Introduction to topic
 Economic map went
viral in Feb 2014
 Clearly showed U.S.
metro areas as
economic
powerhouses
 But not dynamic
 What does it mean
for U.S. economic
activities to be
concentrated in just
a handful of metros?
“The Economy”, Cities, & ESDA
 GDP as a measure (the measure?) of economy
 GDP = gross domestic product
 Complicated calculation that alienates most non-
economists (Coyle 2014; Karabell 2014)
 Cities as concentration of knowledge/skills (Glaeser 2011;
Henderson 2000; Krugman 1995)
 Exploratory Spatial Data Analysis (Andrienko et al. 2001; Anselin
1994/5; etc.)
Data sources
 U.S. Census Bureau
 Core Based Statistical Areas, 2013
 Population, 2000 & 2010
 U.S. Bureau of Economic Analysis
 Gross Domestic Product by Metropolitan Area, 2001-2012

Included by industry or industry groups (but some suppression)
Potential features
 ESDA concepts
 Brushing, linking, highlighting, classification, etc.
 Graphs showing different trends
 Average metro GDP, % of U.S. total
 Simple animation over time
 GDP vs. population as animated through time
