While Zipf's law works well in many cases, it tends to not fit the largest cities in many countries.
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.
Because exceptions are so easy to find, the function of the rule for analyzing cities today is to compare the city-systems in different countries.
The rank-size rule is a common standard by which urban primacy is established.
A distribution such as that in the United States or China does not exhibit a pattern of primacy, but countries with a dominant "primate city" clearly vary from the rank-size rule in the opposite manner.
Therefore, the rule helps to classify national (or regional) city-systems according to the degree of dominance exhibited by the largest city.
Countries with a primate city, for example, have typically had a colonial history that accounts for that city pattern.
If a normal city distribution pattern is expected to follow the rank-size rule (i.e.
if the rank-size principle correlates with central place theory), then it suggests that those countries or regions with distributions that do not follow the rule have experienced some conditions that have altered the normal distribution pattern.
For example - the presence of multiple regions within large nations such as China and the United States tends to favor a pattern in which more large cities appear than would be predicted by the rule.
By contrast, small countries that had been connected (e.g.
colonially/economically) to much larger areas will exhibit a distribution in which the largest city is much larger than would fit the rule, compared with the other cities--the excessive size of the city theoretically stems from its connection with a larger system rather than the natural hierarchy that central place theory would predict within that one country or region alone. 
An Australian passport does not, in itself, entitle the holder to enter another country.
To enter another country, the traveller must comply with the visa and entry requirements of the other countries to be visited, which vary from country to country and may apply specifically to a particular passport type, the traveller's nationality, criminal history or many other factors.
According to the ""Henley Visa Restrictions Index 2013"," Australian passport holders can visit 167 countries and territories visa-free or with visa on arrival, and Australia is currently ranked 6th in terms of travel freedom (21st, counting multiple country per rank), ranked behind New Zealand (5th placing, 168 countries) but above South Korea (7th placing, 166 countries). 
This article includes a sortable table of the 50 United States, the District of Columbia, and territories ordered by population density.
Population density is calculated as resident population divided by total land area.
Resident population is from the United States Census Bureau estimates for July 1, 2011, and total land area is also from the Census Bureau.
The population density of the United States is relatively low compared to many other developed countries due to its size and the advent of modern transportation during its settlement.
For example, the population density of the U.S. is one twelfth that of the Netherlands, and one fifteenth that of South Korea (as of 2010).

Visa requirements for Australian citizens are visa requirements imposed by other states on entry by Australian citizens who wish to enter into their country using an Australian passport.
According to the ""Henley Visa Restrictions Index 2013"," holders of an Australian passport can visit 167 countries and territories visa-free or with visa on arrival, and Australia is currently ranked 6th in terms of travel freedom (21st, counting multiple country per rank), ranked behind New Zealand (5th placing, 168 countries) but above South Korea (7th placing, 166 countries).
Besides visa requirements, most countries specify other requirements which preclude the entry of Australian and other citizens into their country, for example a prospective entrant has a criminal history, or health issues, evidence of sufficient funds, evidence of ticket for exit, etc. 
 "For use of this rank in other countries, see admiral of the fleet" Admiral of the fleet (AF) is the highest rank in the Royal Australian Navy (RAN), but is a ceremonial, not active or operational, rank.
It equates to the rank code O-11.
Equivalent ranks in the other services are field marshal and marshal of the Royal Australian Air Force.
Like those ranks, admiral of the fleet is a five-star rank.
The subordinate naval rank, and highest active rank in the RAN, is admiral.
This rank is only held when the Chief of the Defence Force is a naval officer.
The highest permanent rank in the RAN is vice admiral, held by the Chief of Navy.
