Following the Government’s endorsement of the National Statistician’s recommendation on ‘the census and future provision of population statistics in England and Wales’, the ONS Beyond 2011 Programme has been closed and replaced by the new Census Transformation Programme. The new programme is focusing on developing the strategies and plans needed for delivery of the following major strands of work:- 1. An online census in 2021; 2. Integrated statistical outputs that make use of administrative data and surveys in conjunction with the census; 3. A recommendation for the future provision of population statistics beyond 2021. This presentation will outline ONS plans for Strands 1 and 2: to deliver a predominantly digital census while making the most effective use of administrative and survey data in its design, operation and outputs. It will cover the challenges of providing a census in 2021 that is 'digital by default', while building on the successes and lessons from the 2011 Census. Main areas that will be outlined include plans to address the challenge of digital exclusion while maximising the benefits of electronic data collection such as data quality, real-time response information and reducing processing time. Strand 2 is new for 2021, and looks at enhancing the traditional census building on the understanding of the opportunities and limitations of administrative data gained in Strand 3. Challenges include considering the most effective use of administrative and survey data in: optimising census data collection operations, estimating missing data, quality assuring results, reducing respondent burden or expanding topics covered.

Strand 3 continues with research carried out in the Beyond 2011 Programme exploring the potential of administrative data and surveys as a future alternative to traditional Census taking beyond 2021. Building upon the concept of ‘Statistical Population Datasets’ derived through anonymous linkage of multiple administrative sources, the ONS plans to release a series of annual ‘trial output’ statistics to deliver early benefits and engage users with the development and evaluation of methods. ‘Trial outputs’ are intended to illustrate what might be realised from administrative data, in particular the range and frequency of outputs, and the potential for small area statistics. The first release will focus on local authority population counts at age/sex level. Subsequent annual releases will aspire to produce smaller area population counts and additional outputs on households, income and ethnicity, subject to data access and quality. This presentation will outline ONS plans to deliver trial outputs in the run up to the 2021 Census.

Strand 3 is continuing with research carried out in the Beyond 2011 Programme to develop an evaluation framework for assessing the suitability of using administrative data in the context of population statistics. By linking individual records between administrative sources and to Census data, a more informative view of data quality can be formed with particular focus on the statistical outputs being targeted. This presentation will highlight with examples the strengths and weaknesses of using administrative data to produce statistics about the population and its characteristics. Our results focus on the interpretation of cross-source and longitudinal linkage to demonstrate the extent to which the locational accuracy of administrative data can be relied upon to record individuals at their current place of residence. In addition, we present some of the challenges of producing statistics from differing statistical definitions, for example households and ethnicity, as well as variability in operational processes underpinning the collection and maintenance of administrative data.

The Outlook for Data 2017: A Snapshot Into the Evolving Role of Audience InsightFilipp Paster
Data is playing an increasingly critical role across a vast range of advertising and marketing applications. Marketers, media buyers, publishers, and digital advertising technology executives said that a renewed focus on measurement and attribution will be the centerpiece of their efforts in 2017 —a shift from 2016, when “cross-device audience recognition” took the lead position. This second annual benchmarking report explores how digital marketing and media practitioners are using audience data, and how they intend to evolve their data-centric practices in the year ahead.
This lecture will analyze the increasingly important topic of assessment and evaluation in e-government. Different models, methodologies and approaches will be presented.

