sexual_assault	int	Criminal Sexual Assault Arrests - In the federal UCR program the underlying offense/cherge leading to arrest is called "Rape", however in Illinois the relevant criminal statutes are called criminal sexual assault. Prior to 2014 the federal UCR program used the term forcible rape, a term which only included "the act of a man having sexual bodily connections with a woman; sexual intercourse.". Since 2014, the definition of rape is " Penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim. Force is not a required element." The latter is largely consistent with Illinois criminal statutes related to the Illinois offense of criminal sexual assault since 1984.	Non-negative integer.

Illinois criminal statutes allows battery and assault offenses to be elevated to aggravated based on who the victim is (police officer, correctional officer, fireman, private security officer, teacher, emergency medical technician, disabled person, person age 60 years or older, or pregnant victim); where the incident took place (public way, public property, or sports or entertainment arenas when events are scheduled); or if the assailant conceals his identity (hooded, robed, or masked).
