Minimum wage rates vary greatly across many different jurisdictions, not only in setting a particular amount of money—for example $7.25 per hour ($14,500 per year) under certain US state laws (or $2.13 for employees who receive tips, which is known as the tipped minimum wage), $11.00 in the US state of Washington, or £8.91 (for those aged 25+) in the United Kingdom—but also in terms of which pay period (for example Russia and China set monthly minimum wages) or the scope of coverage. Currently the United States federal minimum wage is $7.25 per hour. However, some states do not recognize the minimum wage law, such as Louisiana and Tennessee. Other states have minimum wages below the federal minimum wage such as Georgia and Wyoming, although the federal minimum wage is enforced in those states. Some jurisdictions allow employers to count tips given to their workers as credit towards the minimum wage levels. India was one of the first developing countries to introduce minimum wage policy in its law in 1948. However, it is rarely implemented, even by contractors of government agencies. In Mumbai, as of 2017, the minimum wage was Rs. 348/day.
