National Health and Nutrition Health Survey 2013-2014 (NHANES) Age Prediction Subset

Donated on 9/21/2023

The National Health and Nutrition Examination Survey (NHANES), administered by the Centers for Disease Control and Prevention (CDC), collects extensive health and nutritional information from a diverse U.S. population. Though expansive, the dataset is often too broad for specific analytical purposes. In this sub-dataset, we narrow our focus to predicting respondents' age by extracting a subset of features from the larger NHANES dataset. These selected features include physiological measurements, lifestyle choices, and biochemical markers, which were hypothesized to have strong correlations with age.
