Many studies have identified socio-economic status as a major factor affecting health. Christopher Richardson is narrowing the focus to look specifically at the relationship between socio-economic status, mental health and health care usage. This study involves the use of sophisticated statistical technologies to analyze data from National Population Health Surveys on factors affecting health such as education, income and mental health. Richardson hopes this work will lead to a better understanding of mental health and the ability to more precisely measure mental health and its connection to health care usage.
