Mark Nowlin of the Seattle Times crafted this infographic based on data from the RLB Crane Index. It illustrates which cities have the most construction cranes. Per the infographic, Seattle had the most cranes with 62 as of January. Chicago was a close second with 56 cranes. Other cities listed on the map include Washington D.C., Boston, New York, Austin, Denver, Phoenix, Los Angeles, Honolulu, San Francisco, and Portland. By showing how many cranes are currently working in a city, readers can infer how quickly the city is being developed. Those developing quickly, like Seattle and Chicago, may also be experiencing population growth.
