👉 The term "microbarogram" is a method used in epidemiology to study the incidence or prevalence of diseases at a small scale, often involving sampling and statistical analysis. It involves isolating a sample from a larger population to examine its characteristics such as age distribution, sex ratio, and other demographic factors. The results are then compared with those obtained from a larger sample to estimate the overall prevalence of the disease. This method is useful for understanding the incidence rates in specific geographic or environmental areas.
