“A 2010 Health Needs Assessment for 15 counties of the Coastal Bend in the state of Texas indicates limited access to health care services and health insurance coverage is a main potential barrier to health care for some segments of the Coastal Bend population. The purpose of this paper is to obtain geographical sight of the health insurance coverage. The hypothesis is that the health insurance coverage by racial and ethnic groups would vary spatially. Data came from the local hospital systems and included 145,669 patient visits from 1 September 2007 through 31 August 2009. A series of maps were produced showing financial class categories for both Hispanics and Whites adults by combining the cross-tabulations of patient data and estimated population both at the zip code level. The maps show that the health insurance coverage disparities vary spatially within zip codes in the Coastal Bend. Moreover, Hispanic and White adult patients do not follow the same pattern of spatial distribution.”
