which type of movement has occurred significantly in Washington over the last 50 years?

One significant type of movement that has occurred in Washington over the last 50 years is urbanization and the subsequent growth of metropolitan areas. As more people have migrated from rural areas to cities, there has been a rapid expansion of urban communities and development of housing, infrastructure, and amenities to accommodate the increasing population.
