Dataset: Life Expectancy

The life expectancy dataset is comprised of cross-country data from the World Health Organization (WHO) about average life expectancy and related health factors for 2015. The first column consists of the average life expectancy (in years) and the following columns contain fields such as infant mortality, GDP, and BMI. This dataset was originally adapted from this Kaggle Dataset which contains data over several decades. Note the source dataset contains considerably more columns than are present here, but many of those contained rows with missing (unknown) values which our data loader cannot handle.