What is Data Governance and why it’s crucial for PropTechPrecisely
Customer, client, supplier, internal, private, third-party data…
The amount of data available to real estate companies is truly outstanding! With the push of digitization and the changes Covid demands of real estate, businesses want to put high-quality data into the hands of the people who use it to do their jobs.
That means organizations must build processes that define who owns what data, how it can be used, how to maintain it meaningful to their business, and how to make it consumable by everybody in the organization, not just the data experts.
Data governance is no longer a choice in this data-filled, fast-moving space.
Join us to learn about:
What is Data GovernanceHow to manage, improve and control the quality of the dataHow to empower a common understanding of data through your organization
How to Build Data Governance Programs That Lasts: A Business-First ApproachPrecisely
Data analytics and Artificial Intelligence play an increasingly pivotal role in most modern organizations. To keep those initiatives on track, enterprises must roll out data governance programs to ensure optimal business value. Data governance has become a fundamental element of success, a key to establishing the component of the data integrity framework in any business. The most successful data governance programs use a business-first approach, delivering quick wins and cultivating sustained success throughout the organization. Unfortunately, many organizations neglect to implement such programs until they experience a negative event that highlights the absence of good data governance. That could be a data breach, a breakdown in data quality, or a compliance action that highlights the lack of effective controls. Once that happens, there are several different paths a data governance initiative might take. A typical scenario often plays out this way: The executive team calls for implementation of a company-wide data governance program. The newly-minted data governance team forges ahead, engaging business users throughout the organization and expecting that everyone will be aligned around a common purpose.
Data Governance: Business First, Govern AlwayPrecisely
Data Governance requires a strong foundation and commitment to make it work, from understanding a business’ needs first before implementing a future proof governance policy. In this presentation for the CDO/CIO Sit-Down series, Melvin Cheong explores the key components that are necessary to build a sustainable program and a fully functional data integrity framework for long-term engagement within your organisation.
Netta Hollings (Programme Manager - Mental Health and Community Care) discusses how you can get the most out of the Maternity Services Data Set (MSDS) and the Child Health Data Sets.

Survival Guide: Taming the Data Quality BeastTechWell
As companies scramble to adjust to the demands of an increasingly data-driven world, testers are told “go test data quality” without any guidance as to what that entails or how to go about it. The fact that the data is often a living, flowing ecosystem, rather than just a single object, requires the use of different strategies to gain meaningful insights. Shauna Ayers and Catherine Cruz Agosto guide you through the challenges of data quality and apply a structured approach to analyze, measure, test, and monitor living data sets, and gauge the business impact of data quality issues. Shauna and Catherine define data quality, describe the five goals of data quality management, provide the four pillars of data quality assurance, and show how data flow, scale, and properties interact to build the data quality landscape. Learn how to tame the data quality beast, determine what and how to test, overcome technical obstacles—and emerge with a usable plan of attack.
Leveraging Data in Financial Services to Meet Regulatory Requirements and Cre...Perficient, Inc.
Regulators have increased their scrutiny on the financial services industry in recent years and have levied fines against banks of all sizes – fines that have reached into the billions of dollars.
Because of this, the financial services industry is focusing considerable time and expense on capturing data to meet regulatory requirements in reporting, risk management, and compliance. Gathering, enhancing, and reporting the required data from multiple applications to meet regulatory demands is a significant challenge, and firms often address these data challenges as one-off projects with the objective of complying with a single regulation rather than improving risk management overall. Mergers and acquisitions further complicate these efforts by increasing the number of systems that information needs to be pulled from.
Meanwhile, revenue-generating exercises that could benefit from the availability of better client and market information often go unfunded due to an over-arching focus on regulatory compliance.
Rather than structure your data project as a tactical approach to meet regulatory requirements, learn how your data investment can drive true cost savings, fine avoidance, revenue creation, and competitive advantage.
This event promises:
• An experienced point of view on current regulatory, compliance and anti-money laundering issues that financial institutions are facing.
• Pros and cons of tactical versus strategic approaches to meeting regulatory requirements, specifically around data governance,
• Examples of how you can leverage data governance to drive compliance as well as competitive advantage.
This presentation covers the key question: Why dashboards? Local authorities and other public bodies have largely ended publishing reports and now produce dashboards. What are the factors that have contributed to this change?
This is the first presentation from our Workshop on 21 September 2023 on Dashboards, APIs and PowerBI.
ONS Local has been established by the Office for National Statistics (ONS) to support evidence-based decision-making at the local level. We aim to host insightful events that connect our users with exciting developments happening in subnational statistics and analysis at the ONS and across other organisations.
In April 2022, as the impact of increases in the Cost of Living really came to the forefront, Public Health & Communities, Suffolk County Council published a Cost of Living profile as part of the Joint Strategic Needs Assessment.
Alongside a written Cost of Living report ‘Making ends meet: The cost of living in Suffolk’, an interactive dashboard was also created using Power BI. In addition to internal data flows, publicly available data from sources such as the ONS have been used to provide a rich picture of the current situation for the local community.
The dashboard was developed in order to:
• Provide up to date data and information on the Cost of Living for Suffolk County Council, partner organisations, and members of the public.
• Deliver an interactive tool to allow users to focus on areas most relevant to them.
• Demonstrate that, while increases in the cost of living affect everyone, impact will be greatest for those who are already under financial pressure, exacerbating inequalities.
• Provide a source of actionable insight to support the system with the evidence base needed to support project development, drive change and really make a difference in the community.
Features of the dashboard:
• Place-focused - published at smaller geographies where possible
• Collaborative - Includes local data from across the system such as data shared by Citizens Advice and other system partners.
• Automated - Most data sources have automated connections, meaning there is little manual intervention required.
• Self-Service - Making the report publicly available puts data at the fingertips of colleagues, system partners and members of the public.
• Live - The dashboard is a living report which is frequently updated.
This session will:
• Provide a demonstration of Suffolk County Council’s Cost of Living dashboard
• Give an overview of data sources
• Explore opportunities for automation using Power BI
• Discuss how the data dashboard is used locally
This event is open to all; however, we anticipate it will be of most interest to anyone working on cost of living dashboards at the local level.

