Big Water Consulting partnered with United Way, Pyramid Communications, King County, and the Urban League to form a coalition designed to work with local community based organizations to better target community outreach and increase 2020 Census self-response rates in King County and Washington State. The work is funded by a grant from the Washington State Office of Financial Management. In addition to providing training to United Way Census Navigators who will provide information and assistance concerning the 2020 Census at 33 tax preparation locations in historically undercounted areas in King County, Big Water is creating an online map including predicted self-response data as well as live self-response data that will help partners target efforts in communities that may be at risk of having low self-response rates.
