Worldometers - one cool web site

The image is a screenshot from a website called Live Statistics in the USA. It's related to Worldometers, which provides real time world statistics. There's a screenshot of it, below. Sometimes its fascinating to watch the number of babies born today click up. But there's more to the site than that. There's data transparency. Wondering about that figure of 931 US homicides this year (as of January 22)? If you click on the "Info" button you get this:
[R]ates per 100,000 people are decreasing steadily since 1991, and are now back at the levels of the mid 1960's after being at twice the current rate in the 70's and 80's. Current estimates are based on CDC data.
The CDC link takes you to CDC's Faststats page. As with anything else, you need to do a little thinking: the figure of 931 is a calculation based on the CDC's rate of 5.3 homicides per 100,000 population, 21 or so days into the year.

Here's a screenshot from Worldometers:
