This review, like the previous, does not evaluate the technicality or correctness of NBS data and accompanied Methodology. It essentially takes a look at the quality of NBS data releases, timeliness and punctuality, report reusability, release practices, report accessibility, public engagement, and adherence to provisions of The Statistics Act, 2007. The purpose of this review is to provide improvement feedback to the NBS so it can better serve Nigerians, Government and Businesses, as well as improve Nigeria’s ranking in the Open Data Inventory (ODIN) ranking which assesses the coverage and openness of national statistical systems.

2017 NBS DATA
RELEASES REVIEW

2. The Year 2017 was a remarkable year for the National Bureau of Statistics (NBS). It was the year
government delayed its appraisal because data were yet to be released by the NBS. Both the
public and the private sectors depended on the NBS to make business decision as well as
appraise Government’s performance
The institution sustained the tempo and did its best to meet the rising expectations of Nigerians.
No doubt, the year ended for the NBS with several laurels such as Public Service Excellence
Award (BusinessDay Newspapers), Special Institution of the Year (Finance Correspondents
Association), Public Sector Institution of the Year (Lagos Chamber of Commerce & Industry),
Public Sector Star Website Award (Nigeria Internet Registration Association), SERVICOM
Commendation, and the Federal Government’s National Productivity Order of Merit Award.
INTRODUCTION
The beauty in all of this is that Nigerians, Governments, Businesses, etc., can now rely on the
NBS to provide data which hitherto were sought outside Nigeria – this is a huge achievement.
Nevertheless, there is always room for improvement. Hence this review that was initially carried
out in 2017 on NBS Q1 2017 Data Releases. The analysis evaluated data published by the NBS
using The Statistics Act, 2007, the Guidelines for measuring statistical quality, UK and the Code of
Practice for Official Statistics, UK. The report can be found here: https://goo.gl/Z39Ysn.
This review, like the previous, does not evaluate the technicality or correctness of NBS data and
accompanied Methodology. It essentially takes a look at the quality of NBS data releases,
timeliness and punctuality, report reusability, release practices, report accessibility, public
engagement, and adherence to provisions of The Statistics Act, 2007. The purpose of this review
is to provide improvement feedback to the NBS so it can better serve Nigerians, Government and
Businesses, as well as improve Nigeria’s ranking in the Open Data Inventory (ODIN) ranking
which assesses the coverage and openness of national statistical systems.

3. REVIEW OF Q1 2017 REPORT & RECOMMENDATIONS
RECOMMENDATIONS:
 NBS should develop and disseminate its Code of
Practice and Data Release Policy.
 Governments (Federal & State) must demonstrate their
commitment to development by substantially improve
budgetary allocations to all Ministries, Departments and
Agencies (MDA) involved in data production for the
National Statistics Office.
 Equally, governments should increase the ability of the
Federal School of Statistics to focus more on the
production of Statisticians.
 Establish a quarterly electronic survey for User feedback
in terms of data relevance and future data needs.
 NBS should publish its reports in non-proprietary formats
that is reusable by users.

Timeliness: A December 2016 report is due for release in January 2017, therefore
the report is said to be timely. However, Q4 2016 report (Q4 2016 Foreign Trade in
Merchandise) being released in March 2017 cannot be said to be timely.
Punctuality: A report having been released 3 days before the scheduled date, can be
regarded as being punctual. While it is encouraging to publish report on time, a report
that is published ahead of scheduled timeline should be accompanied with a prior
information on the change of time.

20. ASSESSMENT – Accessibility and Clarity
Accompanying Metadata:
Metadata is a set of data that describes and gives information about other data. (Wikipedia)
Information such as Title, Summary, Overall design, Contributors, etc. give users better
understanding about the report. While Metadata are fairly available for most Reports and could
be extracted from the Methodology section of the report. Indicators need to be defined in Tables
for ease of reference and at the least all reports must contain a “Definition of Terms” section.
As listed in the table below, there are differences between Scheduled Title and Published Title;
this could easily confuse data users. Where titles of reports to be published are going to be
different from what was communicated in the Release Calendar, a proper Change Management
process must be followed to communicate these differences.

