Welcome to my newsletter and blog, Health and Healthcare Data Unleashed, a guide to understanding, presenting and using health and healthcare data, information and evidence. I’ve been writing and posting here since 2010 on a range of topics and resources I’ve encountered in my own data analysis and data visualization journey. You will notice a gap beginning in 2020 as I took time away to work on my book, Visualizing Health and Healthcare Data – I hope you’ll check it out!
