I’ve always been fascinated by visualization of data, especially data representing interesting and important characteristics of our world. I read a book recently called “The Leading Indicators: A Short History of the Numbers That Rule Our World,” by Zachary Karabell. In this book, Karabell talks about how leading economic indicators such as gross national product are both useful and misleading. Many times metrics that were developed for one purpose are used for another with unintended consequences. What gets measured gets managed. This book also pointed me to an interesting website called gampinder where you can download a desktop program containing data on a wide variety of global trends. It is a fun program to visualize what is going on in the world. If you have some free time, I highly recommend checking it out.
