Proportion of Households with Access to Adequate Sanitation in 2021

Based on the results of the National Socioeconomic Survey (Susenas) by the Central Statistics Agency (BPS), 80.29% of Indonesian households had access to adequate sanitation in 2021.

Households with access to adequate sanitation are defined by the following criteria:

* Toilets with an S-bend trap;
* Final disposal of feces using a septic tank or wastewater treatment plant (IPAL/SPAL);
* The facility is used by the household itself, together with certain other households, or in a communal toilet.

The province with the highest percentage of households with access to adequate sanitation is Yogyakarta Special Region, at 97.12%, followed by Bali at 95.95%, and DKI Jakarta at 95.17%.

Provinces with the lowest percentage of households with access to adequate sanitation are Papua, at only 40.81%, followed by West Sumatra at 68.68%, and West Java at 71.66%.

By region, only 75.95% of rural households had access to adequate sanitation in 2021. This figure is lower than that of urban households, which had 83.58% access to adequate sanitation.

For rural areas, households are categorized as having adequate sanitation if the toilet uses an S-bend trap, and the final disposal of feces is to a septic tank or pit latrine.
