Prostitution laws varies widely from country to country, and between jurisdictions within a country. At one extreme, prostitution or sex work is legal in some places and regarded as a profession, while at the other extreme, it is considered a severe crime punishable by death in some other places. A variety of different legal models exist around the world, including total bans, bans that only target the customer, and laws permitting prostitution but prohibiting organized groups, an example being brothels.
