Reference excerpt

This is a list of countries by access to improved sanitation facilities, which includes access to toilets and safe drinking water.

Methods Figures used in this chart are based on data compiled and uploaded by the World Bank in May 2013 through their World Development Indicators initiative. The information was provided by the respective governments of the listed countries. As the compiled figures are not collected with the same methodology and with different levels of rigor, there are limitations in their reliability in forming comparisons. Sanitation as defined by the World Health Organization:

"Sanitation generally refers to the provision of facilities and services for the safe disposal of human urine and feces. Inadequate sanitation is a major cause of disease world-wide and improving sanitation is known to have a significant beneficial impact on health both in households and across communities. The word 'sanitation' also refers to the maintenance of hygienic conditions, through services such as garbage collection and wastewater disposal. The United Nations states that improved sanitation facilities "ensure hygienic separation of human excreta from human contact." The Joint Monitoring Programme for Water Supply and Sanitation of WHO and UNICEF has defined improved sanitation as follows: flush toilet, connection to a piped sewer system, connection to a septic system, flush/pour-flush to a pit latrine, ventilated improved pit (VIP) latrine, pit latrine with slab, composting toilet and/or some special cases.

The World Bank states: "Access to improved sanitation facilities refers to the percentage of the population with at least adequate access to excreta disposal facilities that can effectively prevent human, animal, and insect contact with excreta. Improved facilities range from simple but protected pit latrines to flush toilets with a sewerage connection. To be effective, facilities must be correctly constructed and properly maintained."

Countries The following table shows the percentage of people using at least basic sanitation services, based on World Bank data.

Worked examples

Example 1 — a first encounter with List of countries by access to improved sanitation facilities

Start with the simplest possible case. Write down what List of countries by access to improved sanitation facilities claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of countries by access to improved sanitation facilities before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of countries by access to improved sanitation facilities ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of countries by access to improved sanitation facilities

In research: List of countries by access to improved sanitation facilities appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of countries by access to improved sanitation facilities in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of countries by access to improved sanitation facilities is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of countries, Lists of countries by population-related issue, Water supply and sanitation by country, so understanding it makes those chapters shorter.
In everyday life: Look for List of countries by access to improved sanitation facilities outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
