The effects on criminal behaviour of raising the minimum wage for those aged 25 and over in the United Kingdom are analysed, using data on police stop and search activities. A 1% increase in the minimum wage raises the fraction of people stopped by the police by 2.96%, the fraction of people caught with an incriminating item by 1.43%, and the fraction of people arrested as a consequence by 1.27%. This effect is almost entirely driven by drug searches made outside business hours, suggesting that the minimum wage raises crime principally by raising disposable income – and drug consumption – among workers.
