A New Way to Look at Regional Survey Data: Differences in Vacancy Rates and Persons per Household by County, 2000-2005

TL;DR

The paper introduces a mapping method for regional survey data that highlights significant differences in vacancy rates and household sizes across all U.S. counties from 2000 to 2005.

Contribution

It presents a new visualization approach that displays survey estimates and significance levels simultaneously for all U.S. counties.

Findings

Maps show significant differences in vacancy rates and household sizes.

Analysts can identify counties with notable survey estimate differences.

Method allows focus on significant data while accounting for uncertainty.

Abstract

Regional survey estimates and their significance levels are simultaneously displayed in maps that show all 3,141 U.S. counties and equivalents. An analyst can focus his attention on significant differences (or those with a different, low-valued uncertainty measure) for all but the very smallest counties. Differences between Census 2000 and the 2005 American Community Survey values are shown.
