SOURCE: Estimates obtained from models are applied to CPS data. Model inputs also include Census 2000, intercensal population estimates, and administrative records data. For information on the data sources, measures of uncertainty, confidentiality protection, and sources of error, see SAHIE source and accuracy.
The 90-percent confidence interval is a measure of an estimate's variability. The larger the confidence interval in relation to the size of the estimate, the less reliable the estimate.
