Definition
- Central city
- If a municipality has at least 10,000 DID population, and is not a suburb of any other municipalities, it is defined as a central city.
- Even if a municipality is a suburb of another, it can still be defined as a central city. In this case, a municipality must have workers working there more than those living there. It must also have the DID population of at least 10,000, or a third of the population of the central city.
- Suburb
- If a municipality A has more than 10% of its population commuting to a central city B, A is defined as a (primary) suburb of B.
- If there are multiple such cities for a suburb A, the one with the most commuters from A is defined as A's central city.
- If a municipality A has more than 10% of its population commuting to another suburb B, and if no other municipalities have more commuters from A, A is defined as a secondary suburb or lower of B.
- If a municipality A has more than 10% of its population commuting to B and vice versa, the one with the higher percentage of commuters is defined as a suburb of another.
- If a central city comprises multiple municipalities, numbers of commuters to all those municipalities are counted for the calculations above.
