Asian-Americans: Not homogenous, Income of Korean-Americans

I wrote earlier that:

Though here, and it may come off as a surprise, but according to I believe the 2000 U.S. Census Data, Korean-Americans are actually the poorest income "group" among Asian-Americans.

And, I've found the data. It's actually a report from the U.S. Census Bureau entitled, "We the People: Asians in the United States" (the full file can be found here and the link is also in the Selected Articles part as you scroll down on your left hand side). I've taken a photo of the graph and circled the relevant portion in red. While definitely, not the poorest, it does show that Korean-Americans are the poorest among Northeast Asians and actually have a lower median income than that of all American households, which stands in stark contrast with the fact that the median of Asian-Americans stands much higher than that of all American housholds. Of course, I'm not getting into why this is the case as this doesn't separate the different groupings according to the date of arrival and the like. Specifically, the report says:

This report provides a portrait of the Asian population in the United States and discusses the eleven largest detailed Asian groups at the national level, for example: Asian Indian, Cambodian, and Japanese.1 It is part of the Census 2000 Special Reports series that presents several demographic, social, and economic characteristics collected from Census 2000. The Asian population is not homogeneous. It includes many groups who differ in language, culture, and length of residence in the United States. Some Asian groups, such as the Chinese and Japanese, have been represented in the United States for several generations. Other groups, such as the Hmong, Vietnamese, Laotians, and Cambodians, tend to be comparatively recent immigrants.

Of the total United States population, 11.9 million people, or 4.2 percent, reported they were Asian. This number included 10.2 million people, or 3.6 percent, who reported only Asian and 1.7 million people, or 0.6 percent, who reported Asian and at least one other race. Table 1 shows the number of people reporting a single race from among the detailed Asian groups and a tally of the number of times the group was reported

Anyways, this is a subpoint that I just wanted to get the data for from my main posting: Traits Characteristic of Koreans
