A 2002 study found that Zipf's law was rejected for 53 of 73 countries, far more than would be expected based on random chance. The study also found that variations of the Pareto exponent are better explained by political variables than by economic geography variables like proxies for economies of scale or transportation costs. A 2004 study showed that Zipf's law did not work well for the five largest cities in six countries. In the richer countries, the distribution was flatter than predicted. For instance, in the United States, although its largest city, New York City, has more than twice the population of second-place Los Angeles, the two cities' metropolitan areas (also the two largest in the country) are much closer in population. In metropolitan-area population, New York City is only 1.3 times larger than Los Angeles. In other countries, the largest city would dominate much more than expected. For instance, in the Democratic Republic of the Congo, the capital, Kinshasa, is more than eight times larger than the second-largest city, Lubumbashi. When considering the entire distribution of cities, including the smallest ones, the rank-size rule does not hold. Instead, the distribution is log-normal. This follows from Gibrat's law of proportionate growth.

Created by series producer Shonda Rhimes, the character was introduced in season two as Dr. Derek Shepherd's best friend who acted as the catalyst for the end of Shepherd's marriage when Shepherd caught Sloan sleeping with his wife, Dr. Addison Montgomery. Soon after moving to Seattle Grace Hospital as an attending specializing in plastic surgery to reconcile with Derek, Mark earned the nickname ``McSteamy'' for his good looks by the female interns. Mark's focal storyline in the series involved his romantic relationship with Dr. Lexie Grey. Both he and Lexie sustained life-threatening injuries after an aviation accident in the eighth season finale, which resulted in their deaths. Seattle Grace is later renamed Grey-Sloan Memorial Hospital in their memory.
