Hong Kong has one of the highest population densities in the world—more than 6,350 persons per km2 (more than 16,400 per mi2).
Roughly 98% of the population of 6,940,432 (2006 est.) are Chinese; the majority of them have their family origins in Guangdong
province.
There are also significant numbers of Europeans and Americans, Filipinos (mostly domestic servants), and Indians
and Pakistanis.
About 60,000 Hong Kong residents emigrate each year, mainly to North America or Australia.
This outflow is
more than counterbalanced by legal and illegal immigration from China.
