Summary
Ecological fallacy is a failure in reasoning in epidemiology when an inference is made about an individual based on aggregate data for a group. This can be seen in studies such as studies between nativity and literacy, diet, lifestyle, heart disease, and stroke, and when the aggregate data is used to calculate the correlation, details about individuals may be missed. To avoid ecological fallacy, it is important to consider the heterogeneity of correlations among the cohorts and to use individual data to determine the true association.
