Albuquerque could have a big boost in population during the next five years, according to an American City Business Journals On Numbers report.

Fifty-two U.S. metropolitan areas currently have more than 1 million residents. Tucson, Ariz., was the latest to join the million-plus club, crossing the threshold just five months ago.

But it won’t be the last entry. On Numbers has identified 28 other metros that have a decent shot at reaching a population of 1 million by 2050.

The closest to that goal are Honolulu, Fresno, Tulsa and Albuquerque, according to the report.

Honolulu should get there first. It’s Jan. 1, 2013, population was 976,894, based on On Numbers’ latest estimates. If its recent growth patterns continue, Honolulu will reach 1 million on July 28, 2015.

Albuquerque is expected to grow from 918,876 at the start of 2013 to 1 million on Sept. 21, 2018.

On Numbers has developed a computer program that analyzes more than a decade’s worth of demographic data to project the populations of states, metropolitan areas, counties and cities at any given moment.
