Talk:Population pyramid

message: this population pyramid also show what kind of country it is if the country
is shaped like a pyramid itself then this country is a developing country since the number of babies that will grow will decrease. the decrease of the number of of babies also shows that the medical care is not good and as you go up to the working age the number of them are insufficient for the country to grow, this means that the country will grow very slowly or not grow at all. 
now for developed countries the graph will look like a oval. low birth rate and low death rate. this will give more working age people. so the country will faster, but the number of old people is high. which means that the government will have to pay a big amount of pension. — Preceding unsigned comment added by 89.148.29.238 (talk) 06:55, 30 September 2006 (UTC)
thread_title:  Analysis 

message: "Heinsohn claims that -- most genocides can be readily explained as a result of a built up youth bulge, including European colonialism, 20th century Fascism, and ongoing conflicts such as that in Darfur and terrorism."
So is colonialism equal to genocide? Did Mussolini kill that much people? I don't know about Darfur, but isn't it a bit too bold to claim terrorism being caused by youth pulge? Even if Heinsohn really said this why should we give a wrong impression by citing him?

thread_title:  Genocides? 

message: Wouldn't it be interesting to also put the names of the age groups, e.g. youth = up to the age of 25 according to the UN, and then babies, kids, youth, young adults, adults, active retired, elderly, or so ?--OLPC - Sven AERTS (talk) 22:15, 29 March 2009 (UTC)
thread_title:  Age group 

message: This section needs some sources, and to shed the original research. It should also be balanced with a summary from Baby boom, which is a mainstream term for the expansion phase. Note that the "youth bulge" leads to what is called a "demographic dividend":, so this should be mentioned too. It also equates to stage 2 of the demographic transition model.

thread_title:  Youth bulge 

message: Not being an adept in statistics, I cannot help much to improve by contributing information here.
BUT as a user, I would appreciate if someone defined how "MEDIAN AGE" is calculated before going on to use the term freely in articles about Ageing and Population Growth etc. (where I found the term).

thread_title:  Request for a diagram 

message: What would a population pyramid for ZPG look like? Seems to me it should approximate a Gaussian distribution with low birth rates matching death rates at the high end and a bulge in the middle at the average age. Population pyramids are a statistical description of age distribution in a particular population. Any inference of human behavior from them is nonsense. Virgil H.

message: I would suggest adding some more examples of population pyramids in different stages of the demographic transition model. You can also talk about the replacement level or dependency ratios.
