- Surnames occurring once are not published; absence from the dataset is not zero.
- The publisher does not state whether the split is by a person's sex or by the grammatical gender of the surname form. The datasets are therefore neither summed nor compared numerically.
- The male and female datasets are separate and are never summed.

- Denominator: 21,197,537 people counted in the PESEL register — the sum of the published counts in this dataset, not Poland's population.
- The 1-in-X figure is rounded; the count of people is exact.
- Denominator: 21,560,302 people counted in the PESEL register — the sum of the published counts in this dataset, not Poland's population.
- A permanent registered residence is an address in the register — not an actual address, and not information about a family's roots.
- Shares are of the people with a registered voivodeship, not of every bearer of the surname.
- The size of the list itself changes between editions, so beside the count we show the share of that edition's list (“1 in X”).
