How many girls have turner syndrome?
I can't speak for the U.S. specifically but according to the National Institutes of Health, Turner Syndrome effects 1 out of every 2,500 female live births worldwide. For more information about it, you can peruse NIH's site at:http://turners.nichd.nih.gov The site has a wide variety of publications you can access, information about current studies, and even the contact information for a NIH doctor if you have questions about the syndrome.
Is number of birth a ratio scale measurement?
Birth by itself would not be a ratio scale measurement. It would merely be a count. To have a ratio, an item must be in relation to another item. Here are some examples as statements:(General count statistic: A hospital oversaw 300 births in a 1-year period.)(Ratio: Of 15,000 women in a community, 300 babies were born during a 1-year period.)(Ratio: From 2,079 patients admitted to the hospital in that year, 300 were women in labor.)Of the 300 births, half were born to Caucasian women, and half to Black women of Jamaican descent.Of the 300 births, 245 babies and mothers had no birth problems.Of the 300 births, 10 babies were born breech.Of the 300 births, 45 were delivered by C-section.Of the 300 births, 102 showed signs of maternal drug use.Of the 300 births, 12 babies had an Apgar of 3 at 1 minute which improved to 5 at 2 minutes.Of the 300 births, 112 babies experienced very mild jaundice within 12 hours.Of the 300 births, 2 babies developed serious jaundice within 12 hours.Each of these could be written as (x number): 300, example 102:300. The colon would mean out of or from this number.If you only present the "counts" without the total stated, that's just counting, not a ratio. For example:300 babies were born. That gives no ratio information. It's just a count.

Percentage of people that are affected by downsyndrome?
* Down syndrome, caused by trisomy of the 21st chromosome, overall is seen in about 1 in 750 live births. The incidence, however, increases dramatically with increasing maternal age. If you look at the link below, under about age 30, there is a 1:1000 chance in having a child with Down syndrome, however, at age 40, there is about a 1:100 chance. This increases to 1:10 by age 50. 80% of all children with Down syndrome are born to women under the age of 30, however, because women of this age group have children at a much higher rate than those over 30. * Approximately 1 in 800-1,000 babies are born with Down syndrome. * The overall incidence of Down's syndrome is 1 in 660 newborns, thereby making it the most common pattern of malformation in man. === === * According to scientific data, Down syndrome occurs in 1 out of every 750 births.
