Generation Alpha & Beta
in Republic of the Congo
How many of each cohort Republic of the Congo has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Republic of the Congo has approximately 2.7 million Generation Alpha people (born 2010–2024), about 40.9% of its population, and roughly 349,112 Generation Beta children born since 2025. Its fertility rate is 4 and its child population is growing, projected +23% by 2040.