21. ASSESSMENT – Accessibility and Clarity
Report Accessibility to all:
All NBS reports are available and accessible on the NBS Website – www.nigerianstat.gov.ng.
With the number of Internet Users and Literacy rate in the country, majority may likely not be
able to access the reports – especially those in the rural areas.
Report Dissemination:
All NBS reports are available on their website and shared by the Statistician-General of the
Federation (SGF) through his handle – @sgyemikale. These reports are equally tweeted &
retweeted through the NBS official handle – @nigerianstat.
As already noted in our “Review of NBS Q1, 2017 Data Releases Report” in 2017, majority of
NBS reports and user engagements on the reports took place through the Statistician-General
handle while the official NBS handle often retweets. The downside of this is the ability of NBS to
continue to delight the public when the current SGF is no longer in office.

22. ASSESSMENT – Release practices
Statistical reports should be released into the public domain in an orderly manner that promotes
public confidence and gives equal access to all, subject to relevant Legislation. - Protocol 2:
Release practices, Code of Practice for Official Statistics, UK. Also, according the to Principle 15
“Timeliness and Punctuality” of the Code of Practice for Official Statistics in Nigeria; No. 3 “A date
and time is set for the dissemination of all official statistics. If the deadline is not going to be met,
notification must be given in advance together with the relevant explanation and an indication of a
new date for publication”.
NBS data releases for 2017 was governed by the Data Release Calendar, however there were
no set time or day of the week for releases. See below analysis showing days of the week when
reports were published in 2017.
Day of the Week Count %
Sunday 8 4
Monday 35 18
Tuesday 38 19
Wednesday 43 22
Thursday 23 12
Friday 25 13
Saturday 26 13
While report can be published any day of the
week and at any time of the day, it is important to
also publish reports when there is likely to be
maximum engagement.
From this table, Reports were published on
Saturday and Sunday. There is likelihood that
these data may not get the most engagement
they deserve as most people may not be online or
aware due to Religious activities on Sunday and
Sporting activities on Saturday.
As observed, the most downloaded reports were
uploaded on Tuesday (27,591), Wednesday
(19,515), and Monday (12,726).

INDICATOR RATING
Changes to published calendar should be communicated to the public for the purpose of
awareness and possible update to offline calendars. In addition, whenever it is impossible to
release reports as planned due to operational or data availability challenge, communicating with
the public on possible tentative dates will further strengthen public trust and engagement.
For maximum user engagement, it is therefore recommended that reports be shared mostly
during the week and at a preannounced time of the day, most especially between Tuesdays and
Thursdays.

1 Data Release Policy
According to The Statistics Act, 2007, Section 27, subsection (3):
“Each year, the Board will publish in advance the data to be
produced together with date, for the release of the data and all
data producing agencies including the Bureau will be required to
have a data release policy to be made publicly available and they
have power to impose charges for data products and services”.
While NBS currently publishes a yearly calendar of data to be
released, the agency should also publish all data producing
agencies. In addition, it should publish its data release policy.
2
Change in Release
Schedule
NBS should create and follow a change management process to
make changes to its published calendar, such that changes
(inclusion & exclusion of reports) made to the calendar are
communicated to the public.
3 Timeliness
Quarterly reports should be published the first month of the next
quarter. For instance, a Q1 report which covers January to March
should be published in April to meet the timeliness requirement.
4 Punctuality
As much as it depends on the NBS, it should ensure reports are
published as scheduled. In addition, while it is encouraging to
publish report on time, a report that is published ahead of
scheduled timeline should be accompanied with a prior information
on the change of time.

5
Ease of Report
reusability
While reports are currently published in Infographics, .PDF, and
.XLSX, NBS should strive to publish in other machine-readable
format (such as XLS, CSV, Stata, SAS, SPSS, JSON CDF, RDF,
XML, and TXT files).
This is one of the requirements of the Open Data Inventory (ODIN) “Openness Element 1:
Machine Readability”
6 Report Download Ratio
This indicator is used in place of “likeability” of reports. Two
additional features are recommended to better measure ‘Report
Likability’ – A “Like” button and a “web page hits” counter.

Metadata
Provide an inventory of definition of the indicators. It may be
included in the same file as the data or it can be included
elsewhere on the website.

Statistics to focus more on the production of Statisticians and fully
explore the provision in The Statistics Act, 2007which says: “award
professional and postgraduate diplomas in Statistics and related
courses in affiliation with an existing university;”
