The United States of America is a country in North America. It is the primary setting for all of The Walking Dead, and a major part of Fear the Walking Dead. It is bordered to the south by Mexico and to the north by Canada.

Pre-Apocalypse

Considered to be the only world superpower left after the end of the Cold War, the United States was an economic powerhouse and a world leader in technology and entertainment, among many other areas.

Post-Apocalypse

From information gleaned from the show, the United States appears to have been the origin for the (eventually global) outbreak, with no reports in any other country before the initial outbreak in the U.S.

It appears that the outbreak in the U.S. began west of the continental divide and spread eastwards across the continental United States, as well as northwards into Canada and southwards into Mexico. (It should be noted that a portion of a newspaper which was released in promotional material for Fear the Walking Dead seems to indicate minor infections nationwide with one or two individuals involved. This would fit with what Shane said about it appearing in isolated locations).

The initial responders to the crises were local law enforcement agencies such as the California Highway Patrol and the LAPD, as well as field offices of the CDC. Once it became apparent that local law enforcement was unable to handle the situation, National Guard Units were deployed (this would change to regular army units as the epidemic moved eastward). However, lack of information about the infection itself and those it affected led to these organizations gradually being overrun.

The leadership of the U.S. Military (and it is assumed, high ranking members of the Federal Government) devised Operation Cobalt in order to try and control the outbreaks. First was the establishment of "Safe Zones" within major population centers with a view to use them as springboards to reclaim infected territory. The establishment of safe zones was followed by quarantine of suspected infected individuals (and their termination if infected, with their bodies being burned). If these measures were to fail, then the final step was the large scale bombing of major urban areas to kill the infected. The bombing of Los Angeles was seen in the first episode of Season 2 of Fear the Walking Dead. The bombing of other areas was confirmed by George Geary or witnessed by other survivors (such as Shane and Lori witnessing Atlanta being bombed).

It is unknown if the unnamed military camp was a part of Operation Cobalt, but it apparent role as a camp for survivors would indicate it was.

By the beginning of Season 2 of Fear, it is unknown how many states have been infected, with some reports at this point claiming between eleven and thirteen states have declared emergencies.

Outbreaks at the beginning of Season 2 of Fear (black are known outbreaks, red are suspected).

According to the last broadcast from the Park Ranger at Shuteye Peak, the bombing of major cities has had major ecological consequences (at least in the California area. By his estimation, the fires caused by the bombing of Los Angeles and other California cities will wipe out the forests of Yosemite and the Sierra Nevada mountains within a week.[1]

In the Fear episode North, it can be seen that there are still individuals guarding the U.S. border with Mexico. It is later revealed that these are members of Jeremiah Otto Sr. survivalist group and were not sanctioned by whatever remains of the government.

By Season 3 of Fear the Walking Dead (roughly about the time Rick Grimes awakes from his coma), it has been confirmed through independent sources that all of mainland America (and the rest of the world) has been overrun by the walker epidemic. At this stage, it would appear that all local law enforcement agencies and the U.S. Military (apart from scattered outposts) have ceased to function. It is unknown whether or not the federal government has ceased to function- it is implied that the Continuity of Government plan was put in place, owing to a broadcast by a citizen. If elements of the federal government did ​survive, then they are in such poor shape that they cannot govern.

As was seen by several characters, particularly Lydia, the Federal Emergency Broadcast System was activated. It ran for roughly twenty three/twenty four days on a loop, before being discontinued and being replaced with a repeating message to "Please stand by." It is unknown who, or by what means, this change was made.

The only known member of the federal government who survived until after the apocalypse is Deanna Monroe.

Several years after the outbreak, the infrastructure in some parts of the country (roads, bridges etc) is in such poor shape as to be on the verge of uselessness to the survivors. In other areas, the infrastructure is showing only mild dilapidation.
