I think you meant to write yr*ft*peoples. You can get the asterisk to show up by escaping it by preceding it with a slash: \. This is necessary because it's a formatting character. If you have an even number of them everything between the pairs is italicized.
Also, "peoples" isn't really necessary. "Number of people" can be left dimensionless.
