This working paper reports the findings from an analysis of the estimated undercount of the population in the 2000 Census for Los Angeles County. The Bureau of the Census improved its performance for 2000 relative to 1990, but the enumeration was not complete. The are three key findings: 1) Los Angeles County has a disproportionate number of the undercounted population; 2) the undercounted population is unevenly distributed within Los Angeles County across neighborhoods, varying across neighborhoods from -0.3% to 5.9%; and 3) neighborhoods with the highest under-count rates tend to be poor and predominantly minority, and have a relatively large number of children. Because of the geographic differences, disadvantaged neighborhoods and populations are at risk of being under-represented, under-served, and under-funded.
