Whatever number is forecasted, it’s usually an average. So, some people get higher (maybe they are in a more generous organization, maybe their skill is niche, maybe their industry is growing etc) and some people may get lower salary increase. (maybe the skills are too general, maybe they are in the wrong company, maybe the industry they are working is no longer growing). Some countries may have a lower number because their currency is already very strong, anything too high for just a few years will make them very uncompetitive in the long run.
