What the table shows

Masovian alone has 939,049 entities, 20.4% of all in Poland – 9.3 times as many as Opole (100,944), the smallest voivodeship by this measure.
The five largest voivodeships (Masovian, Silesian, Greater Poland, Lesser Poland, Lower Silesian) together hold 58.6% of entities; the six smallest (Subcarpathian, Warmian-Masurian, Lubusz, Holy Cross, Podlaskie, Opole) 16.2%.
Only 6 of 16 voivodeships are above the arithmetic mean of 287,406 entities; the median is 204,857. A few large regions pull the mean up.
1,282 entities in the register have no voivodeship assigned (<0.1% of the total).

The table describes the register. It does not explain the differences between regions, and we do not draw conclusions about their causes.

Definitions

Entity declaring business activity. A national economy entity in the REGON register that, according to GUS, declares that it carries out business activity. The count excludes natural persons running only individual farms.
Voivodeship. Assigned by GUS according to the entity’s registered address, not the area where it operates or where its branches are.
Share. The voivodeship’s count divided by the total for Poland (including entities without a voivodeship), rounded to one decimal place.
Cumulative share. The sum of shares of all voivodeships up to and including the given row.

Methodological notes

Source file: GUS, quarterly information on national economy entities in the REGON register, table 1, as of 30 June 2026, published 16 July 2026 (XLSX). Check: the 16 voivodeships plus “no voivodeship” add up exactly to the total of 4,599,771.
GUS also publishes a separate, broader total of all registered entities – 5,442,900 in December 2025 – which is not comparable with the count of entities declaring activity used here.
These are official statistics, not records of our database. How many records we can deliver for a given voivodeship, we state for each enquiry.
