Question: What is the population within the city limits of the city where the company Sibur is headquartered ?
Context: For the majority of cities in North America, the most recent official population census results, estimates or short-term projections date to 2015.  This list compiles figures for all North American cities with a population within city limits exceeding 500,000 that year.  These figures do not reflect the population of the urban agglomeration or metropolitan area which typically do not coincide with the administrative boundaries of the city.  They refer to mid-2015 populations with the following exceptions: Moscow ( or ; Russian: Москва́ , "Moskva"; ] ) is the capital and most populous city of Russia, with 13.2 million residents within the city limits and 17.1 million within the urban area.

It is known as Government Street east of Pinehill Drive and as Government Boulevard west of Pinehill Drive.  It is the most important road on Mobile's far south side and is the only nominally east–west road on Mobile's south side to come into the city from outside the western city limits and reach the downtown business district.  The only other two east–west thoroughfares in the city to do so are Moffett Road/Springhill Avenue and Old Shell Road.  Government is a four-lane highway throughout the city limits, from Water Street to the western city limits.  It is the only thoroughfare in Mobile to have intersections with both Interstate 10 and Interstate 65 within the city limits.
