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
