Earth's is 101,000 Pa dropping to 30,000 on top of mount Everest. Mars's mean surface pressure is around 600 pascals which is below waters triple point which prevents water from forming regardless of temperature. http://en.wikipedia.org/wiki/Triple_point Still that's close and in some creators the pressure increases high enough so it's possible for water to form.
Unfortunately, on top of that what makes the atmosphere truly deadly is a lack of Nitrogen one of the primary building blocks for organic chemistry.
First, there's already an established Asian community that has been here for a long town. There are old Chinatowns, Little Tokyos, etc. There's no Little Nairobi that I've ever heard of. So many Asians aren't actually recent immigrants.
Second, regarding those who are, many Asians aren't here by merit alone. Sure, there are some (like my parents) who came from a poorer background and managed to make it to the US. But increasingly they are supplemented by people who were born into rich families (fu er dai, "second generation rich people"). Now, I don't have statistics to back this up, but this seems to be more prevalent now because of China's recent economic boom. It's just my own theory, anyway.
Also, if you were to visit some Chinese social event (church for example), there are distinct groups of people. It's not just middle class white collar workers, there are also lower class people and older people. There are multiple generations, from the older people (mostly Cantonese speaking, at least where I live), to the middle aged people, to the young people (either ABCs or international students).
They did something like that for a day on Italian Wikipedia when they discussed in the Italian Parliament a law which, in the case when someone is offended (even if the facts are true!), if a website doesn't respond in 48 hours to the request of removal, the website would have been given a 10,000 euro fine.
The population growth rate is decreasing (the average number of children per woman is down from 5 in the 1950s to 2.5 today) and in much of the industrialized world, it's already going down.
The population is still increasing, but much of it is no longer due to a high birthrate but due to an increase in lifespan.
