Here we have a population profile, this is of Ireland in 1971. Population profile are suppose to shows population in the number of age. In this profile it expresses the ages from 0 - 100 of males and females. Some profiles like this one shows a key about which age is the median which was 28, the total number of the both males (10234) and female (10326) , as well as the ratio of females to males that is 1.01. As you seen in this profile it says the years (1971-2043)in which it took it sample from but in fact this is only the 1971 profile because at the bottom of the profile it has a back to forward slide bar and it is on all the back to represent 1971.
