How does statistical analysis differ when analyzing the entire population rather than a sample?

I need to do some statistical analysis on legal cases. I happen to have the entire population rather than a sample. I'm basically interested in the relationship between case outcomes and certain features (e.g., time, the appearance of certain words or phrases in the opinion, the presence or absence of certain issues).
Should I do anything different than I would if I were using a sample? For example, is a p-value meaningful in this kind of case?
If it matters, the population is large (many thousands of cases) and spans several years.
