^ Looks like they only account for the "urban" area based on their "about" and the map but I am not sure how they define such an area as it goes out for miles from the city center in several corridors. Obviously, the numbers cited for the overall City are way low compared to actual.

How do we define city boundaries? To define city boundaries, Metroverse uses spatial entities called "urban centres". Urban Centres are defined by specific thresholds on resident population and built-up surface share in a 1x1 km uniform global grid. While this methodology has the benefit of defining cities consistently, across geographical locations and over time, it may result in boundaries that are slightly different than administrative city boundaries.
