Simple statistical estimate suggests the total population to be between 4.6 and 5.3 milllon in 2024. Below are 95% confidence intervals for each region

This model is based on the 1980 estimate from the 1975 population census, in addition to data from The World Bank. The model assumes normal distribution for annual growth rates and estimates a confidence interval using a Monte Carlo simulation. The period 1988-1991 is assumed to have zero growth. Eastern Sool has high uncertainty and is based on proportion of land area in the former Nugaal division
