I'm a bit tired here so maybe it is there and I'm not seeing it but of course it doesn't say anything that the Graphic Design jobs increased by 8% unless we know what the rate was of jobs on offer was between the various periods was, probably to compare with graphic design job growth during previous years.
Yeah agreed, there was quite a lot of layoffs during the same period too, would have liked to see it normalised or compared against the overall labour market which still wouldn't be perfect because so industry and skill levels might've been hotter and colder but it makes the argument for causality stronger
Same applies to other categories of course.
