Population: X, and Counting
In fiction, population signs tend to be updated in real time, whether to reflect new additions, or more often, to reflect a murder spree. A frequent means of establishing a "dangerous Wild West town" setting is a shot of the town sign, with several crossed-out population numbers, indicating frequent reductions due to violent deaths and/or people moving out. A ghost town may be shown with a sign that clocks all the way down to zero that way, presumably updated by the last resident to leave. A specific sub-trope will have a killer be nice enough to peform a community service and adjust the population sign just before or after he offs someone.
- Parodied in a story of the Italian Western parody Pedrito el Drito: a man has just finished painting a population sign when he hears a bang and updates the population. Then a baby is delivered, and the sign has to be adjusted again. Then there's a new shooting... Then the baby turn out to be twins... Then quadruplets... Then the new father commits suicide because he can't support all of them... At last, the painter snaps and axes the sign into chips.
- In issue 2 of Six-Gun Gorilla Tango, a settlement in the Blister, has several crossed-out numbers on the "Welcome" sign on the edge of town, with the last one reading "32?" by the time Blue and the Gorilla get there. In issue 4, Psycho for Hire Auchenbran wipes out the population of the town for consorting with the protagonist, Blue-3425, and is seen writing a big red zero on the sign.
- In South Park: Bigger, Longer & Uncut at the beginning of the "Little Boy, You're Going to Hell" number, we see a sign for Heaven with the counter at only 2500, while a sign for Hell is in the millions and is rapidly increasing.
- The movie Oblivion (2013) establishes its Space Western credentials with a scene in which the bad guy moseys into town and adjusts the population sign to -1... with the blood of his latest victim.
- The population sign was updated several times in My Name Is Bruce, as more and more people were killed.
- This occurs in THX 1138. There was an "Officers in service" counter for robot policemen; after one was in a car crash, the number reduced by a tick.
- Freddy's Dead: The Final Nightmare reveals that whenever Freddy kills he alters the Dream World version of the "Welcome to Springwood" sign to reflect the decreasing population.
- Smalltown, USA in The Muppets has a population sign which flips, seemingly by magic, to keep the population count accurate whenever the main characters enter or leave the town.
- The Postman: The Pineveiw town sign has a population number that has been repeatedly crossed out and re-written, going from 267 to 132 even before the town came to the attention of the Holinists.

- In Battlestar Galactica (2003), the president of the colonies keeps a running tally of the number of humans left alive. Starting from the second season, the opening credits also show this number, updated week-to-week. The number is 50298 in the first episode and 39406 in the last one.
- Notably, near the end of the premier mini-series, there's a moving moment where the president's aide, amidst a flurry of other news and updates from the civilian fleet, informs her that a pregnant woman has given birth. Her face lights up with hope and delight as she takes a moment to savor adding one to the population/survivor tally on display in her make-shift office.

- The town of Fyrestone has a sign like this on the outskirts in Borderlands.
- There was also that incident in Looking for Group where Richard massacres an entire village, and on his way out, he crosses out the population counter on the sign, writing in a '0' instead. Using the blood of his victims as paint, obviously.
