Rwanda Population Pyramid
I opted to look at Rwanda’s population pyramids in the years 1990, 1995, and 2000. In 1990, the population showed a symmetrical pyramid in which the population thins equally as it ages in all age brackets. It is the evidence that the population of both sexes is equal in all age groups. To draw examples, in that year alone, there were approximately 630,000 babies born of both sexes. Also, the children in the age bracket 5-9 numbered around 550,000 for both males and females (U.S. Census Bureau, 2012). I observed that in 1995, the new age bracket 0-4 numbered approximately 550,000 for both sexes. Similarly, I also found out that the now new age bracket 5-9 that was displaced by the new age bracket 0-4 numbered roughly the same. Without doubt, the 1994 Rwanda Genocide (it happened a year before this census) that claimed an estimated 800,000 lives was the reason that caused the sudden decrease of the population either through the killing of the children in those age groups perceived to be “enemies” of the warring tribes or pregnant mothers. This population pyramid aged thinly because all the others age groups numbered equally for both males and females as they aged except the 80+ age group whose male population slightly outnumbered that of females. Rwanda’s 2000 population pyramid differed from that of 1995. The new 0-4 age group was about 610,000 for both males and females. The 5-9 age group displaced by the 0-4 age group was slightly lesser than 500,000. However, 10-14 age groups, formerly 5-9 age groups, were around 450,000 for male population while their counterparts numbered slightly more than that. The rest of the age groups were equal in populations for both sexes and unlike the 80+ population in 1995, that of 2000 was balanced for both males and females.
