If you live in a city area then you will have more piercings.

The p-value<0.59 indicates that we can reject the hypothesis. The results are not statistically significant. There is no difference between the groups of location and the number of piercings.

The data analysis shows that there is evidence to reject the hypothesis. It seems that the number of piercings are relatively even despite location. The city area has more people with more piercings but that only inflates the average number of piercings. In general, the number of piercings based on locations are basically the same in the average.

The results of the analysis show that there are as many members in each category then would be expected from chance alone. So we now know that location doesn't determine or help influence whether or not adolescents would get more piercings. The results can be applied to the real world in the sense that parents do not need to worry about the environment influencing the number of piercings. So if a kid lives in a big city where there is more variance and possible external influences that may lead to kids getting even more piercings as a way to "fit in" or to be "unique". The hypothesis was disproven by the results so living in a city area does not mean that you will have more piercings.

Not knowing too much about the data collection process and the generalizability of the results, I would say that this study would not be good to generalize from. I would make sure that the selection process for the survey could be as random as possible but also making sure that the survey is reliable enough with a suitable cronbach's alpha so that the data can be generalized. To clear things up though, I would make sure to have a clear distinction of what constitutes a big city or city and suburb so that the categories area as clear as possible. Otherwise, the collection process and the survey itself are good for this topic. The data cannot be collected other than with a survey. An observational study could be possible but it would be hard to make a distinction other than something like gender or race.
In general the data shows that the average number of piercings does not change from location to location. Most locations vary around the mean of 1.86 but city people just have more piercings based on raw data. From a statistical perspective, these are not important because they can shift the mean. Most people have at most 3 people, with variants here and there.
