4. the number of women per thousand men...it is said.​

Answer 1

Answer:

Number of females per 1000 males in the population is called sex ratio.

The sex ratio is the ratio of males to females in a population. In most sexually reproducing species, the ratio tends to be 1:1. This tendency is explained by Fisher's principle. For various reasons, however, many species deviate from anything like an even sex ratio, either periodically or permanently.
