Improved sanitation is a term used to categorize types or levels of sanitation for monitoring purposes. The term was coined by the Joint Monitoring Program (JMP) for Water Supply and Sanitation of UNICEF and WHO in 2002 to help monitor the progress towards Goal Number 7 of the Millennium Development Goals (MDGs). The opposite of "improved water source" has been termed "unimproved water source" in the JMP definitions.

The same terms are used to monitor progress towards Sustainable Development Goal 6 (Target 6.2, Indicator 6.2.1) from 2015 onwards.[2] Here, they are a component of the definition for "safely managed sanitation service".

The Joint Monitoring Program (JMP) for Water Supply and Sanitation has been publishing updates on the global sanitation situation on an annual basis. For example, in 2015 it was reported that 68% percent of the world's population had access to improved sanitation.[3]

In 2015 this goal was superceeded by Sustainable Development Goal 6, in which Target 6.2 states: "By 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations." Indicator 6.2.1 is the Proportion of population using (a) safely managed sanitation services and (b) a hand-washing facility with soap and water.[4]


Definitions

During SDG period (2015 to 2030)

In 2017, JMP defined a new term: "basic sanitation service". This is defined as the use of improved sanitation facilities that are not shared with other households. A lower level of service is now called "limited sanitation service" which refers to use of improved sanitation facilities that are shared between two or more households. A higher level of service is called "safely managed sanitation". This is basic sanitation service where excreta are safely disposed of in situ or transported and treated offsite.[2]

The definition of improved sanitation facilities is: Those facilities designed to hygienically separate excreta from human contact.[2]:8

The ladder of sanitation services includes (from lowest to highest): open defecation, unimproved, limited, basic, safely managed.[2]:8

During MDG period (2000 to 2015)

Improved sanitation example: pit latrine with a slab covering the drop hole and handwashing station in Burundi

An improved sanitation facility is defined as one that hygienically separates human excreta from human contact.[5] It is not necessarily identical with sustainable sanitation. The opposite of "improved sanitation" has been termed "unimproved sanitation" in the JMP definitions.

To allow for international comparability of estimates for monitoring the Millennium Development Goals (MDGs), the Joint Monitoring Program (JMP) for Water Supply and Sanitation defines "improved" sanitation as the following kind of toilets:[5]

Unimproved sanitation example: pit latrine without slab in Lusaka, Zambia

Sanitation facilities that are not considered as "improved" (also called "unimproved") are:

Whilst "shared" toilets are not counted as improved sanitation, data about usage of shared toilets is nevertheless report in the annual progress reports of the JMP.[6]
