Data Sets

Dear academic researcher:

I placed here all the police stops data sets to which I have access. The goal is to make it a little easier for you, a serious researcher, to work on policing topics. I hope that, inspired by the availability of the data, you go on to write beautiful and important papers.

On this webpage, you find a brief description of each data set, and other work that has made use of that data set. You will also find a link to a password-protected site where you can download the data set. Upon clicking on that link, you will be asked for a user name and password. They can be obtained by writing me at nicola@nicolapersico.com. I am asking that you do not share this password, or the data, with anyone.

May I ask, as a personal courtesy, that you keep me informed of the progress you make in any work that is based on these data. Being kept informed of your progress will be my reward for making the data public and for maintaining the site.

One last word. Please accept the datasets as they are. They may not be fully documented, and in some cases the coding of some variables may be unclear. Please, do not ask me for details about the data. Instead, attempt to find out for yourself and, if you succeed, please let me know and I will post a note for future users.

Enjoy!

Nicola


PS: if you have data sets that you would like to share with others, please contact me. You are welcome, of course, to post it on this webpage or, if you prefer to retain more control over the data, we can arrange things in a way that is suitable for you (like giving out your email, for example).
