Need To Improve My Skills And Need A Data Set For Research

It would be preferred if I had a data set looking at higher education, community education, emergencies, emergency medical technicians, films, and or anything to do with social gerontology. I am supposed to be improving my SAS, Stata and Spss skills. I’m supposed to be working with data for my research project but the data I have is either to big for me to be able to open, I can’t be approved to use it, or isn’t a big enough dataset. I am trying to get better with using datasets but I need ones that are free to use. Please save me from the failure that is writing my own dataset.
