An explanation of the race and Hispanic origin categories used in this table can be found at www.census.gov/population/estimates/rho.txt The estimates presented here were produced by a method which is still in a developmental stage. They may not be accurate for populations which are very small or have unusual race distributions and they may not reflect recent changes in the distribution of the population with respect to race and Hispanic origin. These figures should be used with caution.
