I often refer back to this data set when looking for statistics on the history of global living conditions. In times like these we sometimes need something positive to look at, and how far we have come. But as we have learned, history does not always predict the future. It will be interesting to see what impact COVID-19 has on the future of global health as we know it.
One of the more interesting stats from the data:
In 1997, the child mortality rate (< 5) was 8.37%, in 2017, it was 3.91%.
