The Holmes Report and the International Communications Consultancy Organisation (ICCO) are seeking input into the 2014 World PR Report, which ranks the world’s biggest PR agencies and identifies key global industry trends and issues.

Firms seeking to participate in the ranking or provide information for the report can take the online survey here. Alternatively, you can download the survey here and return to pholmes@holmesreport.com by 21st March.

The information gathered in this survey will be used to compile the annual list of the 250 largest PR firms in the world, which serves as the basis for an estimate of the size and growth of the public relations industry globally.

It will also form the basis of the World PR Report 2014, produced in collaboration with ICCO. A new section in the report, sponsored byCapstone Hill, will look at how the industry can overcome the specific talent challenges it is facing.

Last year’s Report found a PR agency industry that is growing at around 8% per year, to approximately $11bn in fee income, employing at least 75,000 people.

Despite this growth, though, the study found that plenty of challenges persisted. PR agency leaders pointed to economic conditions as their biggest concern, alongside talent and new technologies. Meanwhile, overall industry optimism dipped slightly, despite obvious industry growth in both mature and emerging markets.
