Between 2013 and 2023, the population in Nigeria with access to improved drinking water sources showed a steady increase from 19 units in 2013 to 23 units in 2023. Despite some years of stagnation, there were notable increments in certain years, such as in 2015, 2017, and 2020, indicating periodic efforts and improvements in water access initiatives. The year-on-year variation highlights specific years of positive change, like 5.26% in 2015 and 4.55% in 2022, while other years demonstrated stability.
Longer-term trends reflect a Compound Annual Growth Rate (CAGR) of approximately 1.84% over the past five years, suggesting moderate but consistent growth in providing access to improved drinking water sources. Looking ahead from 2024 to 2028, projections indicate the population with access to improved drinking water sources will continue to rise, with an anticipated forecasted 5-year CAGR of 1.68%, resulting in an overall growth rate of 8.7%, reaching 25 units by 2028.
Future trends to watch for include government policies and investments in water infrastructure, demographic changes, urbanization rates, and the impact of climate change on water resources. Monitoring these factors will be crucial for sustaining and improving access to clean drinking water in Nigeria.
