President Trump was justified in calling Baltimore “rat infested.” It came in 9th in a list of most rat-infested cities. To be fair, Baltimore has shown some improvement. Last year, it was #8; two years ago it was #6.
N.b., the +1 and -1 etc. notes show each city’s shift in place from previous year’s report. E.g., Chicago held on to its #1 Rattiest City spot from last year, LA switched places with New York City, DC switched places with San Francisco, etc.
