What was the ratio of men to women in the 1990s?

In which era, although boys were preferred to girls, the sex ratio of the population was not as large as it is now, about 6 men and 4 women. Now there are 30 million men who have money to spare, so it is difficult to get married and find the right woman. Of course, there are many elderly women in this city. Why? Because women are too picky, men can't find them, and neither can women. The single world has begun. .
