Neither the article nor the blog post actually explain this, but it's irking me: what are the six territories? The United States has five populated territories: American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The United States Minor Outlying Islands include Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Island, Navassa Island, and Palmyra Atoll, but those don't have permanent populations. Are they counting Washington, D.C. as a territory here?
