlit ahead of the show's premiere. In addition to the series' renewal and subsequent June 18th premiere, there were guest voices planned for the show. This included Jon Hamm, Raven-Symoné, Busta Rhymes, Danny Trejo, Lorraine Toussaint, Jim Rash, Paul F. Tompkins, Lauren Lapkus, Andy Daly, Scott Aukerman, McElroy, Paul Scheer, Zeno Robinson, Colton Dunn and Anna Akana.
On June 7th, the series was being promoted at the Pixar Fest, alongside the then-upcoming Pixar film, Incredibles 2.
In addition to a 46-second sneak peek, ComicBook revealed that the series premiere was made available on DisneyNOW beginning Friday, June 8, ten days ahead of its airing.
With "Space Chicken" and "Steak Night" being the first two episodes to air, the series premiered with a week of new episodes June 18-22, as part of Disney Channel’s GO! Summer programming event. Throughout the summer season, new episodes premiered Monday and Wednesday mornings (10 a.m.), with additional shorts premierieng Saturday, June 16 on Disney Channel and its YouTube channel.
In addition to this, DisneyNOW released its first multiplayer game and first game based on the series, Big City Battle!, where players compete against each other to earn their place as a member of the Green family.
On December 10th, the series won the CommonSense seal of approval. 
The series name was originally titled Country Club.
The series was originally going be aired in 2017, but ended up being postponed into 2018 while another show, Billy Dilley's Super-Duper Subterranean Summer, (which originally was assigned for 2018) ended up taking its place for the 2017 release.
The theme music was performed by a band group named "The Mowgili's".
Although the series generally starts with the opening theme, the double-length episodes start with a cold open, similar to Disney Channel's live action shows and older Disney Channel cartoons, as well as some of Big City Greens' sister cartoons such as Gravity Falls.
The main characters have yellow skin, while the background characters have colored (e.g. purple, red, green, yellow, blue) skins rather than normal human skin color. This contrasts with The Simpsons where almost all characters have yellow skin.
The reason why the Big City Greens main characters are yellow is because the Houghton brothers worked together on Simpsons Comics.
It is unknown why the other characters have varying colors of skin tones (a'la Doug).
Some of the characters lack a nose; this is very similar to the Moonins and some characters from Adventure Time and South Park, whose characters also lacks a nose.
Originally, the series was going to air on Disney XD, but moved to Disney Channel.
However, syndicated reruns do air on Disney XD.
The series was listed as #4 of 10 Animators to Watch 2018.
Cricket and Tilly are the only characters that have appeared in every episode of the series and shorts.
The only Big City Greens media Cricket does not appear in is "Tilly's Cats" (only appearing in the title card and ending segment on YouTube).
