The generation born between 1995 and 2012, called iGen (or sometimes Gen Z), is very different from the Millennials, the generation that preceded it. According to Jean Twenge, an expert in the study of generational differences, one difference is that iGen is growing up more slowly. On average, eighteen-year-olds today have spent less time unsupervised and have hit fewer developmental milestones on the path to autonomy (such as getting a job or a driver’s license), compared with eighteen-year-olds in previous generations.
