ANALYSING SOCIAL MEDIA TO UNDERSTAND
PUBLIC PERCEPTIONS OF SANITATION
PARTNERS: UN MILLENNIUM CAMPAIGN & THE WATER SUPPLY
AND SANITATION COLLABORATIVE COUNCIL (WSSCC)
PROGRAMME AREA: PUBLIC HEALTH
BACKGROUND
The Water Supply and Sanitation Collaborative Council (WSSCC) is
a global organization committed to promoting sanitation, hygiene
and water access as a human right. WSSCC works with vulnerable
communities, governments and small-scale entrepreneurs to
improve sanitation and hygiene at scale. The UN Millennium
Campaign (UNMC) have worked with UN partners and key global
constituencies, such as civil society, parliamentarians, faith groups
and youth since 2002 to inspire people around the world to take
action for the achievement of the Millennium Development Goals.
In 2013, UNMC and WSSCC were asked to develop a
communications campaign to support the UN Deputy Secretary-
General’s Call to Action on Sanitation, aiming to break the silence
around open defecation and expand public engagement around
this issue to improve numbers of citizens with access to improved
sanitation.
In this context, UNMC and WSSCC wanted to understand the
baseline public engagement level, and to have a mechanism in
place to monitor and evaluate their advocacy and communication
efforts when the campaign launched.
UNMC and WSSCC partnered with Global Pulse to conduct a
baseline analysis of the global discourse on social media about
sanitation to understand general perceptions of sanitation to shape
the campaign, and for monitoring changes in public perceptions
during the campaign.
USING SOCIAL MEDIA DATA FOR INSIGHTS
ON PUBLIC PERCEPTIONS
In order to understand public perceptions on sanitation as
expressed on social media, Global Pulse filtered Twitter to extract
relevant conversations that could then be quantified.
A comprehensive list of keywords and phrases was developed in
collaboration with UNMC and WSSCC. Tweets containing a
combination of words from this taxonomy were most likely to be
relevant to the topic of sanitation (for example, the words ‘unclean’
or ‘contaminated’ in a tweet with ‘sewage’ or ‘pit toilet’). The
taxonomy was used to filter English language tweets about
sanitation posted from January 2011 to December 2013.
In order to measure the volume of tweets about different topics
related to sanitation, relevant tweets were then filtered into five
categories defined by UNMC and WSSCC:
1. Health (Cholera1
)
2. Human Rights
3. Gender
4. Policy and Governance
5. General Interest2
Social media data analysis was conducted using Crimson Hexagon
ForSight, a social data analytics platform. The following analyses
were performed on the extracted tweets:
• Overall trends: Measuring daily, monthly and yearly volumes
from January 2011 to December 2013
• Category trends and correlations: Analysing tweet volumes over
time, inferring causes of significant spikes (e.g. events,
campaigns and key influencers)
• Correlations: Identifying correlations between categories in order
to understand if topics are closely related in public
conversations, which could potentially improve and target
communication campaigns
1
Cholera was selected as a sub-category of ‘Health,’ which was necessary
because of the large quantity of tweets about cholera during the 2013
outbreaks in Mexico and Nigeria and continued social media discourse
about cholera in Haiti

This category contains all sanitation related tweets not included in the four
other categories.
SUMMARY
The United Nations Millennium Campaign and the Water Supply and Sanitation Collaborative Council partnered to deliver a
comprehensive advocacy and communication drive on sanitation. Their efforts were in support of the UN Deputy Secretary General’s
Call to Action on Sanitation to increase the number of people with access to better sanitation. Global Pulse provided an analysis of
social media in order to provide insight on the baseline of public engagement, and explore ways to monitor a new sanitation campaign.
Using a custom keyword taxonomy, English language tweets from January 2011 to December 2013 were extracted, sorted into
categories and analysed. The study showed that 33 percent of the relevant tweets focused on cholera. Excluding cholera-related
conversations, tweets were mainly in the context of human rights, followed by health and policy and governance. The analysis also
revealed increasing public engagement around gender and sanitation. By showing how the volume and content of public discourse
around sanitation changed over time, the study provided a baseline that could be used to monitor the effectiveness and reach of a
communications campaign in real-time using social media analytics.

• Influencers: Identifying the most influential Twitter accounts
posting tweets about sanitation (both accounts with a significant
number of followers and accounts mentioned most in tweets
about sanitation)
• Hashtags: Exploring which hashtags are used most frequently in
tweets about sanitation, the context within which hashtags are
used and how long different hashtags last in public Twitter
discourse
INSIGHTS & OUTCOMES
A total of 260,000 tweets related to sanitation from January 2011
to December 2013 were identified. 33 percent of tweets about
sanitation were related to cholera. The remaining categories—
Health, Human Rights, Policy and Governance and General
Interest—showed relatively low volumes of tweets in comparison.
The trend shows an increasing number of tweets written about sanitation.
Overall trends: For a preliminary analysis of tweet volume,
conversations related to cholera were excluded since the volume of
tweets was significantly more than the other four categories.
Results showed that people tweeted most about sanitation in the
context of Human Rights (57,817 tweets), followed by Health
(38,187 tweets), Policy and Governance (35,324 tweets), then
Gender (29,073 tweets) and General Interest (12,378 tweets).
Category trends: The time periods with highest volumes of
sanitation-related tweets coincided each year with World Water Day
on 22 March and World Toilet Day on 19 November. The most
significant increase in volume of tweets over time was found in
Human Rights followed by Gender and Health. Tweets about
sanitation in the context of Gender showed the largest proportional
increase in volume, compared to other categories, demonstrating a
greater percentage of public discourse focused on this issue.
The figures above show the proportions of tweets in each category over
time. The highest numerical increase in tweet volume was found in Human
Rights (grey), but proportionally Gender (blue) had the highest increase.
The analysis revealed the strongest positive relationship between
Gender and Policy and Governance with a correlation coefficient of
0.61, followed by Gender and Human Rights (0.584).
Influencers: The study revealed which Twitter accounts most often
tweeted about sanitation with significant numbers of followers.
These findings could be used in developing targeted messages and
maximize the reach of campaign communications by leveraging
influencers. These accounts included @unicef (2.46 million
followers), @un (2.27 million), @charitywater (1.41 million) and
@gatesfoundation (1.11 million). Accounts like @UberFacts and
@MindBlowing are another avenue of getting “facts” out to a
broader audience.
Hashtags: The hashtags #sanitation and #cholera were used most
frequently—over 19,000 tweets contained each—followed by
#water and #toilets4all. #Sanitation showed a clear upward trend,
while the use of #cholera was less predictable, indicating the
hashtag is event driven and is mainly used during actual cholera
outbreaks and in media discussions about past outbreaks.
The figure above compares the number of tweets that contain #cholera
(black) with #sanitation (blue) from 2011 to 2013.
CONCLUSIONS
This study set out to provide a baseline of public engagement on
Twitter relevant to the sanitation, around different categories. By
using these baseline indicators and categories it would be possible
to monitor how public conversations changed over time, and
evaluate campaign messaging reach and effectiveness. The study
provides a model for how to integrate social media analytics into
existing tools used to monitor campaign communications and
understand public engagement around an issue.
IMPLICATIONS & RECOMMENDATIONS
• This study demonstrated that social media could provide
useful insights about public perception and influence, and
how public discourse changes over time.
• It is recommended that the UNMC and WSSCC campaign
consider using both the general hashtag #sanitation as well
as a campaign-specific hashtag for broader reach.
• It is recommended that taxonomies be developed in
additional languages; this study could also analyse the
geographic regions from which tweets were posted, in order
to explore regional perceptions of sanitation.
