Pros
You work with a supportive team of researchers. It's a great first job to learn new technical skills (Stata, Excel, ArcGIS mostly) and managing work flow to have accurate, detail-oriented output. Work is very well-structured, and there's occasionally idle time which is a nice break. Generous benefits and overtime work perks. Travel is rare, which is actually really nice.
Cons
Very limited chances for upward mobility. Skills in Stata don't translate that well to industry standard (Python, R, SQL) so that has to be self-taught, though the basic concepts carry over well. There isn't a clear transition out of the company even though researchers typically stay for only 2 years--many go on to graduate school. Not many networking opportunities.
