Populations are decreasing to Zeroes, unlike what Thanos says.
So assume we have Marriage rate at 28%, and we have 1 child per parents in average.(1/2). so we have 14%.. (marriage rate) (# of children per parents/2).. for every 25 years per generation:: (2+0.14);; 2.14/3 = 70% after 25 years;; 1.16/3 = 39% after 50 yeas;; 5.41% after 75 years;; (2+x)/3 & (1+x+x^2)/3 & (x+x^2+x^3)/3
So if more optimistic, marriage rate at 33%;; 1.5 children per parents. 1.5/2 = 0.75;;; (0.33)(0.75) = 25%;; 2.25/3= 75% after 25 years;; (1+0.25+0.0625)/3== 44% after 50 years;; 11% after 75 years. (2+x)/3 & (1+x+x^2)/3 & (x+x^2+x^3)/3
Send above math to Mathematicians or Researchers for Double Check.
The problem is that this Estimate is for Nations whose 1. Age 100 year to Age 200 year old 2. without Immigrants, 3. with some certain input values at marriage rate and child per parents.
與Thanos說的不同,人口正在減少到零。
因此,假設我們的婚姻率為28%,平均每個父母有1個孩子。(1/2)。 所以我們有14%..(結婚率)x(每個父母的子女數/ 2)..每一代每25年::(2 + 0.14);; 2.14 / 3 = 25年後70%;; 50年後,1.16 / 3 = 39%;; 75年後5.41%;; (2 + x)/ 3&(1 + x + x ^ 2)/ 3&(x + x ^ 2 + x ^ 3)/ 3
所以如果更樂觀,結婚率在33%; 每個父母1.5個孩子。 1.5 / 2 = 0.75 ;;; (0.33)(0.75)= 25%;; 25年後2.25 / 3 = 75%;; 50年後(1 + 0.25 + 0.0625)/ 3 == 44%;; 75年後11%。 (2 + x)/ 3&(1 + x + x ^ 2)/ 3&(x + x ^ 2 + x ^ 3)/ 3
將以上數學發送給數學家或研究人員進行檢查。
問題是,這個估計是針對那些年齡為100歲到200歲的國家2.沒有移民,3。有結婚率以及每個父母的孩子的輸入數值為特定 。
