Help with undergrad econometric project
Can you provide your research question in one concise sentence? It seems like you've proposed half a dozen topics some of which are peripherally related. You need a quantifiable dependent and independent variable as well as essential control variables. 

The question needs to be quantifiable and have a wealth of data already available. I'd highly recommend for your undergraduate paper instead of asking a question and then searching for the data to back up the answer, you instead peruse some interesting data sources and ask a question based on what is available. 

Check out sites like https://www.data.gov/open-gov/ which have a wealth of easily downloadable datasets that you can explore. Find datasets related to topics that you find interesting and go through the available data and begin to think of what can act as an independent or dependent variable. Base your question so that the dataset you have already found and think is interesting perfectly fits instead of the other way around.

Unless you plan to do original research it will be quite difficult to simply find data to fit your question unless you already knows it exists.
