Founded in 2009, the nonprofit independent TucsonSentinel.com has a mission of informing Southern Arizonans about the community challenges and unique culture of our borderlands, and public policy responses to them: “A smarter Tucson is a better Tucson.” The TucsonSentinel serves readers in metro Tucson (pop. 1M), the rural stretches of Pima County, and the other border counties of Santa Cruz and Cochise. Those in our coverage area are often poor and include many new/recently moved residents; 29% of adults speak Spanish or another language at home. Two Native tribes have reservations bordering Tucson: the Pascua Yaqui Tribe and the vast Tohono O’odham Nation. The Sentinel has published numerous investigations that have led to immediate changes in government policies and legislation.
