The proportion of the current advertising and marketing workforce in London who have migrated here from abroad in the last 12 months is three times as high as the corresponding figure in New York, and also higher than in Paris and Amsterdam. More than a third of these recent migrants come from European Union (EU) countries, with many others arriving from the United States and Australia. Although London attracts the majority of this international talent, more than a quarter (29%) of migrants to the UK have come to work outside London. Interviewees for this report, representing a broad cross-section of companies both buying and selling advertising services, consistently emphasise the essential contribution of non-British workers to the industry. Without such diversity in the workforce, creativity and customer service would suffer dramatically.
