Spatial Analysis of Statistics
Overview
 Spatial Analysis of Statistics- Answering Where & How!
 Spatial Analysis Techniques- Processes & Methods
 Spatial Analysis of Census 2010 Results- Examples from
QSA Data Users
 Disseminating Spatially Analyzed Statistics- Printed,
Digital and through Web Applications

Spatial Analysis of Statistics -Answering
Where & How!
 Data Users are often not only interested in
answering the “How much” question, but
 “How much is Where” question
 Spatial (Geographic) Analysis of Statistics Transforms Data into Information, and
 Presents results to the users in a concise and easy to
understand manner
For ExamplePopulation Distribution representation through Maps

Spatial Analysis Techniques- Processes
& Methods
 Requires Geo-referencing & Coding of Data
Units Spatial Analysis of Census Data requires proper
Geo-referencing and Coding of Data Units for
collection and representation of Data.
 This is to be done at the time of Census
Operations and a Census Geography Database is
to be created, e.g., Qatar Census Geography

Spatial Analysis Techniques Processes &
Methods- Some Prevalent Forms useful with Population data
 Thematic Mapping- Spatial & Temporal
Common
 Choropleths- Color Maps
Advanced
 Dasymetric Mapping- using geographic layers such as Land use
 Volumetric Mapping- Estimating and Representing Statistics at
small Data Units level for which Census data is not made available-
e.g., for Buildings falling with in a Census Block
 Queries- Where & How and sometime answering Why!
 Transformation- Buffering- Point, Line & Polygon
14
Spatial Analysis Techniques Processes &
Methods- Some Prevalent Forms useful with Population data
 Contd..
 Spatial Interpolation- method designed to fill in values that lie between observations
(Samples).
The type of analysis include Kriging- estimate the values of unsampled sites Thiessen polygons- assumes that the values of the unsampled data are equivalent to
those of the sampled points.
 Centre of Population- used to display the center of population using the weighted
average of x and y coordinates of populated points
 Cluster analysis- regards the distribution of points in space irrespective of their actual
locations to determine whether patterns are random, clustered, or dispersed
 Hot Spots- are where high values are surrounded by high values, or cold spots, where low
values are surrounded by low values.
