Answer Revised
Answer 10 [CTY] Area and Population
The city fills a roughly 12 mile square (19 km), making it 144 square miles (370 sq km, 92160 acres).
Combining this with
TGLS's revised land use stats and assuming 2.5 people per dwelling gives these figures for the residential areas:
LDR 6.10%; 8.7 sq mi (22.5 sq km); 22,487 dwellings; 56,218 people
MDR 10.15%; 14.6 sq mi (37.4 sq km); 336,753 dwellings; 841,882 people
HDR 14.37%; 20.7 sq mi (52.9 sq km); 4,290,859 dwellings; 10,727,148 people
For a recorded population of 11,625,247 people.
(BTW- This is more than London or Paris, in a fraction of the area. (list))

11 million is probably still a lot, but I can live with that. And there'd be a lot of unlisted dwellings and people, but we haven't got round to that yet.
