This research paper delves into the critical topic of "Assessing Healthcare Access and Utilization Patterns among Vulnerable Populations in India" through a nationally representative survey. The primary objectives of this study were to understand the complex dynamics of healthcare access and utilization among vulnerable segments of the Indian population and to identify key determinants influencing healthcareseeking behavior. Utilizing data from the "National Health and Socioeconomic Survey (NHSS)," a comprehensive analysis was conducted, focusing on demographic characteristics, education levels, socioeconomic status, regional disparities, and the impact of health insurance. The data analysis tools included descriptive statistics, inferential statistics, logistic regression, and geographic mapping. Key findings from this research include demographic insights into vulnerable populations, variations in healthcare utilization by age group, the influence of socioeconomic status on health insurance coverage, regional disparities in healthcare access, and the critical role of primary healthcare quality. The study also identified financial constraints as a significant barrier to healthcare access among vulnerable groups. The implications of these findings are far-reaching. They provide valuable insights for policymakers, healthcare practitioners, and stakeholders to develop targeted interventions that can bridge healthcare disparities, promote equity, and improve healthcare access for all vulnerable populations in India. By addressing these challenges, India can work towards achieving universal healthcare coverage and ensuring that no one is left behind in accessing essential healthcare services.
