Combining Datasets Questions (or Dataset Recommendations)

Hi all! This is probably a stupid question, but please someone just clarify for me without shaming me lol. If I am attempting to complete a research project (for a quantitative research methods class) on fear of crime and media consumption can I take two different datasets and combine them in order to run analysis on the variables? Or, does anyone know of any good survey datasets that contains variables I could use for this (or recode and use)? I apologize for the dumb question, but my professor has been no help. Thanks in advance!
