Urban Employment Area - Definition

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:

    “Scientific method is the way to truth, but it affords, even in
    principle, no unique definition of truth. Any so-called pragmatic
    definition of truth is doomed to failure equally.”
    —Willard Van Orman Quine (b. 1908)

    “The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.”
    —William James (1842–1910)

    “It’s a rare parent who can see his or her child clearly and objectively. At a school board meeting I attended . . . the only definition of a gifted child on which everyone in the audience could agree was “mine.””
    —Jane Adams (20th century)
