NOTES: Net undercount is the difference between the estimate (A.C.E. or PES) and the census, divided by the estimate. Minus sign (–) indicates a net overcount. For 2000, total population is the household population; for 1990, it is the household population plus the noninstitutional group quarters population (see Appendix C). The 90% confidence interval is the estimate plus or minus 1.645 times the standard error of the estimate. See Table 6-2 for definitions of race/ethnicity domains in 2000. N.A.: not available (not estimated).
