OnTheMap for Emergency Management – Uses
Assessing Workforce Impacts
Identify the number and location of affected workers
Examine workforce demographics
Identify affected Industries
Visualize where affected workers live
Assessing Population & Housing Impacts
Identify the number and location of affected residents
Examine population demographics of affected areas
Identify vulnerable population groups
Examine housing characteristics of affected areas
Emergency Preparedness & Response Planning
Where should response efforts concentrate?
 Are there special or vulnerable population segments?
 Uncover surrounding communities with secondary affects to workforce

ACS Data Basics
 Retrieve characteristics about an area
 Measure socioeconomic change
 Based on a small sample of households each
month
 Replace detailed information from decennial
long form (income, education, employment
status, disability, etc.)
27
ACS Geography
 Larger geographies - think county vs block,
more people (in theory), more samples, lower
margin of error (MOE)
 Smaller geographies typically have larger
MOEs
 Small events interact with small geographies
28
EM Geography
 For LODES or Decennial datasets, all blocks in
an area can be aggregated because there is no
MOE
 ACS data can be more complicated because
better estimates come from larger areas
 EM aggregates these together automatically
29
Checking Geography and Data
 Use OnTheMap (onthemap.ces.census.gov) to
examine the underlying geography of an event
 Understanding what’s happening allows for
better use of the data
