“Dublin’s Place in the Irish and Global Economy, 2012”
Project Objective:
To examine Dublin’s place and role in the national and global economies through evidence based research and to deliver a research package of evidence to support investment in the Dublin city region.
Some policy questions to answer
• Where are the best locations nationally and regionally to ensure best return for investment of scare fiscal resources?
• What geographic areas are exhibiting clustering effects which may assist further and viable business formation and the growth of a knowledge economy?
• Where should future services such as in the areas of health, education and transport be located based on current patterns of development and opportunity?

Spatial Statistics
• Comprises a set of techniques for describing and modelling spatial data.
• In many ways extend what the mind and eyes do, intuitively, to assess spatial patterns, distributions, trends, processes and relationships.
• Unlike traditional (non-spatial) statistical techniques, spatial statistical techniques actually use space – area, length, proximity, orientation, or spatial relationships – directly in their mathematics.
Spatial Statistics toolbox in ArcGIS
• Includes both statistical functions and general purpose utilities.
• Helps to determine features’ geographic distribution, implement pattern analysis, mapping clusters and modelling spatial relationship.
• Core functionality (not an extension)
• Available at all license Levels
Mapping Clusters: Hot Spot Analysis
Identify where spatial clustering occurs, and where spatial outliers are located:
– Where are the sharp boundaries between affluence and poverty?
– Where do we find anomalous spending patterns?
– Where do we see unexpectedly high rates of diabetes?
– Where the most jobs are concentrated?
– Where do we see significantly high rates of unemployment?

Opportunity Mapping
• Opportunity mapping is an approach to conceptualise and visualize the varying levels of access to the opportunities which exist throughout different places and regions.
• Having high access to opportunity means having the ability to obtain a quality education, being able to have a safe place to live, having employment options, having access to transport network, health services, and more.

Opportunity Index
• The indicators were analysed relative to the other EDs within the country by standardizing through the use of z-scores.
• A z-score is a statistical measure that quantifies the distance (measured in standard deviations) a data point is from the mean of a data set:
