Excess Deaths February Update
The CDC continues to update its counts of deaths by cause for 2020 as data comes in from the jurisdictions that report to it. The data are by now fairly complete, though there are still significant gaps in several states due to delayed reporting. North Carolina, in particular, has yet to report almost any deaths for the entire final quarter of 20...

I revisited the Partisan Trajectories graph, as it seems there’s more that could be done with it. More on that in the future, I hope.

Comparing Distributions
When we want to see how something varies across categories, the trellis or small multiple plot is a good friend. We repeatedly draw the same graph once for each category, lining them up in a way that makes them comparable. Here’s an example from my book, using the gapminder data, which provides a cross-national time series of GDP per capita for...

For the past view years, Jason Snell at Six Colors has conducted a survey of people who write about Apple. He asks a series of questions about the company and its products and presents a report of people’s answers. This year’s report has all the details for those interested.
