[Dawn of the Dead, 2004] What is the state of the world in present day 2018? Are there survivors, or are there zombies everywhere? Have they rotted away?

I don't believe they specify the date, but Romero's Land of the Dead is pretty much a solid representation of what Dawn of the Dead's future would look like; relatively small human enclaves have managed to elevate themselves to city-state status, with the surrounding land populated with still-mobile zombies. Actual big hordes are pretty freak occurences, so the z's typically don't have the weight of numbers to breach the strongholds, and the strongholds are equipped to raid the landscape, but lack the guns and the numbers to expand their land. As such, they've settled into an equilibrium.

City-state contact is chiefly by radio, and mostly concerns exchanges of relevant intel (reports of severe weather, any contact reports with potentially dangerous zombie hordes, etc.). Actual physical contact between the cities either involves water travel or a dangerous overland voyage, limiting commerce and population exchanges. 

The zombies themselves, short of much stimulation, have settled into rote routines of their former lives. Barring the ever-rarer sightings of actual humans, they exist in a limbo, trapped in one of the few moments of actual life they can still recall.
