Among these fluidly changing geographical boundaries and areas sought by a segment of the population of the Northwest are the following Pacific Northwest proposed states and separatist movements:   The Pacific Northwest has the lowest rate of church attendance in the United States and consistently reports the highest percentage of atheism; this is most pronounced on the part of the region west of the Cascades. A recent study indicates that one quarter of those in Washington and Oregon believe in no religion. Similarly, according to the 2011 National Household Survey, 44% of British Columbia residents reported no religion. Religion plays a smaller part in Pacific Northwest politics than in the rest of the United States. The religious right has considerably less political influence than in other regions. Political conservatives in the Pacific Northwest tend to identify more strongly with free-market libertarian values than they do with more religious social conservatives. That said, three of the four major international charities in the region are religious in nature: World Concern, World Vision International, and Mercy Corps. This is part of a long tradition of activist religion. The Skid Road Group, a shelter offering soup and sermons to the unemployed and recovering alcoholics, was launched in Vancouver, with the Salvation Army having deep roots in the Gastown district, dating back to the era of the construction of the Canadian Pacific Railway (1880s) and attained prominence in the same centers during the Klondike Gold Rush. The region is also known as a magnet for a wide range of philosophical and spiritual belief systems. Eastern spiritual beliefs have been adopted by an unusually large number of people (by North American standards), and Tibetan Buddhism in particular has a strong local following. The Northwest Tibetan Cultural Association, claimed to be the largest organization of its kind in the world, was founded in Portland in 1993. The region is home to many unique Christian communities, ranging from the Doukhobors to the Mennonites. The Mennonite Central Committee Supportive Care Services is based in the British Columbia city of Abbotsford. The Mennonite Central Committee and the Mennonite Disaster Service enjoy a heavy rate of enlistment and donations from the strong Mennonite community in British Columbia's Fraser Valley. The Doukhobors, whose church is the Union of Spiritual Communities of Christ, are a Russian Anabaptist sect whose migration to Canada was aided by Count Leo Tolstoy, and who are today focussed in the West Kootenay and Boundary regions of Southeastern British Columbia. Their history in Canada includes resistance to state education and industrial development (see Sons of Freedom).
