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.

Famous quotes containing the word definition:
“Beauty, like all other qualities presented to human experience, is relative; and the definition of it becomes unmeaning and useless in proportion to its abstractness. To define beauty not in the most abstract, but in the most concrete terms possible, not to find a universal formula for it, but the formula which expresses most adequately this or that special manifestation of it, is the aim of the true student of aesthetics.”
—Walter Pater (18391894)
“Perhaps the best definition of progress would be the continuing efforts of men and women to narrow the gap between the convenience of the powers that be and the unwritten charter.”
—Nadine Gordimer (b. 1923)
“Mothers often are too easily intimidated by their childrens negative reactions...When the child cries or is unhappy, the mother reads this as meaning that she is a failure. This is why it is so important for a mother to know...that the process of growing up involves by definition things that her child is not going to like. Her job is not to create a bed of roses, but to help him learn how to pick his way through the thorns.”
—Elaine Heffner (20th century)
