Understanding the epidemiology of sarcoidosis is essential for the assessment of the broader impact and distribution of this enigmatic disease. Sarcoidosis exhibits significant variability in its prevalence and presentation across different populations and geographic regions worldwide. This chapter explores the epidemiological patterns of sarcoidosis, highlighting its incidence, prevalence, and demographic factors such as age, gender, and ethnic predispositions. By examining these factors, we aim to uncover the diverse epidemiological landscapes that shape our understanding of how sarcoidosis manifests and affects individuals globally.
