"This study compares the 1990 [U.S.] population estimates of four national demographic data vendors with the actual counts of the 1990 Census. It was performed for a consortium of three public utility companies [in California].... In addition to total population, this study evaluates the estimates of three other demographic variables...: number of households, population of Spanish origin and white population.... Differences in accuracy are found among the vendors and between variables.... On average, the estimates were most accurate for total population, considerably less so for race (white population) and households and by far the least accurate for Hispanic population."
