Abstract:
|
This paper documents the disclosure limitation protocol for the Census Bureau's "On the Map" application, which manipulates and displays origin-destination patterns and associated worker and business characteristics. The version discussed in this paper consists of a block-to-block commute pattern matrix of jobs and workers in at least one state and associated data on the characteristics of the residence and workplace areas at the block-group level. The disclosure limitation protocol creates synthetic origin/residence data using the posterior predictive distribution of the workers' place of residence conditional on estimates of employed workers that have been protected using the noise-infusion disclosure limitation protocol from the Quarterly Workforce Indicators.
