1. around 18% for models anywhere up to 24% is considered LEAN
2. Normal girl= 20-30% Super skinny model maybe 12% When I was in college, my whole Cross Country team took underwater(only accurate measure) bodyfat tests and most of the div1 track girls were over 20%
3. avarage
4. Adult females: 19%-29% Fitness models: 15%-18% P.S. Skinny does not equal lean. Catwalk models are not leaner than fitness models or body builders even if they look skinnier and weigh less. 12% body fat looks like this: http://effectivebodybuilding.files.wordpress.com/2008/06/female_bodybuilding.jpg not like this: http://i125.photobucket.com/albums/p70/zafu/Skinny%20Models/skinny_models.jpg
5. Last year I was 19% and could easily have lost more fat without being considered "model thin" but then again I am more muscular than many women. I would say 16-17% would be ideal for me, but depends on the woman too.
6. 19-24% is the norm for woman under 19 is considered unhealthy over 24 is considered unhealthy I learned this last year in health class
