What is the Data Deluge?
The internet
has 1800
exabytes of
data in 2011
exa = 10^18
50,000 exabytes by 2020
We live inexponential
times!
27 foldgrowth in the next9 years
Are these data interesting?
Probably 99.9% are videos, photos, audio files, text messages and other nonsense
But that still leaves
1,800,000,000,000,000,000
bytes of potentially relevant data
An Observation
More and more people post information about themselves on Facebook, but less and less complete statistical surveys
Should we create
STATVILLE?
Private sector competitors?
Google:• Real-time price indices• Public Data Explorer• First point of reference for the “data generation”
Facebook, store cards, credit agencies, ...• What if they link their data?
The private sector now understands the value of data:
Can they beat us at our own game?
High-Level Group for Strategic Directions in Business Architecture in Statistics
UNECE group, created by the Conference of European Statisticians in 2010
8 heads of national and international statistical organisations
Develop and promote new:
Sources Processes Products
Official Statistics Response
Endorsed by the Conference of European Statisticians on 14 June
We have to re-invent our products and processes and adapt to a changed
world
HLG-BAS Strategic Vision
The Challenges are too big for statistical organisations
to tackle on their own.
We need to work together
What does this mean in practice?
Collaboration
Coordination
Communication
Many international groups and projects are talking about streamlining and industrialising statistics
Industrialisation is:
Common processes Common tools Common methodologies Recognising that all statistics are
produced in a similar way:
No domain is “special” Increased flexibility to adapt to new
sources and produce new outputs
Changing roles in NSOs?
One source = one output Data integration – multiple sources Process quality assurance More focus on analysis and interpretation Partnerships for dissemination
Changing staff and cost profiles Changing organisational culture
Wider Definition of Admin Data?
New sources are “non-statistical” But - similar issues to “traditional”
administrative data sources
Whatever we call the new sources,we can’t ignore them!
Which new sources are you going to check
out?
