How is "city" defined, for the purposes of this metric? Is it the administrative boundaries of Jakarta according to Indonesian law? The catchment area where a large fraction of people commute to the city center? Something else?

I was wondering the same. I guess it comes from this "UN figure":

> The UN figures include a mixture of city proper, metropolitan area, and urban area.

https://en.wikipedia.org/wiki/List_of_largest_cities

I haven't looked into the details of that definition.

But there is a somewhat standard definition to "metropolitan area" derived from something like "area where there is at least X per square km"

So it's not related a somewhat random definition of a "city" and its borders.

		If you find a better link for the methodology please let me know. But simplified it's maybe exactly this from the UN reports glossary: > Cities: According to the Degree of Urbanization methodology, contiguous geographic areas with a high population density (at least 1,500 people per km2) and a total population of at least 50,000 inhabitants. https://www.un.org/development/desa/pd/sites/www.un.org.deve...
