To find the richest zip codes in Maryland, we look up the most recent income and demographic statistics from the US Census Bureau. Next, we exclude any zip codes that have a population fewer than 500 people and exclude zip codes with a margin of error greater than 50% of the estimate.

We do this to try and make the data less likely to be skewed by outliers with very small areas or estimates that are not very accurate.