From 1 August 2019, the Secretary of State for Education delegated responsibility for the commissioning, delivery and management of London’s Adult Education Budget (AEB) to the Mayor of London. The AEB helps Londoners to get the skills they need to progress both in life and work. The overarching aim of London’s AEB is to make adult education in London even more accessible, impactful and locally relevant.
In this presentation, the Greater London Authority will be going through the results of the pioneering 2021/22 London Learner Survey (LLS). The survey’s objective is to gain insight into the outcomes of learners to inform and improve policy. The LLS consists of two linked surveys of learners who participated in GLA-funded Adult Education Budget (AEB) learning in the academic year 2021/22.
In the LLS, Learners are surveyed prior to and 5-7 months after completing their course to estimate the economic and social changes that learners experience following an AEB course.
In particular, the presentation will show the economic impact broken down by:
. Progression into employment
. Progression within work
. Progression into further learning.
The social impact will be explored by looking at changes in:
. Health and wellbeing
. Improved self-efficacy
. Improved social integration
. Participation in volunteering
The presentation will also cover how outcomes vary by funding type, breaking down the results by Community Learning and Adult Skills.
This event is open to all; however, we anticipate it will be of most interest to anyone working at a local level on skills, education and employment.
If you have any questions, please contact ons.local@ons.gov.uk.
The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.
ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

• History and the need for a framework
• The toolkit
Risk/Profile matrix
4 practice areas associated with data quality
• Using the framework across ONS and GSS
UK Trade
Population statistics
Census and QAAD
• Development of helpful tools and documents
4. Benefits of the toolkit
Adaptable, Pragmatic, Proportionate
A tool to understand and improve quality
A basis for a shared understanding
6. Context of Admin Data
• Admin data used for statistics for over 150 years
in the UK
• New technology enabling greater use of admin
data
• General assumptions:
‘admin data can be
relied upon with little
challenge’
‘unlike survey data,
admin data are not subject
to any uncertainties’
7. Meeting the regulatory standard
National Statistics status
means that official statistics
meet the highest standards of
• trustworthiness
• quality
• public value
Code of Practice for Official Statistics
8. History:
Police Recorded Crime Statistics
In January 2014 the independent UK Statistics
Authority removed the “National Statistics”
designation from Police Recorded Crime Statistics
• Concern over quality of
underlying data
• Concern over compliance with
recording standards
• Lack of information on quality
9. Admin Data Quality Toolkit
• UK Statistics Authority Developed
Administrative Data Quality Assurance Toolkit
• Enable benefits of administrative data
• And recognise that statistics derived from
administrative data are subject to:
• a range of potential biases
• incompleteness
• errors
10. Essential questions
• How do you know the data are
sufficiently reliable and suitable
to be used to produce official
statistics?
• What do users need to know
about their quality to use them
appropriately?
11. Quality Assurance Toolkit
• Assessing the
assurance level
• Providing evidence
to support rationale
• Collating evidence
of the actions taken
to comply
• Presenting evidence
of embedded
practices for
keeping QA
arrangements under
review
12. Level of risk of quality concerns /
public interest profile
Pragmatic and proportionate
1. Consider the likelihood of quality issues arising in
the data that may affect the quality of the statistics
2. Consider the nature of the public interest served
by the statistics
3. Judgment about the suitability of the administrative
data for use in producing official statistics should be
pragmatic and proportionate

