They include two Crown dependencies: the Bailiwick of Jersey, the largest of the islands; and the Bailiwick of Guernsey, consisting of Guernsey, Alderney, Sark and some smaller islands. They are considered the remnants of the Duchy of Normandy and, although they are not part of the United Kingdom, the UK is responsible for the defence and international relations of the islands. The Crown dependencies are not members of the Commonwealth of Nations or of the European Union. They have a total population of about 164,541, and the bailiwicks' capitals, Saint Helier and Saint Peter Port, have populations of 33,500 and 16,488, respectively. The total area of the islands is 198 km.

To resolve those issues, one economist proposes a cost-allocation model that would determine the optimal allocation of USPS's common costs by finding the share of costs that would maximize USPS profits from its competitive products. Postal regulators could use such a cost model to ensure that the Postal Service is not abusing its statutory monopoly by subsidizing price cuts in competitive product markets with revenue obtained from the monopolized market.

The association with track length and duration also varies, although longer track (and longer lived) tornadoes tend to be stronger. In the case of violent tornadoes, only a small portion of the path area is of violent intensity; most of the higher intensity is from subvortices. In the United States, 80% of tornadoes are EF0 and EF1 (T0 through T3) tornadoes. The rate of occurrence drops off quickly with increasing strength--less than 1% are violent tornadoes (EF4, T8 or stronger).
