The research question is: across the United States, how does the lack of healthcare access due to cost and the racial makeup of each state impact the number of cancer deaths per 100,000 people? This question highlights the fact that in the United States there are large wealth and income disparities between white and BIPOC populations, and that healthcare, and more specifically cancer care, is incredibly expensive. hypothesis arrow diagram is income inequality (+) -˃ access to healthcare due to cost (+) -˃ cancer deaths I need a literature review done on studies about Cancer and income inequality, access to healthcare and race.