14. Levels of assurance
14
A1: Basic assurance
Statistical producer has reviewed and published a
summary of the administrative data QA arrangements
A2: Enhanced assurance
Statistical producer has evaluated the administrative data
QA arrangements and published a fuller description of the
assurance
A3: Comprehensive assurance
Statistical producer has investigated the administrative
data QA arrangements, identified the results of
independent audit, and published detailed documentation
about the assurance and audit
16. Four practice areas associated
with data quality
Operational context &
admin data collection
Communication with
data supply partners
QA principles,
standards and checks
by data suppliers
Producers' QA
investigations &
documentation
17. • environment and processes for
compiling the administrative data
• factors which affect data quality and
cause bias
• safeguards which minimise the risks
• role of performance measurements
and targets; potential for distortive
effects
Operational context & admin data collection
18. Communication with data supply partners
• build relationships with:
- data collectors
- suppliers
- IT specialists
- policy and operational
colleagues
• formal agreements detailing
arrangements
• regular engagement with
collectors, suppliers and users
19. QA principles, standards and checks
by data suppliers
• data assurance arrangements in
data collection and supply
• quality information about the data
from suppliers
• role of operational inspection and
internal/external audit in data
assurance process
20. Producers' QA investigations & documentation
• QA checks carried out by
statistics producer
• quality indicators for input data
and output statistics
• strengths and limitations of the
data in relation to use
• explanation for users about the
data quality and impact on the
statistics
21. Quality management actions:
Investigate: Manage: Communicate
Communicate
Manage
Investigate
Investigate – such as:
Data suppliers’ own QA arrangements
Results of external audit of the admin
data
Areas of uncertainty and bias
Distortive effects of targets and
performance management regimes
Communicate – such as:
Description of data collection process
Regular dialogue with suppliers and providers
Document quality guidelines for each set of statistics
Description of errors and biases and their effects on the statistics
Communicate with users
Manage – such as:
Cooperative relationship
with suppliers, IT and
operational, and policy
officials
Guidance information on
data requirements
QA checks and
corroboration against
other sources
24. UK Trade Background
• Data are supplied from over 30
feeder sources, including a
variety of administrative data
sources, the main one being
HM Revenue and Customs
(HMRC).
• UK Trade statistics compiled by
ONS has been one of the countries
key economic indicators
• Aim : reinstatement of official
statistics badge and improvement
of the quality assurance reporting
25. • Introduction of the QAAD
workshop
• Mapping data sources
• Determining risk to quality and
public interest
• Data suppliers information day
• Video conference meetings
• Presenting quality information
to users
UK Trade work on QAAD
26. Development of helpful tools and
documents
• Literature review
• Risk/Profile Matrix Template
• Admin data Supplier Questionnaire template
• Guidance to apply QAAD
• QAAD – FAQs for Statistical Producers
• QAAD Questions - what do I need to ask
• QAAD – Case examples
27. Admin data sources -
Data Supplier Questionnaire
Data Supplier Questionnaire Template
This questionnaire is part of an ongoing assessment of ... (insert output).
It is a part of a requirement set by United Kingdom Statistics Authority to assess the quality
assurance of the administrative data being provided and published as Official Statistical by the
Office for National Statistics.

