Map #88: April 30, 2018

Difficulty Level: 6

Click here for a full-size version of this week’s map.

This map is a proportional symbol map of North America and Europe. (Do you need a refresher on what a proportional symbol map is? Visit our “Basics” page for a quick primer.) The reason that we have lopped off the other continents besides Europe and North America is because it’s hard to get data from Asia that meshes with the data from Europe and North America. There would definitely be a few dots in Asia, but not all that many. As always, your job is to figure out what this proportional symbol map represents.

Stumped? Check back Tuesday, Wednesday, Thursday, and Friday for hints about where to focus your investigation. The answer will be posted on Monday, May 7, 2018. Good luck!

Tuesday’s hint: Perhaps the first—and most obvious!—thing to notice is that none of the dots on this map are located in inland areas.

Wednesday’s hint: And then the second thing you’ll notice is that many of these dots are in warm, sunny places with lots of great beaches.

Thursday’s hint: The dot that looks like it’s in Rome isn’t actually in Rome—it’s in Civitavecchia. If you intended to visit Rome, under what circumstances might you pass through Civitavecchia to get there?

Friday’s hint: The three big dots in Florida—the three biggest dots on the entire map—represent Port Miami, Port Canaveral, and Port Everglades.
