text_A: Access to affordable housing and employment opportunities with fair wages and benefits are closely associated with good health. Public health leaders have shown that opulent housing qualities are linked to poor health. As Central Harlem also bears the effects of racial segregation, public health researchers claim that racial segregation is also linked to substandard housing and exposure to pollutants and toxins. These associations have been documented to increase individual risk of chronic diseases and adverse birth outcomes. Historical income segregation via redlining also positions residents to be more exposed to risks that contribute to adverse mental health status, inadequate access to healthy foods, asthma triggers, and lead exposure.
