Between 2013 and 2023, the total population in Indonesia using improved drinking water sources exhibited a steady year-on-year growth, varying around 0.21% for most years with a slight slowdown to 0.11% in certain periods. As of 2023, the urban population benefiting from improved drinking water sources stood at 95.3%. Over the past two years, the year-on-year variation was consistent at 0.11%. The Compound Annual Growth Rate (CAGR) over the last five years averaged 0.15%, illustrating a stable but modest increase in access.
Looking ahead from 2024 onwards, the forecasts indicate that this growth trend will persist, albeit at a slightly reduced CAGR of 0.1%, reaching 95.9% by 2028. The projected growth rate over the five-year period is estimated at 0.52%.
Future trends to watch for include government policies focused on expanding water infrastructure, urbanization dynamics, and the potential impacts of climate change on water resource availability which could all significantly influence progress in access to improved drinking water sources in Indonesia.