29. Results so far – UK Trade
• List all admin data sources and apply the toolkit to
them
• Get better understanding of their admin data
sources
• Improve communication with data suppliers
• Produce detailed process map
• All Standard Level Agreements (SLAs) have been
re-visited
• Actions in place to address difficult to reach data
suppliers
• Final report is being finalised for UKSA
assessment
30. QAAD use in Population Statistics
• Work began in late 2015 to support
Population Statistics bid for National
Statistics accreditation on key
releases
• Established admin data use across
Population Statistics
• Surprisingly large: Population
Estimates alone have 19 sources
• Lots of re-use of admin data within
Population Statistics
31. QAAD use in Population Statistics –
next steps
• Programme of work agreed with
UK Statistics Authority (to be
completed in 2016)
• Risk-Profile scores and assurance
level for a source vary within
Population Statistics depending
on use in statistical estimation
process
• Highest assurance level used as
Population Statistics assurance
level, not the highest risk score
and the highest profile score
32. QAAD use in Population Statistics -
challenges
• Admin data sources not always straight
forward
• Included in peer review of all reports are:
UK Statistics Authority
Producers
Suppliers
Welsh Government
NISRA
National Records of Scotland
33. QAAD and Admin Data Census
• Data sources for Census
being used for research
• Working to put QAAD in
place
• Ready for Official
Statistics publication
Preparing for the start
34. Benefits of the toolkit
Adaptable, Pragmatic, Proportionate
A tool to understand and improve quality
A basis for a shared understanding
37. Impact and goals
Shorter term: Better understanding,
knowledge sharing, evidence for Admin
Data Toolkit – communicating quality
Longer term: Methodological
improvement, improvements in accuracy
38. How Census is working with Admin Data Suppliers

49. Data Quality
• “Datasets” vs. “databases”
• ‘Data quality’ means different things:
– Completeness, timeliness, conformance
– Recording what’s needed for the workflow
• Mixing the two can lead to unintended
consequences
• ‘Errors’ aren’t always obvious …
• … and neither are the causes
50. Consequences of success
• ‘Use the NHS Number’
• Staff (and systems) know this and act on it
• Many can now ‘allocate’ NHS Numbers
• But imperative can lead to poor practice:
– The 200-year old patients
– “Unknown Eritrean”
– Duplicate/multiple records for same patient

52. Local vs. National
• Much local EPR-PDS interaction is seamless:
– So the data is largely kept consistent
– But user awareness of local/national not always clear
– And local practices can have an impact
• Hence the rare but real examples of discrepancies:
– “Baby”
– Walking the dog/Bridge on Thursday afternoons
– Key safe codes
– ‘Ping-pong’
• From user perspective makes sense …
• … even if it’s obviously ‘wrong’ usage
54. The odd and the mundane
• From woman in Wales to man in Bradford
• I thought he was dead
• We don’t always know where you live:
– Different address types
– ZZZ addresses
– ‘SAME’ address
– The mailman always delivers (so don’t worry
about the postcode)
55. Final thoughts
• ‘Aggregate data from operational data’ isn’t as simple as
it sounds
• Care about assumptions re national databases:
– Users aren’t consciously ‘collecting data’
– Context, provenance and operational use all need to be
understood
– For NHS: tens of thousands of users, thousands of
organisations, dozens of service/business uses
• Conversely, caution about adding data items (and never
ask about “a flag on PDS”)
• On scale of national surveys, unlikely to have massive
impact
• But linkage of datasets may be affected
58. Questions
• What challenges have you faced with using admin data (in local
authorities etc)?
• What are your main concerns about the statistical quality of admin
data?
• What trade-offs on quality do you make?
• What trade-offs on quality would you be willing to accept
• How can we best / what other ways can we collaborate and engage
with suppliers of admin data?
• As suppliers, what challenges might you face with providing the type
of information the toolkit requires? How best can we work with you
to help identify/understand these?
Editor's Notes
Points to note:
Detail/busyness
PDS compliance specification ‘Jargon’ vs. BAU terminology – “patient telecom” “usage” “method” “string”
Process options – too many to choose
