UNSD
10th Meeting of the Advisory Expert Group on National Accounts
13-15 April 2016, Paris * Prepared by Ronald Jansen, UNSD<br>
02
Drivers Availability of automatically generated data in electronic format, such as mobile phone, social media, electronic commercial transactions, sensor networks, smart meters, GPS tracking device, or satellite images
Higher frequency, more granularity, wider coverage, lower cost for data collection
Modernisation of statistical production and services 2<br>
03
Key messages Big Data for core national statistics – for integrated economic, social and environmental policies
Big Data for agile statistics – for emergency issues
Big Data to keep official statistics relevant – private sector moves fast
Big Data as part of modernization of statistical systems – new production processes and partnerships
Big Data to meet the data demand of the 2030 agenda – monitoring policies – “leave no one bend” 3<br>
04
Big Data for Official Statistics Benefits – Example of Social media data
Widespread use of social media, also in developing countries
Timely, high frequency and wide coverage
Great potential in tracking sentiments, such as consumer confidence
Potential use for tracking prices and outbreak of diseases, and useful in combination with other data, such as population census and geo-spatial data<br>
05
Examples of Big Data projects 5<br>

Examples 1: Telenor Big Data project on Poverty prediction (SDG 1) 6 Among the major mobile operators in the world Approaching 200 million mobile subscriptions
(e.g. in Bangladesh, India, Pakistan, Myanmar and Thailand)

15 Example 3:
Statistics Canada linking
Google Maps with the Statistical
Business Register (SDG 9)<br>
16
What can be gained from linking the SBR with Geo-spatial Information? Cross-sectional views of enterprise characteristics by (sub-national) regions:
Are there regional patterns of economic activity?
Are larger enterprises equally spread over the country?
Is FDI equally spread over the country? 16<br>
17
Statistics Canada– Geolocation of SBR data To study the potential of conducting economic analysis of small geographic areas by using Business Register (BR) microdata
Using BR data geocoded at the census subdivision (CSD) level, in combination with travel distance data generated from the Google Maps API
The identification of resource sectors is based on the aggregation of business data at the CSD level from the BR
A database was created, containing:
BR employment data, derived from payroll deduction files
BR revenue data, derived from the General Index of Financial Information, and
the six-digit North American Industrial Classification System (NAICS) code from the Business Register. 17<br>
