Geographically intelligent disclosure control for flexible aggregation of census data
نویسندگان
چکیده
This paper describes a geographically intelligent approach to disclosure control for protecting flexibly aggregated census data. Increased analytical power has stimulated user demand for more detailed information for smaller geographical areas and customized boundaries. Consequently it is vital that improved methods of statistical disclosure control are developed to protect against the increased disclosure risk. Traditionally methods of statistical disclosure control have been aspatial in nature. Here we present a geographically intelligent approach that takes into account the spatial distribution of risk. We describe empirical work illustrating how the flexibility of this new method, called local density swapping, is an improved alternative to random record swapping in terms of risk-utility.

متن کاملStatistical Disclosure Control: New Directions and Challenges
Traditionally, statistical agencies generally release outputs in the form of microdata and tabular data. Microdata contain data from social surveys and tabular data contain either frequency counts, such as for census dissemination, or magnitude data typically arising from business surveys, eg. total revenue. For each of these traditional outputs, there has been much research on how to quantify ...
