This chart, from David McCandless' fascinating new book Knowledge is Beautiful, ranks 87 dog breeds and compares those rankings to the actual popularity of the breeds in the US.

The ranking is based on a number of factors: trainability, life expectancy, lifetime cost (including the price of food and grooming), and suitability for children, among others.

The result: Border Collies, according to McCandless, are the finest dog breed in existence. Labs, Beagles, and Golden Retrievers, while not at the very top, are other popular dogs (at the top right of the chart) that he rates highly.

On the other hand, the formula seems to penalize big dogs. German Shepherds, Great Danes, and Saint Bernards, all in the top left quadrant, are in McCandless' words, "inexplicably overrated." The formula also uncovers some overlooked breeds, at the bottom right, that should be more popular, like Border Terriers and Pointers.

Finally, on the bottom left, the chart shows the breeds that are unpopular and properly so: Old English Sheepdogs, Borzois, and Afghan Hounds.

Poor, poor Afghan Hounds:

Hat tip to Slate for finding the chart. Bonus points if you can spot the easter egg in it.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple reasons that we can't rely only on ads and subscriptions to keep the lights on.

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. We can’t do that if we have a paywall.

That’s why we also turn to you, our readers, to help us keep Vox free. If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today?
