Despite being ethnically and religiously diverse, we found that the U.S. experiences a holiday increase that is present across most urban communities,” Miguel Roman, a research physical scientist at NASA Goddard and one of the leaders of the study, said in a news release. “These lighting patterns are tracking a national shared tradition.”
