and an unemployment rate of 7.2%. For many years the timber industry dominated Arcata's economy. Today the majority of Arcata jobs come from government (including schools and Humboldt State University), the city's many owner-resident small businesses, some lumber and food manufacturing, and a wide variety of service industries (ranging from professional services to restaurant and hospitality). A large but unmeasurable cannabis economy employs many in Arcata and the surrounding area. The area's economy and population are both growing more slowly than the State of California overall.

The political leanings of Arcata are diverse. Arcata is a hub of liberal thought typical of a college town. Environmentalism and most liberal causes are prominently embraced. The area also is home to commercial fishermen and those in the timber industry who tend to follow a more conservative philosophy. but the decline of both industries has reduced the power base for conservative agendas. The college students and staff as well as old hippies and the current generation of neo-hippies provide the strongest political influences. Arcata was the first city to elect a member of the Green party to an office. The City Council, and at times even the mayor, is composed in part by college students.
Arcata also features a large number of original Victorian structures, many of which have been restored, and is home to the Minor Theater, one of the oldest movies-only theaters in the United States which is still in operation.
The Wiyot People and Yurok People lived in this area prior to Russian and European arrival. "Kori" is the name for the Wiyot settlement that existed on the site of what would become Arcata. The natives of this region are the farthest-southwest people whose language has Algonquian roots. The traditional homeland of the Wiyot ranged from the Little River in the north and continues south through Humboldt Bay (including the present cities of Eureka and Arcata) and then south to the lower Eel River basin. The traditional homeland of the Yurok ranges from Mad River to beyond the Klamath River in the north. Due to several factors, including the effects of disease and the loss of traditional sources of food, their population was reduced to less than 5% of pre-European numbers. The Yurok managed slightly better. The native languages of all local tribes have been almost completely lost and the tribes are no longer truly distinct groups.
The Yurok Tribe was granted fishing rights on the lower Klamath river as salmon and steelhead are traditional foodstuffs for them and of great cultural significance.
In August 1989, the voters of Arcata passed the Nuclear Weapons Free Zone Act, prohibiting activities benefiting nuclear weapons contractors within city jurisdictional limits.

On January 4, 2006, the Arcata city council adopted the New Year's Resolution, demanding the impeachment or the resignation of President George W. Bush and Vice President Richard B. Cheney for violations of Constitutional and International law, making it the first city to pass such a resolution. This is the second time the City Council has passed a resolution calling for the impeachment of President Bush.
The Arcata Marsh has multiple uses including recreation, wildlife habitat, education, and wastewater treatment. In 1996 Arcata elected the first-ever Green Party city council majority. This majority was lost two years later, restored in 2004 and lost again in 2006.
State Route 299 connects to U.S. Route 101 at the northern end of Arcata. SR 299 begins at this point and extends easterly towards Weaverville, Redding, Alturas, and Nevada.The highways connecting Arcata to areas outside Humboldt County contain long segments of winding two-lane road traversing remote mountains and river canyons, portions of which can become closed after extensive rain and wind storms, necessitating sometimes very long detours. Arcata, Eureka, Fortuna and the Redwood Coast region is one of the most remote locations along the continental US west coast.

The community has been active in saving the Headwaters Forest from logging. The effort to save the Headwaters Forest in the 1990s resulted in the arrests of hundreds and strained Humboldt County's abilities to deal with the protesters who trespassed, littered, and left human waste throughout the forests, peoples yards, and highway right-of-ways. Some of the more militant environmentalists also drove steel spikes into trees belonging to the lumber companies as a way to discourage logging by creating a serious safety concern. A logging protester, who was trespassing, was accidentally killed by a falling tree.
