It’s hard to tell when exactly coding bootcamps started, but they became more popular around 2011. Through the past decade, they’ve proven to be a very popular path for young and more inexperienced coders. Now, it seems that there’s no stopping them.

Just this past year, there were 23,043 graduates from coding bootcamps in the US and Canada. That’s according to a report from Course Report, which also adds that bootcamps in those region represent a $309 million industry.

Furthermore, a study made by HackerRank revealed some trends that are ongoing in the industry. For starters, 32% of hiring managers reported having hired a bootcamp graduate, and 72% of those believed their hires were either equal or even better than more conventional professionals thanks to an apparent ability of learning new technologies quickly.

Another interesting, but perhaps more obvious insight, was the fact that people from Gen Z were more likely to use bootcamps. “As Gen Z comes to rely more heavily on non-traditional education sources like bootcamps, they’re poised to become a key talent pool,” writes the report.

Another interesting point was that full-stack developers were the most in-demand in the pool of professionals, many of them coming from bootcamps. “The emphasis on full-stack developers was most pronounced in small companies (1-49 employees), 43% of which ranked the role as their top priority.” The reason? Simple cost effectiveness: while the report admits that “full-stack developers” is a disputed profile, “most agree that they should have a basic understanding (or better) of all layers of a tech stack, and should be able to generate a minimum viable product on their own.”
