In a village, there are 20% more women than men. What percentage of the total population are women?

Let $M$ be the number of men in the village.
Let $W$ be the number of women in the village.

The problem states there are $20\%$ more women than men. This means the number of women is the number of men plus $20\%$ of the number of men.

The total population ($P$) is the sum of men and women.

Substitute the expression for $W$ from Step 2:

The percentage of women is the number of women divided by the total population, multiplied by $100\%$.

Substitute the expressions for $W$ and $P$ from Step 2 and Step 3:

The $M$ terms cancel out:

The percentage of women in the village is $\boxed{\text{54.55\%}}$.
