# Analysing the entire population [duplicate]

I am performing an analysis in which the unit of analysis is a geographical area (more precisely, an LSOA). This is a case when the sample analysed can represent the entire population (all 32000+ LSOAs in England). How do we interpret, in this case, the point and interval estimates of a, say, regression analysis?

You would probably be more interested in effect size measures that quantify how well your model predicts your DV (in this case, $R^2$). For example, you might have an $R^2$ of 1, which means your model perfectly predicts your DV, or .01, which means it explains 1% of the variance. Whether or not that is important to you is a human judgment call.
