The West Pacific States form one of the nine geographic divisions within the United States that are officially recognized by that country's census bureau.[4] There are five states in this division – Alaska, California, Hawaii, Oregon, Washington – and, as its name suggests, they all have coastlines on the Pacific Ocean (and are the only US states that border that ocean). The Pacific States division is one of two divisions of the United States Census Bureau's Western region, the other being the Mountain States.
