Age structure of population human.The human population growth and reproduction, producing children for generations. The human population in each generation, it will further growth and reproductive you to give you over generations. According to the characteristics of the growth of the population Be divided by age range of human populations into 3 group is the pre-reproductive (per - reproductive) during the age from birth - 14 years. Puberty (reproductive) age from 15-44 years and Chondrus (post - reproductive) ages since 45 years. The population with different ages and. Age structure diagram (age structure diagram) which displayed in the pyramid. If the population in the pre-reproductive is large. Fertility rate would be higher mortality. Therefore, the pyramid structure of the population has a wide base of the spire, if the size of the group ประชากรใน reproductive age as the size of the population at the age of first reproduction. The pyramid age structure of the population, it will form a bell upside down. And if the size of the population in the pre-reproductive is smaller than the population in reproductive age. The pyramid age structure of the population will be lotus boom. The pyramid structure of population models. 22-15 shown in pictures.In the graph pyramid age structure of the population. The age difference in each of the 5 years. The population of male and female and split apart.
