UK Economy now in recovery phase
New rental and owning patterns
New immigration trends
Trends in urban/rural migration, household composition, family structures
Our Mosaic build team were charged with creating a segmentation for today and tomorrow, identifying the significant new trends we’ve seen in society…
Societal changes mean we need new clusters relevant to
understanding the UK consumer of today and tomorrow

Data from Rightmove and Government Open Data enables more accurate household level tenure data. We can confidently differentiate owners, private renters and social renters at household level.
Example – identifying consumers with different tenures living alongside one another in an estate that was once all social housing
2. New Data to Identify New Trends New Tenure data identifies significant changes in property ownership at household level

Census 2011 is a strong contextual data asset that accurately shows key demographic
characteristics of whole population. Gives valuable neighbourhood information such as
ethnic diversity, employment and industry, levels of education and health
28% of information used to build Mosaic UK is from Census. Experian produce ongoing
Current Year Estimates of key census variables which feed into the build

Singular Value Decomposition (SVD) is an advanced analytics technique to reduce “noise” in big data, making it easier to spot patterns.
Method used for analysing other huge data sets in our business - Hitwise and Cheetahmail.
Allows us to use all household and person information about a household, converting binary response data into “probability” scores
Scores have distributions, so better suited to clustering

New methodology clusters at household level using household & neighbourhood data to
exploit best clusters from both levels to drive optimum discrimination in all areas
3. Innovation in Methodology Optimising Mosaic at a household level
Household
clustering
using
smoothed
data
Postcode
allocation
Nearly 60% of households have a different
Mosaic Type to their postcode
Postcode DE75 7JA
Subgroups found even where they don’t group
together distinctly at postcode level
Household characteristics well defined across all age groups
Consumers in mixed neighbourhoods well defined by household characteristics
Neighbourhood characteristics still highly significant
Postcode allocation still retains optimum discrimination
Types dominated by locational factors such as rurality well defined

Improved identification of consumer types in rural locations
Consumers in rural locations can get grouped together because of location but in reality they
have very different incomes and lifestyles. Optimised use of household level data allows these
differences to be uncovered…..

Improved identification of emerging family types
3. Innovation in Methodology Optimising household characteristics
B08 Bank of Mum & Dad I37 Budget Generations
Families supporting adult children - Given financial pressures on young people from
high house prices/rents, student loans, finding employment..., more couples continuing to
provide a home for their children into adulthood
New types where adult children are living at home - Bank of Mum & Dad who can afford
to support their kids to Budget Generations where older children living at home more
likely to cause financial strain to parents. Cultural Comfort & Asian Heritage also have
high incidences of adult children living at home.

• Large urban areas very different to rest of UK and have seen big changes since last census
• Household level characteristics key in differentiating consumers in these locations - these differences can be lost at postcode level
• Use tried & tested methods
recently deployed in Tokyo - one of
world’s largest urban conurbations -
for Mosaic Japan
• Allows creation of more diverse
clusters, potentially new clusters and better discrimination

In inner London number of
types with >2,000 households
increased from 10 to 13
• Renters / Homeowners /
Council tenants clearly
differentiated
• Tiers of wealth, age,
household composition,
property type well
differentiated within renting
majority in these areas
• Household clustering
distinguishes much more
variation in old O63 Urban
Cool and O64 Bright Young
Things segments
3. Innovation in Methodology Example - we’re seeing significant improvements in discrimination in London
Main types old O63 & O64 are
allocated to in new Mosaic

For those who understand these things….!
Average distance to cluster/total error in
cluster
Relative sizes of clusters
Loss of variance of first join in dendogram
Variance explained in individual variables
Regional analysis
Characteristics of clusters make sense
4. Optimising Mosaic & Measuring Uplift Settling on a Solution: Selecting the best from the rest
In our segmentation process we
create hundreds of potential solutions.
We use a wide range of diagnostics to
test, select, validate and interpret
clusters created.
But a key “acid test” is that
characteristics of clusters
make sense and they’re
identifying key trends

4. Optimising Mosaic & Measuring Uplift Overall Performance improvement: 20% Uplift
Measure performance of Mosaic to
discriminate client customer bases
using
► Total Weighted Deviation -
how much client customer file
differs from UK in terms of it’s
Mosaic Distribution
► Lift Score – % of maximum
possible lift gained above
random assignment of types
Calculated these metrics across
>50 behaviour files covering many
different vertical markets.
On average seeing 20%
uplift in these metrics
compared to Mosaic 2009 By targeting 5% of our ConsumerView universe
you’d reach 21% of client’s customer base with
new Mosaic, but 16% in previous Mosaic

6. Other Useful Mosaic Data Sets Making the most of segmentation assets
Mosaic Segments - the DNA or basic building blocks of Mosaic. Can be combined on basis of specific data to create a bespoke segmentation to meet your needs
Mosaic Factors distil underlying data used to build each Mosaic, summarised into continuous non-correlated variables
“Distance” to Type measure extent to which household or postcode fits its allocated Type
2nd Best Type indicates which Mosaic Type is next best fit
Affinity Measures indicate how close a household or postcode is to ‘tipping point’ between Mosaic Types
Geographic aggregations of Mosaic mix to many geographical areas for use in location insight
Mosaic DNA!

Segmentation
Mosaic UK Segments are 238 subtypes split
out of 66 Types, providing further level of
discrimination for profiling & analysis
Build customised clusters with even more discriminatory power for clients – from
Mosaic DNA
Detailed household consumer
sub-types created using input
data from Mosaic.
Target organisations with niche
audiences not adequately
identified by Mosaic classification
Allows clients to capitalise on
input data used to build Mosaic &
build own bespoke
classification that can be linked
back to Mosaic
Our Mosaic Custom tool
developed to do exactly this!
