Twenty to forty percent over ideal weight is considered mildly obese; 40-100% over ideal weight is considered moderately obese; and 100% over ideal weight is considered severely, or morbidly, obese.

More recent guidelines for obesity use a measurement called BMI (body mass index) which is the individual's weight multiplied by 703 and then divided by twice the height in inches.

BMI of 25.9-29 is considered overweight; BMI over 30 is considered obese.

Sexual violence is notoriously difficult to measure, and there is no single source of data that provides a complete picture of the crime.

On RAINN’s website, we have tried to select the most reliable source of statistics for each topic.

The primary data source we use is the National Crime Victimization Survey (NCVS), which is an annual study conducted by the Justice Department.

To conduct NCVS, researchers interview tens of thousands of Americans each year to learn about crimes that they’ve experienced.

Based on those interviews, the study provides estimates of the total number of crimes, including those that were not reported to police.

While NCVS has a number of limitations (most importantly, children under age 12 are not included), overall, it is the most reliable source of crime statistics in the U. We have also relied on other Justice Department studies, as well as data from the Department of Health and Human Services and other government and academic sources.
