Its population pyramid
alludes to it with the higher percentage of males in all working age groups above the age of 20.

Forty years from now, in 2050, the population pyramid
(white) will look rather like a capped tower, with ample working-age cohorts as the birth rate remains low and the baby-boomer group gradually dies off.
have strong influence on age-sex structure of the population, that reflect also on the shape of the population pyramid
In terms of population change by age group, the population pyramids
clearly show large increases at all ages between 2001 and 2031.
39) Note that the use of the MY ratio as a summary statistic of the population pyramid
is justified only in the context of an intertemporal equilibrium of an economy with a cyclical birth rate: the MY ratio indicates where in the pyramid cycle the economy is located at a given time, but it does not imply that the young and the middle-aged cohorts that serve to define the ratio are the only cohorts whose trade influences the equilibrium--all cohorts trade, and all influence the equilibrium outcome.
The overwhelmingly young male profile of the plantation period gradually gave way to the more conventional population pyramid
as native-born Islanders came to outnumber the immigrants the exception being that men aged sixty-five and over, the survivors of the plantation period, formed the largest single age group cohort.
The golden age is when the population pyramid

back toward a low-harvest state with fewer pike but more large ones.
population, which numbered 152 million persons, was relatively young and its population pyramid
resembled a Christmas tree.
The population pyramid
for Series 4 (Figure 3) shows a drop in numbers at younger age groups by the year 2031, so that 'the numbers entering the young adult ages would shrink even more rapidly after 2030'.
