U.S. government infant-mortality data are done by the National Center
for Health Statistics. The NCHS receives a sampling of death
certificates, which include the race of the person, from all 50 states
and DC. The NCHS notes that racial breakdowns in mortality statistics
should be treated with caution, since the race recorded might not
always match the races a family considers its members to be. Studies
show that some Asian people are incorrectly listed as white on death

Birth statistics are a bit different, as the NCHS gets information
from 100 percent of U.S. birth certificates through the Vital
Statistics Cooperative Program. As far as race goes, the NCHS bases
its birth rates on the race of the mother. Of the birth certificates
the center received in 2002, 99.5 percent included the race of the
mother. From that data, they can divide the number of births by the
total population to get crude birth rate.

Per-capita income data come from the Census Bureau. In the 2000
census, about 1 in every 6 households received the "long-form
questionnaire," which asked how much money the respondants made in
1999 (as well as race, of course). Per-capita income for the Asian
population would be determined by adding up the income totals for all
Asian respondants, converting it from a sample number to an estimated
figure from 100 percent of the Asian population, then dividing it by
the Asian population.
The Census Bureau continuously updates the decennial figures with
estimates. The methodology of the updating is complicated, but it
involves regular surveys of about 75,000 households a month and
keeping track of birth, death and net immigration rates. For more
information on the methodology, see the link below.

The NCHS links above should give you information on infant mortality
and birth rates. You can also try the Census Bureau's Statistical
Abstract of the U.S. at
Per-capita income estimates by race are available in the bureau's
publication "Income, Poverty, and Health Insurance Coverage in the
United States: 2003," which is available at (Income, Poverty, and
Health Insurance Coverage in the United States: 2003). For access to
