Answer to Question 2

One measure of population composition is the sex ratiothe number of males for

every hundred females in a given population. A sex ratio of 100 indicates an equal

number of males and females in the population. If the number is greater than 100, there

are more males than females if it is less than 100, there are more females than males.

In the United States, the sex ratio for 2014 was 97, which means there were 97 males

per 100 females. Although approximately 124 males are conceived for every 100

females, male fetuses miscarry at a higher rate. At birth, there are 105 males for every

100 females, but because males at all ages generally have higher mortality rates than

females, the sex ratio declines with age. In the 2554 age category, the sex ratio in

2014 was 100, meaning that for every 100 men in that age category, there were 100

women. However, by ages 65 and older, the sex ratio was 77, meaning that for every

100 women ages 65 and older, there were only 77 men in this age category.
