The Low-Income Southern States Survey series from the Harvard T.H. Chan School of Public Health is now available in the archive. Conducted by SSRS, this series provides valuable insight into the healthcare experiences and attitudes of low-income Americans living in the South. The first, second, and third waves in the series surveyed low-income adults residing in Arkansas, Kentucky, and Texas. Respondents answered questions about topics such as health insurance coverage, healthcare provider experiences, preventive care, Medicaid, and the Affordable Care Act. In November and December 2016, SSRS conducted the fourth and most recent wave in the series. Wave 4 sampled 2,951 low-income adult residents of Arkansas, Kentucky, Louisiana, and Texas ages 19-64. As with the previous waves, it includes a variety of questions about healthcare and personal health.
