Exercise: My County's or Metropolitan Region's "Location Quotients"

(http://faculty.washington.edu/krumme/350/exercises/lq.html)


Go to: Resources for "Location Quotient"

Exercise::

The purpose of this exercise is to gain a very basic understanding of the relative size and role of different economic activities in your county or metropolitan area and of the use of the "location quotient" to measure the unevenness in the distribution of these activities, however inadequately. I want you to use employment or occupational data even if you feel that your "field" of interests is not directly employment related. Find employment or occupational categories which come closests to what you have in mind as a field. If in doubt, send me an Email... If you feel that you should use demographic data (such as Asian immigrants) for L.Q. calculations, please do so in addition to your employment or occupational L.Q.s

  1. Formulate one or two simple questions or propositions which are related to the relative importance of some employment facet related to your topical specialization (such as "retail activities") in the context of your county or metropolitan area ....

  2. Calculate the full slate of location quotients for "all" economic activities (possibly after appropriate aggregation of categories other than those important for your topical field) in your county or metropolitan area using Washington State AND the United States as the benchmark regions. In addition, calculate at least one LQ (which relates to your topical interests) using a third benchmark region (such as the "Pacific Northwest" or the "Pacific States" or "all Westcoast Metropolitan Regions".
    1. Be very explicit as to how you did your calculations.
    2. Be very specific as to the data you have used (so that any reader can readily replicate your calculations). [You will find a more complete hypothetical example here]

    		  Total employment or population of Island County
